摘要：

A compact design of a single feed microstrip antenna for circular polarization (CP) is proposed and studied. CP is brought about by embedding a slot in a cross shaped patch. The structure. enables an area reduction of 46% as compared to conventional rectangular microstrip antenna. The antenna offers a 2:1 VSWR bandwidth from 1.53 to 1.61 GHz on a substrate of dielectric constant 4.4 and height 1.6 mm with a broadside radiation characteristic in the entire band. The 3 dB axial ratio bandwidth of the antenna is 5% with moderate gain that covers global positioning system (GPS) L1 band. Simulation and experimental results of the antenna are presented and discussed. (C) 2010 Wiley Periodicals, Inc.
