Abstract :
A microstripline-coupled printed wide-slot antenna with loop loadings is presented for WiMAX/WLAN applications. The proposed compact antenna has a planar size of 38 × 39 mm2. The antenna is comprised of a stepped microstrip feedline along with strip loadings which are coupled to a pair of concentric rectangular loop elements inserted in the center of a slotted ground plane. The slot antenna alone shows wideband S11 performance (2.1-6.8 GHz). By inclusion of the loops, the antenna exhibits a dual-band (2-4 GHz / 5.1-5.95 GHz) operation where undesired bands around 4.5 GHz and 6.1 GHz are rejected, thus covering the assigned bands for WiMAX and WLAN operations. The numerical design results are presented in the paper.
