Abstract :
Boeing has developed an active transmit phased array for use in the 14-14.5 GHz fixed satellite service (FSS) spectrum. The array consists of 254 actively controlled elements that radiate variable linear polarization. Measured boresight EIRP is 41 dBW with a beamwidth of 6°. Cross-polarization isolation is better than 25 dB at boresight. The antenna can track a satellite from a fixed or moving platform with angular tracking rates better than 30 degrees/sec and at grating lobe-free scan angles greater than 60° from zenith. The antenna, when used with Boeing´s commercially available 1515 element Ku-band receive array, provides mobile users a highly capable communications link utilizing geostationary FSS satellites
