Design of bio implantable antenna for in body applications

This paper describes a flexible loop antenna for in-body applications. This antenna works in the Med Radio band(402 MHZ-406 MHZ) which is the standard band for Bio Implantable applications, ISM Bands at 433 MHZ“434.8 MHZ and 902 MHZ-928 MHZ. The antenna is having a size of a 3.5 mm radius and height of 15 mm. The simulated antenna is having a Bandwidth of 228 MHZ (310 MHZ-538 MHZ) at 400 MHZ and 334 MHZ at 1GHZ having a VSWR<;2. The Radiation pattern of this antenna is unidirectional having a gain of -31.7 dBi.
