#TechTuesday: Antenna Polarization 101

Posted by | #TechTuesday, MP Antenna Blog

One of most important topics when choosing an antenna is being aware of the polarization. Polarization exists due to the fact that all energy travels in the form of a 2-Dimensional wave unlike the 3-Dimensional world that we live in. This physical property of wave propagation can explain why a horizontally polarized antenna has trouble communicating with a vertically polarized signal. Let’s start by looking at a visual representation of these two types of polarization.

Polarization_1

While it may become clear how these waves travel it does not explain why the two are not compatible. The image above represents how the wave is sent from the transmitting antenna and in order for both antennas to communicate efficiently, they must have matching polarizations.  Think of the receiving antenna as a coin slot on a vending machine, and the transmitting antenna as a coin. The orientation of the slot on the vending machine can be either vertical or horizontal much like the polarization of the receiving antenna.  Now, what happens when you try to insert a coin vertically in a horizontal vending machine coin slot?  The same question can be asked when you attempt to transmit a from a vertically polarized antenna, to a horizontally polarized antenna, and the answer is pretty much the same as the vending machine coin slot analogy.

In a scenario where you have direct line of sight between the transmitting and receiving antenna, the polarization will have to line up for the two antennas to communicate efficiently. It isn’t impossible for two different polarized antennas to communicate but it is severely limited, and often made possible due to refraction and reflection of the signal. Generally speaking, it is a good rule of thumb to match polarizations when utilizing linear polarized antennas.  Most antennas today transmit and receive using vertical polarization.  In the real world those waves reflect off of everyday objects, which can change the polarization of the wave.  This would lead to a decreased signal strength at the receiving antenna.  Stay tuned for next week’s #Techtuesday where we will be covering Multi-Polarized antennas and how they solve polarization mismatch, polarization refraction, and polarization reflection.

#TechTuesday: How to fix Multipath issues

Posted by | #TechTuesday, MP Antenna Blog

Multipath is a common occurrence with wireless devices as we discussed in last week’s #TechTuesday. To recap, multipath occurs when multiple signals from the transmitting antenna reach the receiving antenna via either a direct line of sight or by reflecting off of objects such as trees, walls, or furniture. These signals converge on the receiving antenna and can cause destructive interference, which can reduce the signal strength or cause the signal to drop out completely. Before you clear the office of all its furniture or cut down that tree in your backyard, there is a simple way to reduce the effect of multipath and the answer is spatial diversity.

Spatial diversity is usually achieved by having two or more antennas connected to separate radios inside a wireless device. In the picture below there are two receiving antennas that are both picking up the signal from the transmitting antenna. In the real world both antennas will be picking up multiple signals due to multipath and there is a chance that one of them is in a “dead” zone. However, with two antennas the receiving device  will have an option to choose the radio and antenna that is receiving the best signal.

Spatial Diversity Picture

This is why Wi-Fi routers have two, three, or even six antennas on them. The router is receiving multiple signals from the multiple antennas, but is only using the one that has the strongest signal. Having six antennas on a Wi-Fi router might seem like overkill, but in today’s wireless world people would do just about anything to make sure they have the best signal possible. However, is there a way to combine the same spatial diversity achieved with multiple into one antenna? The answer is Yes! Every antenna manufactured by MP Antenna has built in spatial diversity that helps eliminate multipath and creates a stable connection in real world environments!

MP Antenna utilizes patented technology that gives the antenna a unique three dimensional shape. Most antennas you see are dipole antennas, which are mostly always made from straight wire. For the dipole antenna to receive a signal, the radio wave has to “hit” this single piece of wire. This means the effective area for a dipole antenna to receive a signal is quite small. With a MP Antenna, you have a larger effective area in which the signal can be received due to the three dimensional shape as seen in the picture below.

Dipole antenna

The MP Antenna creates spatial diversity by having this three dimensional shape. By having spatial diversity, the probability of the MP Antenna receiving a strong signal and not being in a dead zone due to multipath is greater than that of a dipole and many other antennas. One portion of the MP Antenna could be in a null, while another portion could be receiving a usable signal. This is just not possible with any other antenna, making a MP Antenna the best solution to overcome multipath issues. Fixing multipath problems is only one of many advantages using a MP Antenna has over the competition. Check back for the next #TechTuesday where we will start discussing more!

#TechTuesday: Multipath Explained

Posted by | #TechTuesday, MP Antenna Blog

In an ideal world for wireless communication there would be no object in-between or around the transmitting and receiving antennas. With no objects between the antennas, an ideal line of sight can be achieved with a proper setup. However, in the real world there are trees, buildings, and even the Earth that make a perfect line of sight just about impossible. Wireless signals reflect off these objects on their way from the transmitting antenna to the receiving antenna, creating multiple paths for the signal to travel. This phenomenon is known as multipath.

The receiving antenna receives the transmitted waves via multiple directions due to multipath objects; therefore the signal is picked up multiple times. In the figure below there are two “signals” being transmitted, one has a direct line of sight and the other is reflected off an object.

Multipath Picture

 

The reflected signal has a longer distance to travel than the direct line of sight, which could cause the signals to arrive at different phases and cause deconstructive interference. When this occurs the radio will see a weaker signal from the receiving antenna or could even cause the signal to drop out completely.

When your cell phone loses all its bars or your car radio cuts out, your issue may be multipath. Mostly everyone knows that by moving to a different location the signal will usually improve. With the idea of multipath, you are moving to a spot where the reflected signals off of everyday objects are coming to a point where the magnitude of the interference between them is lower. Stay tuned for next week’s #TechTuesday where we will discuss how multi-polarized antenna designs mitigate multipath in wireless deployments!

#TechTuesday: Omnidirectional Radiation Patterns

Posted by | #TechTuesday, MP Antenna Blog

Which antenna is right for my deployment???

Antenna selection is by far the most commonly overseen task in designing a system or deployment. Why? Because antennas are boring… they are passive devices that offer zero analytics and no nifty software. They simply plug-in to sophisticated active devices, and take a back seat while the radio gets all of the credit. However, without the RIGHT antenna, or an antenna at all, your fancy software on your fancy radio will not work. Your devices will not connect, you won’t be able to provide your customers the service they need, and most likely someone will be complaining.

Antenna selection does not have to be a daunting task. The number one issue that we have seen over the years falls under the category of radiation pattern selection, specifically when it comes to Omnidirectional Antennas.   Lets look at a few radiation patterns and discuss where they work best.

Omnidirectional Dipole Antennas:

These antennas have a doughnut shaped radiation pattern and are ideal for connecting devices that are on the same plane and to either side of each other. These are commonly misused in in-building and mobile applications.  In mobile applications, Omnidirectional Dipole Antennas fail to have the proper patterning needed in order to connect to a tower that is on a much higher elevation.  In in-building applications, Omnidirectional Dipole Antennas fail specifically in point to multipoint deployments where the user can be standing directly underneath a transmitting antenna, and be in a dead zone.

FIGURE 1

 

Omni Directional HIGH GAIN Dipole

These are very similar to the Omni Directional Dipole, however, the gain is increased which in turn, reduces the beamwidth.  Again, these are ideal when a further reach is needed, but only when the transmit and receive antennas are on the same plane.

FIGURE 2

 

Hemispheric Antennas

These antennas are ideal for indoor deployments and mobile applications.  When mounted with the radome facing up in a mobile application, as shown in the plot below, the radiation pattern is directed above the antenna making it possible to transmit and receive signals from antennas that are at higher elevations.  When mounted with the radome facing down in an in-building application, a hemispheric antenna offers less of a dip in its pattern when standing directly underneath the antenna and ultimately reduces the possibility for dead spots.

#TechTuesday: Gain and Radiation Patterns Explained

Posted by | #TechTuesday, MP Antenna Blog

Antenna Gain?  What is it?  Gain is a key parameter for antennas that is a product of radiation directivity and electrical efficiency. To better understand antenna gain,  antenna designers utilize two dimensional, and three dimensional patterns to aid in proper antenna selection.  These patterns provide system engineers a visual of how a specific antenna radiates.

Figure 1

Figure 1

Figure 2

Figure 2

 

The above diagrams (Figure 1 and Figure 2) represent two cuts of a three dimensional radiation pattern, one for Azimuth (horizontal) and one for Elevation (vertical). This particular antenna was designed to be Omnidirectional with a peak gain at 2.4 GHz.  What this means to the customer is that the maximum efficiency and gain is achieved at this specific frequency. The first diagram represents the azimuth pattern of the antenna. To better understand the azimuth pattern, imagine looking down at the top of the antenna. Figure 3 is a 3D version of the antenna’s azimuth radiation pattern to help see how the two correlate.

Figure 3

Figure 3

 

The elevation pattern plot (figure 2) represents if you are looking at the antenna from the side. Figure 4 is the 3D plot to show how the elevation diagram correlates to the polar diagram.  Since it can be hard to see the gain drops near the elevation angle of 90 degrees, this plot is in wireframe.

Figure 4

Figure 4

 

Based on both the azimuth and elevation polar plots, a customer can determine where the antenna gets the best gain and select the most suitable antenna for their project. The example above shows an omnidirectional antenna with gain that is rather even at all azimuth angles. This will be drastically different from a directional antenna that will offer higher gain values that are concentrated in a particular direction. Stay tuned for our next #techtuesday where we will take a deeper dive into antenna patterns and further discuss antenna selection.

#TechTuesday: Frequency Explained

Posted by | #TechTuesday, MP Antenna Blog

Wireless technology is all around us, from a kid’s toy walkie-talkie to the newest smart phone in your pocket. We see and interact with these objects every day; however it is what we don’t see that makes this all possible, radio waves. These radio waves are continually transmitting information from one device to another and are constantly interacting with each other and their surroundings. But how can you sit in your house with the radio on, Wi-Fi connected, and talking on the cell phone at the same time? Even though all those devices are using radio waves, they are all operating at different frequencies.

Frequency is defined as the number of cycles of a wave per second. The unit of measurement for frequency is Hertz (Hz), 1 Hz is equal to one cycle (oscillation) per second. In the picture below the wave is oscillating 3 times per second, so the frequency would be 3 Hz.

frequency graph copy

When considering radio waves, the frequencies are noticeably higher than the above example as they operate between 3 kHz (kilohertz) and 300 GHz (gigahertz). One kHz is equal to 1,000 Hz and one GHz is equal to 1,000,000,000 Hz, that’s one thousand and one billion oscillations per second respectively. These frequencies are well below the visual spectrum frequencies needed for human eyesight, which is why we cannot see them.

With the use of an antenna, a wireless device is able to send and/or receive radio waves. The device and antenna are designed to only pick up a certain frequency, for example a Wi-Fi router will operate at 2.4 GHz and a FM radio operates around 0.1 GHz. These radio waves will still interact with each other, but the interaction is minimal due to the large frequency difference. This is why you can operate your radio, Wi-Fi, and cell phone at the same time, they all operate at different frequencies with minimal interference. Now have you ever picked up your cordless phone to see your Wi-Fi cut out? Many Wi-Fi routers and wireless phone both operate at 2.4 GHz. With the same operating frequency, the interaction between the radio waves is at a maximum and can cause interference with one another.

So the next time you are installing a wireless device into your office or house, take into consideration what frequencies are used. The subject of frequency is an important fundamental for wireless devices and antennas and as you can see now, it is what you can’t see that can make all the difference in this wireless world.
