A 30 GHz earth-station antenna has been developed to communicate with the AUSSAT B satellites. This paper outlines the design of a high-performance feed system and optimization of the antenna’s performance on a nearfield range. Tests conducted on two completed antennas displayed very close agreement between theory and experiment the measured and theoretical values of z are p = 0.02 mm and Q = 0.26 mm. The drop in efficiency due to these surface errors can be estimated from the equation t\,,=e-(4x~lU , which, with the above values, gives qSe= 0.9C. Gain loss due to departure from a paraboloid is then - 0.46 dB. 2
