A Triple band microstrip slot Antenna for S band &C band Applications

This paper presents a compact design and analysis of microstrip patch antenna with triangular and circular slots on the patch surface with meticulous frequency re-configurable tri-band antenna for S, C frequency band applications. The designed antenna is built on FR4 substrate with a loss tangent 0.02. The designed antenna resonates at 2.92, 3.45, and 4.8 GHz. The proposed operational triple-band antenna has more than 90% power transmitting capability in all the operating frequencies. The practical (Antenna measurement setup with Vector Network Analyzer) and modelled (High Frequency Structural simulation) results are in good agreement. A bandwidth enhancement approach has been proposed to adjust or shift the bandwidth of the operating frequency. In terms of radiation properties, the performance of the developed antenna was evaluated using its return loss, bandwidth, and signal power transmitting percent.
