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
