A Dual-Band Circularly Polarized Stacked Microstrip Antenna with Single-fed for GPS Applications

摘要：

A single probe feeding stacked microstrip antenna is presented to obtain dual-band circularly polarized (CP) characteristics using double layers of truncated square patches.The antenna operates at both the L1 and L2 frequencies of 1575 and 1227 MHz for the global positioning system (GPS).With the optimized design,the measured axial ratio (AR) bandwidths with the centre frequencies of L1 and L2 are both greater than 50MHz,while the impedance characteristics within AR bandwidth satisfy the requirement of VSWR less than 2.At L1 and L2 frequencies,the AR measured is 0.7 dB and 0.3 dB,respectively.
