Abstract

A novel compact single‐layer dual‐frequency microstrip antenna which uses an H‐shaped geometry with two U‐shaped slots embedded near the radiation edges, is presented. By changing the design parameters, the lower and higher resonant frequencies can be controlled easily, and a range of frequency ratios (1.716–2.363) can be obtained in this design. For the two operating frequencies of the proposed antenna, the same polarization planes and broadside radiation patterns are achieved. Compared to the regular dual‐frequency patch antenna, this antenna can realize a significant size reduction. © 2004 Wiley Periodicals, Inc.
