Abstract
This research is based on developing a dual-layer microstrip patch antenna for WLAN applications. The target frequency for the desired antenna is 5.2GHz. The overall dimension of the antenna is 36×32×3.2 mm3 .To obtain broad bandwidth and gains, several attempts have been undertaken, such as using different heights of the substrate with the same FR-4 material. The results of the simulations were obtained using the CSTMW software 2018.The antenna's benefits include a simple construction, wideband performance, minimal return loss, and increased gains above conventional designs. Throughout this analysis dielectric Fr-4 substrate was used. Finally, it was found from the analysis compared to the single layer the return loss having-17dB with gain 2.94dB and double layer substrate with equal heights (1.6mm+1.6mm) achieved -36.5dB and having gain 4.48dB. From the analysis this proposed antenna well suited for WLAN applications.
