On-body communication is a crucial technology, finding applications ranging from healthcare monitoring to IoT connectivity. Using antennas, on-body communication technology exploits specific frequency bands and tailored antenna designs to facilitate efficient data exchange between devices on or near the human body. This study delves into patch antenna designs customized for on-off body communication at 2.4GHz frequencies. As the demand surges for seamless connectivity with diminutive, inconspicuous form factors, an in-depth exploration of antenna design becomes indispensable. The antenna, crafted with FR-4 (a lossy material) possessing a dielectric constant of 4.4, employs copper for the patch and ground layers. Simulation is carried out utilizing the CST Studio Suite, confirming and documenting key antenna parameters: Gain of 5.65dB, bandwidth of 96.8MHz, return loss of -41.83dB, and VSWR of 1.05. Through simulation, a thorough analysis of the antenna's performance in both free space and on the body is conducted, unveiling its exceptional performance in these scenarios. Furthermore, the proposed design optimizations exhibit resilience against environmental factors, making them well-suited for practical on-body communication applications.
