Beam Shape Reconfigurability of Wide-Scan Focal Plane Array Antennas

In this contribution we investigate the flexibility of wide-scan focal plane array antennas at mmWave. Based on measurement data, it is shown that highly directive beams can be generated, as well as wide beams with increased transmission power which are useful in stormy conditions where the rain attenuates the signal and the antenna tower twists and sways due to the wind. In addition, it is shown that sum and difference beams can be generated which can be used for radar sensing applications. The directivity is between 31.4dBi and 37.2dBi depending on the beam type, with a relative transmission power between 10.5dB and 18.1dB, compared to the maximum transmission power of a single antenna element
