A novel design of compact 2.4 GHz microstrip antennas

A novel design of compact 2.4 GHz microstrip antennas, where the radiating patch is designed in fractal configuration, namely, square and pentagon shape respectively, is proposed. The newly designed microstrips provide an optimized patch area resulting into a substantial reduction in size compared to a typical microstrip patch designed at the same frequency of operation. It was found that the characteristics of the novel fractal patch antennas are comparable to the conventional patch antenna, while their gain and radiating efficiency are noticeably improved.
