Abstract

The performance of the printed single and double layer phase correcting arrays is theoretically analysed. Then, the latest development of the single printed reflector is reported. The successful design of a practical size single printed reflector for the reception of direct broadcasting by satellite (DBS) is described. The reflector covers three full Fresnel zones and a quarter wave zone, and has a 59.4 cm diameter and 0.8 focal length to diameter ratio. A 43% maximum antenna efficiency and a bandwidth of greater than 10% were measured. The close-in sidelobes of the antenna are about -22 dB and the far-out sidelobes are below -30 dB
