Implantable Slot Antenna for Biomedical Application
Keywords:CPW, CPW fed antenna, implantable antenna, SAR
A compact implantable coplanar waveguide (CPW) fed slot antenna for biomedical application is presented in this paper. Biocompatible material Poly (methylmethacrylate) (PMMA) is coated on the proposed antenna to make it suitable for implantation. The performance parameters of the antenna are measured in terms of the reflection coefficient by immersing the fabricated antenna in a liquid phantom. The proposed antenna covers the complete ISM band (2.4 GHz – 2.5 GHz). In addition, specific absorption rate (SAR) is also estimated which indicates the antenna meets the required safety regulations.
