Abstract

Design considerations and experimental results of a dual‐band circularly polarized stacked microstrip antenna for GPS operations at 1227 and 1575 MHz are presented. The antenna is achieved by stacking two corner‐truncated square microstrip patches. The obtained circular polarization (CP) bandwidths, determined from 3‐dB axial ratio, are about 15 MHz (about 1.2%) and 17 MHz (about 1.1%) at 1227 and 1575 MHz, respectively. Good CP radiation patterns and antenna gain have also been observed. © 2002 Wiley Periodicals, Inc.

## Abstract A new integrated structure of a two‐element microstrip patch antenna with two feeds for DCS/GPS dual‐band operations is proposed. The radiating element for DCS (1710–1880 MHz) operation is a broadband low‐profile cylindrical monopole top loaded with a shorted square patch, which gives a
