Abstract
In this paper the design of a simple rectangular ring slot, co-planar waveguide (CPW) fed, implantable antenna is proposed. By corner perturbation and the introduction of metallic patterns on the superstrate of the antenna, circular polarization (CP) has been achieved. The 10 mm × 10 mm × 0.4 mm dimensions have made the antenna compact and suitable for implantable biomedical application around 2.45 GHz Industrial, Scientific and Medical (ISM) band. Measurement setup comprising of pork slab has been established and the in-vitro analysis of the antenna prototype is carried out by inserting the prototype into it. An axial ratio bandwidth of 10.6% has been achieved for the proposed simple implantable CP antenna.
