Multiband Microstrip Patch Antenna for Microwave Applications

In this paper, we present a fractal shape slot based patch antenna for multiband operations. The fractal shape slot is designed on the rectangular patch and the antenna is fed through a microstrip line. The proposed design and feeding technique allows the antenna to operate at multiple frequencies in the range of 120 GHz. It is demonstrated through simulation that the Return Loss (RL) values occurred at 1.33 GHz, 4.16 GHz, 7 GHz, 9.8 GHz, 12.7 GHz, 15.5 GHz and 18.3 GHz, respectively, having VSWR ≤ 2. It is also observed that the gain of proposed design is higher than the conventional patch antenna. Parametric study is also included to give an overview for the performance of proposed design.
