Dual‐frequency operation is achieved from a compact microstrip antenna by loading a pair of narrow slots close to its radiating edges. The two frequencies have parallel polarization planes and similar radiation characteristics. The ratio between the two operating frequencies can be tuned in the range (1.14–1.24), which is much smaller than that of similar designs. The above excellent radiation characteristics are achieved along with an area reduction of ∼75% compared to the standard rectangular patch. © 2001 John Wiley & Sons, Inc.
