DUAL BAND FSS FOR BIOMEDICAL APPLICATIONS

Abstract: Biomedical applications require efficient wireless communication systems, particularly in the ISM band (2.4-2.48 GHz), for applications such as patient monitoring and implantable medical devices. In this paper, we propose a dual-band Frequency Selective Surface (FSS) integrated microstrip patch antenna to enhance the gain and bandwidth while minimizing interference. The antenna is designed using a rectangular patch configuration and optimized for biomedical applications. CST Microwave Studio is used for design simulations, evaluating return loss, gain, radiation patterns, and bandwidth performance. The fabricated prototype is measured using a Vector Network Analyzer (VNA) to validate the simulation results. The proposed antenna demonstrates improved performance, making it a suitable candidate for wireless biomedical applications.
