Single-feed dual-frequency dual-polarized slotted square microstrip antenna

Abstract

A novel dual-frequency dual-polarized square microstrip patch antenna embedded with a slot is presented. The proposed antenna offers tunability of the frequency ratio between the two frequencies by adjusting the slot dimensions. This configuration also provides a size reduction up to ∼51 and 35% for the two modes as compared to a square microstrip patch antenna. © 2000 John Wiley & Sons, Inc.
