Abstract The rapid progress in wireless communication technologies has enabled innovative solutions for biomedical monitoring through wearable devices. This project centers on the design, simulation, and evaluation of a human body-worn antenna for biomedical purposes, utilizing CST Studio Suite. The key goal is to develop a compact, efficient, and cost-effective antenna that can seamlessly integrate with wearable medical systems to transmit real-time physiological data such as heart rate, ECG signals, and body temperature. The antenna employs an FR-4 substrate with a dielectric constant of 4.4 and a thickness of 1.6 mm, while copper is used for both the radiating patch and ground plane due to its superior electrical conductivity and mechanical durability.The antenna functions within the 2.4 GHz ISM (Industrial, Scientific, and Medical) frequency band, commonly utilized in Bluetooth and Wi-Fi-based biomedical telemetry systems. The design was modeled and simulated using CST Microwave Studio, where parameters like return loss (S11), VSWR, impedance matching, radiation pattern, and gain were thoroughly analyzed. Simulation outcomes revealed that the designed antenna achieves a return loss below -10 dB, a VSWR under 2, and a consistent radiation pattern, ensuring reliable signal transmission and reception when positioned on or near the human body. Furthermore, antenna dimensions were optimized to minimize the Specific Absorption Rate (SAR) Its straightforward design and low production cost allow easy integration into smart textiles, medical patches, or portable healthcare systems.
