Abstract

Leather antenna also known as wearable antenna is a technology that is being actively developed to improve the quality of daily life for future use. The objective of this project is to design the combination of ring patch antenna and analyze antenna parameters. The features of the proposed antenna should be small, lightweight, flexible, and easily integrated into the human body. Therefore, the antenna proposed in this project is a microstrip antenna in the form of a combination of 5 rings that make up the Olympic logo and uses fabric material as substrate and graphene conductive ink as conductive material with a resonant frequency of 2.47 GHz. For the simulation, Microwave Studio Computer Simulation Technology (CST) software was used to design the proposed antenna to obtain the optimal antenna size before the fabrication process. The simulation result shows that the simulated antenna achieved the return loss of -31.585 dB at 2.47 GHz with a bandwidth 182.64 GHz range from 2.3687 to 2.5507 GHz and VSWR at 1.054. For the measured antenna, the return loss achieved at 2.42 GHz is -21.40 dB with bandwidth 170 GHz ranging from 2.33 to 2.4 GHz and the VSWR achieved at 2.42. The results show that the proposed antenna has good performance in terms of return loss, bandwidth, and VSWR.
