Abstract
Effects of different types of ground planes on the multipath mitigation and cross polarisation performance of a planar GNSS (L1 band) antenna have been investigated and presented. Simulations are done for circular patch antenna mounted on different types of ground planes including a finite metal disc ground plane, metallic cup and choke ring. Co-polar and cross polar radiation patterns are plotted for performance comparison. In addition to this, a novel technique is suggested to reduce the height of a choke ring antenna.
