Implantable antenna for biomedical application

In today’s world the demand for biomedical telemetry is increasing day by day. The idea we are putting forward is an ‘Implantable antenna for biomedical application’. Miniaturization is the major concern for implantable antennas in biomedical application. The major issue with miniaturization is the degradation of various antenna parameters. In order to meet these limitation several techniques were employed to achieve miniaturization in this paper, viz, reducing the antenna dimension, inducing irregularity in the patch, inclusion of wing and circular patch and addition of Rogers RT-Duroid. In the proposed idea we are evaluating the two different cases of the antenna, one without wing and circular patch and the other with wing and circular patch, using the HFSS software .For biomedical applications the United States Federal communication commission has assigned the MICS band whose frequency ranges from 402-405MHZ.We are using the upper C band for the operation of implantable antenna which is higher than the MICS band in order to increase the bit rate. The resultant antenna has a dimension of 14.64×13.06×0.376〖mm〗^3with maximum return loss of -34.1db.
