Abstract

A dual-band circularly polarized stacked microstrip antenna for precise global positioning system (GPS) applications is proposed and experimentally studied. By stacking two different corner-truncated square patches in a dielectric substrate layer, the microstrip antenna for dual-frequency circular polarization (CP) can be achieved without an air layer between the two stacked patches. The top patch has a pair of truncated square corners, and the bottom patch has a pair of truncated isosceles triangular corners. The antenna design for dual-band GPS at 1575 MHz and 1227 MHz is demonstrated here. Details of the obtained dual-band CP performances are presented and discussed.
