The AWR1843AOP antenna supports four receivers and three transmitters. This antenna was designed to achieve wide FOV in both azimuth and elevation. For more information regarding the FOV performance and the radiation patterns of the AWR1843AOP antenna please see the AWR1843AOP EVM User's Guide.
When the system operates in time-division multiplexed (TDM) MIMO mode, a non-uniformed, synthesized array of 12 antennas is achieved, as shown in Figure 2-4. The TDM mode of operation is achieved by transmitting chirps using TX1, TX3, and TX2 in an alternate fashion. With 4 synthesized antennas in azimuth direction and three in elevation direction this antenna provides an angular resolution of 29 degrees in azimuth and 38 degrees in elevation.
