Abstract

This paper describes a new aperture‐coupled microstrip patch antenna with H‐shaped slots for dual‐band and dual‐polarized operations. Two orthogonal modes are excited in a single long rectangular patch to achieve the two resonant frequencies with a separation of more than 2:1. By using five parasitic conducting strips stacked on the driven patch, the impedance bandwidths can be increased and isolation of more than 34 dB between the two ports is obtained. Moreover, the cross‐polarization levels for the two polarizations are found to be better than 25 dB. © 2003 Wiley Periodicals, Inc. Microwave Opt Technol Lett 38: 44–46, 2003
