Abstract

A compact, CPW- fed rectangular slot antenna with octagon shaped tuning stub for WLAN and HIPERLAN/2 applications is presented. The antenna consists of CPW feed, rectangular slot and an octagon-shaped exciting stub. The octagon shaped stub is simple and has very few parameters, which are convenient to optimize. The proposed antenna is designed on an inexpensive FR4-epoxy substrate with dielectric constant (ε_r) of 4.4 and size of 30mm×30mm×1.6mm. The presented antenna has an impedance bandwidth from 5.125GHz - 5.8GHz (VSWR<;2), maximum gain of 3.9dBi, maximum efficiency of 85% and directivity from 4.0dBi to 5.3dBi.
