Planar monopole antenna with offset square split ring resonator

A low cost, low profile dual band metamaterial monopole antenna is proposed in this paper. These bands are achieved when a Square Split Ring Resonator (S-SRR) is added on the ground plane; a narrow band covering WiMAX and standard ultrawideband (UWB) with a patch antenna dimension of 10.17 × 15 mm
²
. In order to realize the bandwidth enhancement, parametric studies of the S-SRR and gaps position were performed. The antenna design was performed on the low cost FR4 substrate using CST Microwave Studio. The proposed antenna is suitable for UWB systems covering WLAN/WiMAX for high data rate, interference mitigation and signal quality improvement.
