Design of Microstrip Patch Antenna For Ka-band and Comparison of The Return Loss With Circular Patch Antenna

In this paper an innovative microstrip patch antenna is designed to enhance the return loss. This work presents the comparative analysis of the return loss enhancement between the microstrip patch antenna and circular patch antenna. Materials and methods: The return loss of proposed microstrip patch antenna was compared to circular patch antenna in High-frequency structure simulator environment. The sample size estimation is done using the G Power statistical tool with probability of 80% and the total sample size of the research is 20 and consists of two groups i.e for each group 10 samples. From the SPSS analysis the significance is obtained (0.039) which is less than 0.05. Results: The return loss is improved for -40.56 in the proposed innovative microstrip patch antenna in ka-band frequency range compared to circular patch antenna (−12.59 dB). Conclusion: Within the limits of this study, the proposed microstrip patch antenna attained higher return loss in Ka-band. The results are verified using the HFSS modeling.
