ABSTRACT
Abstract: The microstrip patch antennas offered in this research exposure was designed and simulated on three different substrate materials to investigate its performance for its employment in future higher frequencies wireless applications in general and 5G cellular applications in particular. In the past, researchers employed different dielectric substrates to analyze microstrip patch antenna in low frequency range. In the presented research work three different dielectric materials were investigated in the higher frequency range starting from 12GHz as the scientists consider these higher frequencies suitable for future wireless mobile applications. Three simple rectangular patch structures were designed on three different insulated substrates including FR-4, Mica and Preperm. The thickness of the Mica was 2.15mm and the thickness of FR-4 was 2mm, while the thickness of the Preperm was reduced to 1.75mm. The parameters of all the three antennas were optimized to demonstrate better results. The results obtained from all the aforementioned structures were compared with one another. Emphasis was made on the bandwidth expansion and improvement on the efficiency. The Patch antenna on Mica substrate demonstrated better results as compared to the antennas on Preperm and FR-4 substrates. Patch antenna on Mica substrate attained huge dual bandwidths of 26.06GHz and 16.16GHz respectively. It attained greater efficiency of 81.88% and a maximum gain of 8.19dBi. Based on the results attained by the antenna on the Mica substrate, it is established that it will be the best antenna for wireless mobile applications at higher frequencies as compared to the remaining two antennas.
