Triple band monopole antenna for WLAN and WIMAX applications

Abstract

A novel triple band monopole antenna is proposed in this paper. By introducing an E-Shaped patch on the top of the substrate and an inverted L-Shape slit in the infinite ground plane, circular polarization is realized to minimize the losses. It can operate at the frequency of 2.4 GHz, 3.3 GHz and 5.2 GHz for WLAN a/g and WIMAX applications. The dimension of the proposed antenna is relatively small (40 × 45mm2) and it can operate over the frequency range of 2.10-2.85 GHz, 3.1-3.65 GHz and 4.95-5.80 GHz. The simulated results obtained from HFSS 13.0 software and measured results from Agilent network analyser tool shows that the designed antenna performs the triple band operation.
