Abstract

A CPW-fed flexible fractal shape circular ring patch (FSCRP) antenna is presented in this paper and operates at ISM band for biomedical applications. The proposed antenna operates at 2.46 GHz both in free space and on a human hand. This antenna functions within a 10 dB impedance bandwidth of 390 MHz (2.38 GHz to 2.77 GHz) in free space and 800 MHz (2.04 GHz to 2.84 GHz) on human hand structure with a reflection coefficient of -33.9 dB and -36.97 dB respectively. The circular shape fractal structure operates the antenna with circular polarization, and a 3 dB axial ratio of 170 MHz (2.4 GHz to 2.57 GHz) has been observed. The proposed antenna can be used in Implantable Medical Devices (IMDs) for biotelemetry applications. The simulated and measured results for the proposed FSCRP antenna are also presented in this paper.
