Abstract :
A novel array using microstrip elements for mobile satellite communications is presented. The cylindrical patch array consists of 18 circularly polarized microstrip patches, arranged around an inclined cylinder. The radiation elements were modified to reduce their resonant size, thus allowing for a compact array. A high-gain beam was achieved. It was electronically steered in azimuth for satellite tracking. A 10 dBic gain was achieved over elevation angles from 10 degrees to 50 degrees for a bandwidth of 1530 to 1660.5 MHz, ideal for mobile satellite coverage in Canada.<>
