Design of Circular Microstrip Patch Antenna with Improved Return Loss at 35.2 GHz and Compare with the Existing 5G Antenna

In this work, a novel circular microstrip patch antenna with reduced return loss at 35.2 GHz is compared with 5G antenna. With this research, the designs are presented based on the novel circular microstrip patch antenna which is made up of a circular structure that is built on a commercially available Rogers TMM 10i substrate material having a 1.6 mm thickness and compared with FR4. There were 20 samples in each group. The structure was simulated using HFSS 13.0. G power and significance value is calculated as 0.8 and p < 0.05. Results: According to simulation and experiment results, antenna return loss is decreased to -14.21 dB at 35.2 GHz. The Ansoft HFSS version 15.0 software was used to design this antenna and analyse its performance. Significant RF performance value p < 0.05 is obtained. Conclusion: The result shows that the antenna return loss has been minimized. It is more significant since the p value is less than 0.05.
