AN/FPS- 8. 5 Phased Array. Parasitic Element Patch AntennaRadar Facility operated by U. In general, the performance of an antenna array. Four- element microstrip antenna array (phased array). Cell- tower Antenna Array. These Antenna Arrays are typically used in groups of 3 (2 receive antennas and 1 transmit antenna). An origin and coordinate system are selected. N elements are positioned, each at location given by. The positions of the elements in the phased array are illustrated in the following Figure. Figure 3. Geometry of an arbitrary N element antenna array. The output from these. N weights - . - and added together as shown in Figure 4. Figure 4. Weighting and summing of signals from the antennas to form the output in a Phased Array. However, I haven't answered what the benefits of. To understand what happens in an antenna array, navigate to the next section on Antenna Arrays. Benefits of Antenna Arrays. To understand the benefits of antenna arrays, we will consider a set of 3- antennas located along. Figure 4. Figure 4. Example 3- element Antenna Array receiving a plane wave. The E- field of. the plane wave (assumed to have a constant amplitude everywhere) can be written as. In the above, k is the wave vector. Further, assuming. E- field at the antenna location. Antenna Patterns and Their Meaning. The patterns from each antenna are shown and explained in. 11 useful links about Patch Antenna collected in Antennas/Patch by The DXZone. Hence. for antenna i, the received signal is. The received signals are distinct by a complex phase factor, which depends on the antenna separations. If the signals are summed together, the result is. The interesting thing is if the magnitude of Y is plotted versus. The. result is given in Figure 5. Figure 5. Magnitude of the output as a function of the arrival angle for Antenna Array. In contrast, when the angle of arrival. In. this manner, a directional radiation pattern is obtained even though the antennas were assumed to be isotropic. Even. though this was shown for receiving antennas, due to. No portion can be reproduced. Copyright antenna- theory.
