✦ Synopsis

In this paper, we demonstrate a new and simple dualband design of a printed monopole antenna. The antenna consists of a crisscross monopole element with a microstrip feedline and a conductorbacked parasitic plane. The crisscross monopole and the conductorbacked parasitic plane are designed to achieve 2.4-and 5.2-GHz dualband operations for WLAN applications. The measured impedance bandwidth for 10-dB return loss is from 1.72 to 2.87 GHz and 4.41 to 6.09 GHz, covering the 2.4-and 5.2-GHz WLAN standards. The measured radiation patterns exhibit typical monopole-antenna radiation characteristics.
