Abstract

A compact coplanar waveguide (CPW)-fed ultra-wideband printed circular monopole antenna with band-notch characteristics is presented in this paper. The proposed antenna consists of a split ring resonator (SRR) in the circular patch to achieve a band notched characteristics in the WLAN (5.15-5.825 GHz) band. The predicted VSWR, frequency notch behavior in VSWR, gain and radiation patterns are analyzed. The antenna has an operating impedance bandwidth from 2.77 GHz to 12 GHz, with a band-notched from 5.02 GHz to 5.88 GHz band. VSWR is less than 2 (S11 < -10 dB) over the operating frequency band except band-notch frequency range. The gain variation of this antenna over the ultra-wideband range is 2.55 dBi to 5.28 dBi. In the band-notched region, there is a significant fall in gain.
