Abstract

In this paper, a compact, circularly polarized printed monopole antenna is proposed at ISM band (2.4-2.48 GHz) for biotelemetry and implantable applications. The proposed antenna possesses a small dimension (10×10×0.3 mm³) and simple microstrip feeding structure. The circular polarization is easily achieved by introducing an ``L'' shape stub at the ground plane in ISM. The simulated 10 dB impedance bandwidth is around 13.87%, and 3 dB AR bandwidth is around 5.3%. The effect of different body phantoms is discussed to evaluate the sensitivity of the proposed antenna. The simulated peak gain of the proposed antenna is about -7.79 dBi across the operating band. The SAR analysis of the antenna configuration has also been studied.
