Design of Circularly Polarized Stacked Microstrip Antennas

摘要：

A simple technique is developed to improve the axial ratio (AR) bandwidth and quality of circularly polarized stacked microstrip antennas (CPSMAs) using a new C-type single feed.The proposed antenna has been optimized and fabricated,and the computed results agree very well with measurements.The antenna has a 3 dB AR bandwidth of 11.6％,gain is more than 8.2 dBi and the impedance bandwidth for VSWR less than 2 is 29％.The proposed feed optimization technique is useful for rapid design of circular polarized stacked microstrip antennas.
