Abstract
In this paper, a novel design of triple-band inset-fed rectangular micro strip antenna with T-shapeslitloade disproposed for WiMAX, 5.5 GHz WLAN and lower X-band satellite applications is presnted. The proposed antenna consists of rectangular radiating elements with a T-shape slot loaded, which is excited through simple 50Ω in set microstrip feed-line. The antenna configuration is printed on a 40 × 30 × 1.6 mm3 low cost FR-4 dielectric material having permittivity of 4.2 which includes ground plane. To obtain a triple-band operation, a narrow Tshaperectangularslitisembeddedat the top non-radiatingedge of the radiating patch. The proposed antennaresonatesat three frequencies of 3.11, 5.5 and 6.30 GHz with -10 dB impedancebandwidths of BW1= 6 % (2.91-3.05 GHz), BW2= 7.27% (5.34-5.69 GHz) and BW3= 4.14% (6.13-6.41GHz). The simulation results are obtained by utilizing 3D full-wave high frequency structural simulator (HFSS) for comparison with experimental results. Acceptable agreement isobserved between the both experimental and simulation results. The obtained results indicatethat, the propose dantenna shows broadside radiation characteristics a tthree operating frequency bands. Owing to its simple antenna structure and its radiation characteristics, it is highly recommendable for applications at which adequately covers the frequency bands of WiMAX, 5.5 GHz WLAN and X-band lower satellite communication (6-6.5 GHz). The details of antenna designing and results are presented and discussed.
