Reflection Coefficient Improvement of Leather Substrate Wearable Antenna with Square and Circular Slot compared to Cotton Substrate Antenna

Abstract

Aim: The aim of this research paper is to analyze the wearable square and circular slot antenna using leather substrate in comparison with the wearable square and circular slot antenna using cotton substrate to improve reflection coefficient. Materials and Methods: There were two sampling groups used for this statistical study. Twenty samples were taken from each of two groups. The first group consisted of a square and circular slot antenna on a unique leather substrate, whereas the second group consisted of a similar antenna on a cotton substrate. Twenty individuals were used for the study of the wearable antenna with the enhanced reflection coefficient (Group 1 = 10 and Group 2 = 10), and the numbers were calculated using G-power 0.8, alpha qualities of 0.05 and beta qualities of 0.2, and a 95% confidence interval. Results: In comparison to the −17.51dB reflection coefficient of the cotton substrate antenna, the leather antenna has a reflection value of −25.75dB. The study is statistically significant. Conclusion: Wearable square and circular slot antennas using leather substrate provide better performance in the reflection coefficient parameter at a frequency of 3.7 GHz when compared to wearable square and circular slot antennas using cotton substrate.
