Design and implementation a multi-circle with star-slots patch antenna structure for on-human body wearable medical devices

This paper looks at the wearable fractal antenna for Wireless Body Area Network (WBAN) applications. This sort of antenna, which operates in the frequency range of (0-10) GHz, is employed in biomedical applications in a safe and appropriate manner. The proposed multi-circle with star-slots patch antenna is designed using a low-cost and widely available (FR-4) substrate, and this antenna has achieved a bandwidth of (3.56-5.76) GHz with a return loss of -53dB. It has a resonance frequency of 4.28 GHz and a SAR of 0.99 Watts per kilogram. This antenna and body phantom were created using CST studio software.
