2.3 GHz Rectangular Microstrip Patch Antenna with Elegtromagnetic Band Gap Technique for Body Area Use

Wearable antennas that are small, lightweight, easy to make and others are needed. The Specific Absorption Rate (SAR) of the wearable antenna must be smaller than 1.6. This research designs a rectangular patch wearable antenna with a mushroom-shaped Electromagnetic Band Gap (EBG) operating at a frequency of 2.35 GHz. The addition of EBG to the microstrip antenna aims to increase the gain value of the wearable antenna. In addition, the addition of EBG is also expected to reduce the SAR value. The addition of EBG is proven to increase the gain by 17.5% compared to the antenna without EBG. The SAR value after the addition of EBG is 0.0852 W/Kg, 88.96% smaller than the antenna without EBG.
