This paper presents a novel wearable antenna specifically designed for medical applications, offering reliable and efficient communication across Ultra-Wideband (UWB) frequencies. The antenna is optimized for integration into body-worn medical devices, ensuring stable performance even when placed close to the human body. With a foam substrate (dielectric constant 1.07, thickness 2 mm), the antenna is simulated in HFSS, demonstrating broad frequency coverage from 2.05 to 14.7 GHz. It achieves a peak gain of 7.07 dB at 2.5 GHz and a return loss (S11) of -28 dB, ensuring excellent impedance matching and minimal signal loss. The design \(50 \times 38 \times 2 \,{\text{mm}}^{3}\) is ideal for medical monitoring systems, enabling real-time health tracking, body-centric communication, and efficient wireless data transmission in applications like remote patient monitoring, diagnostic wearables, and wireless sensor networks. Its compact size, flexibility, and low-profile nature make it well-suited for continuous use in medical environments.
