| Abstract | Abstract : Measurements on an experimental model of a 127-beam multiple-aperture EHF antenna are reported. Featuring a hexagonal arrangement of seven individual multiple-beam lens antennas, the 44-GHz antenna array was designed for adaptive nulling applications in which 14 beams could be accessed to simultaneously provide 1.50 theater coverage and two independent agile beams. Antenna pattern and gain measurements for all 127 beams and results from simulated nulling experiments using a simple mechanically driven weighting network are discussed. Null depths of 30 dB and nulling resolutions of 0.1 deg are shown. The measurement results support the viability of this type of adaptive antenna system. |
