Abstract

This paper presents a comparison of the performance of two circular patch antennas. The antennas use a natural Taconic RF-60A with and without modification using laminating metal strips as the substrate, respectively. The first and the second antenna are referred to as a conventional patch antenna and an artificial patch antenna. Laminating metal strips at the natural substrate is predictable will change the antenna performances, such as a gain, a bandwidth, and a pattern. The comparison is conducted using an experimental simulation. The artificial patch antenna has some advantages using simulation optimization in such dimensions and antenna parameters. It has a bandwidth of 49.5 MHz or 21.42 % wider than the conventional patch antenna. A return loss at the centre frequency is 2.97 dB or 9.17 % higher than the conventional patch antenna, and a half-power beamwidth is 0.6° or 0.63 % wider than the conventional patch antenna. Although the artificial patch antenna has a gain of 0.68 dB or 13.47 % lower than the conventional patch antenna, to work at the same frequency of 1.8 GHz, the artificial substrate antenna requires an area of 40.67% smaller than the conventional substrate antenna. From these results, the artificial antenna has a good potential in miniaturizing the patch antenna device size.
