Abstract

This paper introduces the design of a 2.45 GHz patch antenna specifically intended for biomedical applications. This compact microstrip-fed antenna comprises a planar radiating patch with a circular configuration, fabricated on a substrate made of polymer resin composite material, measuring 1.6 mm in thickness. To assess how human tissue affects the antenna system, a three-layer human model representing skin, fat, and muscle was meticulously created using CST Microwave Studio. In addition, this research aims to emphasize the suitability of the chosen polymer resin material substrate for examining the antenna's performance. The antenna's performance was assessed in two different scenarios: one in free space and the other using the human body model. In a free-space environment, the antenna resonated at an operational frequency of 2.39 GHz, delivering a noteworthy bandwidth of 610 MHz, spanning from 2.15 GHz to 2.76 GHz. When placed on the human body model, the antenna resonated at 2.4 GHz, demonstrating an even broader bandwidth extending over 1060 MHz, ranging from 2.09 GHz to 3.15 GHz. Remarkably, the antenna achieved a gain exceeding 4.2 dBi and maintained an efficiency exceeding 97% across the entire frequency spectrum. Simulation outcomes further revealed a substantial reduction in the Specific Absorption Rate (SAR) by more than 98%, equivalent to a SAR value of merely 0.024 W/kg.
