Design of Novel Rectangular Patch Microstrip Antenna for Ku Band Applications and Comparison of Gain with Circular Patch Antenna

Abstract

The aim of this work is to design a Novel rectangle shaped microstrip patch antenna with air gap technique in Ku band frequency and comparison with circular patch antenna with gain as parameter. Materials and methods: A total number of 20 samples has been taken by varying frequency. In this design, Epoxy FR4 (relative permittivity 4.4) is used as a substrate material and perfect E material for patch and ground. Since obtained significant value with G power calculation is 80%. Results: Antenna is resonating at a freq of 15.6 GHz with a gain of 4.42 decibels. This antenna has been analyzed and designed for its performance with aid of Ansoft HFSS version 15.0 software. Simulated result shows the significance value is 0.04 ($\mathrm{p} < 0.05$). Conclusion: Based on the analysis, the designed antenna has a higher gain compared to circular patch antenna.
