Microstrip-fed slot antenna with rectangular-shaped tuning stub for WLAN application

Abstract

This paper presents microstrip-fed slot antenna with rectangular-shaped tuning stub for WLAN application. The characteristics of antenna are proposed and analyzed for instance return loss, bandwidth, and far field radiation patterns. The measured results of the impedance matching for the proposed antenna show the impedance bandwidth, determined by -10 dB return loss, larger than 104% (2.0-6.35 GHz) of the center band, radiation pattern is bi-directional and average gain is 4 dBi. ©2008 IEEE.
