Triple Band Microstrip Antenna with Defected Ground Plane

Abstract

In this rapid changing world in wireless communication systems, multiband antenna has been playing a very important role for wireless service requirements. Wireless local area network (WLAN) and Worldwide Interoperability for Microwave Access (WiMAX) have been widely applied in mobile devices such as handheld computers and intelligent phones. These two techniques have been widely considered as a cost-effective, viable, and high-speed data connectivity solution, enabling user mobility.

The thesis proposed a compact triple-band microstrip slot antenna applied to WLAN/WiMAX applications. This antenna has a simpler structure than other antennas designed for realizing triple-band characteristics which is just composed of a microstrip feed line, a substrate, and a ground plane on which some simple slots are etched.
