Abstract

A comparison between rectangular microstrip patch and C-shaped patch antennas are proposed in this paper for wireless local area networks (WLANs) applications operating at the frequency band of 5.2 GHz. The rectangular patch antenna has a return loss of -40.951 dB and bandwidth of 7.9% at 5.2 GHz. The patch antenna has an Omni-directional radiation pattern with maximum gain of 6.5 dBi. The C-shaped patch antenna has shown a bandwidth improvement of more than 13% at a return loss of -43.859 dB better than -10 dB. Similarly, the C-shaped antenna has shown a size reduction of more than 16% compared to the rectangular microstrip patch antenna. However, the antenna’s radiation pattern is more to unidirectional pattern with reduced gain of 4.830 dBi compared to the rectangular microstrip patch antenna. Both antennas were printed on a FR4 substrate with dielectric constant of 4.7. The simulated results were verified through measurement in which a good agreement between the simulated and measured result were documented.
