Abstract In this paper, a novel dual‐frequency wideband aperture‐stacked patch antenna for cellular/PCS/IMT‐2000 base stations is presented. It consists of single microstrip patch with notches along the radiating patch, two dielectric substrates, and foam material. By the proper choice of the resonant aperture size and height of the foam material, dual and wideband characteristics can be realized. The measured impedance bandwidth (1:1.5 VSWR) of the designed antenna at the lower band (860 MHz) reaches 77 MHz and covers the cellular CDMA band (824–894 MHz). The measured impedance bandwidth (1:1.5 VSWR) of the designed antenna at the upper band (1960 MHz) is about 550 MHz and covers both the PCS (1750–1870 MHz) and IMT‐2000 (1920–2170 MHz) bands. Good broadside radiation with high gain (6.92–7.92 dBi) characteristics are also observed. © 2004 Wiley Periodicals, Inc.
