Novel Microstrip Circular Patch Antennas

Abstract

Two new microstrip circular patches excited by a microstrip trarsmission line through an inserted coplanar section are presented. The integral equation for the unknown currents on the atenna and its feeding line is solved by the method of moments in which, the triangular subdomains discretization is employed. The calculated results show that the matching performances are improved for TM11 and TM12 modes. A good agreement between our theoretical and our experimental results is obtained.
