Abstract

This letter presents a quad-band antenna with high gain for wireless local area network (WLAN) and Worldwide Interoperability for Microwave Access (WiMAX) communication covering the IEEE 802.11a/b and IEEE802.16d/e standards. The antenna consists of a microstrip feed line with a complementary microstrip-slot pair and a secondary slot element on a single dielectric medium. A single-band artificial magnetic conductor (AMC) surface was used as a reflector to achieve a unidirectional radiation pattern with an average gain of 9.3 dBi. The antenna was optimized to achieve a radiation efficiency of more than 90% in the WLAN and WiMAX frequency bands. The size of the antenna with the AMC reflector is 80×80×10 mm3. The radiation properties of the antenna were measured in a compact antenna range and simulated and measured results are presented.
