UNSYMMETRICAL FEEDLINE FOR DESIGNING AN UWB PATCHANTENNA

摘要

In this paper a simple structure of Ultra Wideband (UWB)rnantenna is proposed by placing unsymmetrical feedline tornthe patch. The antenna offers excellent performance forrnUWB system, ranging from 3.6 GHz to 14.5 GHz. Thernantenna exhibits a 10 dB return loss bandwidth over thernentire frequency band. The antenna is designed on FR4rnsubstrate and fed with 50 ohms microstrip line. It is foundrnthat the frequency band depends on the width of thernpartial ground width, the width and position of thernfeedline of UWB antenna.
