This work presents the design and Biocompatibility analysis of implantable antenna in bio-fluid environment for Biomedical communication applications. The antennae’s topographical structure appears the Yin-Yang symbol and was developed on natural jute felt based material. The developed prototype has a compact dimension of 20×16×1.5 mm³. The antennas implantability was validated under vigorous testing in bio fluids such as goat blood and plasma and also in the synthetic biofluids such as Simulated body fluid and mediums such as D-MEM. In normal operational conditions the developed antenna functional frequencies are 3.5, 4.9 and 5.8 GHz in the Biomedical and ISM application ranges. While assessing its implantability in bio fluids it was observed that the proposed model functions in above said frequency band applications with some minor variations. Similar observations were also made while testing it under in-vitro analysis in synthetic biofluids. The proposed implantable device biocompatibility and lifetime analysis in the biofluids was done in the electrochemical workstation. The observations from the corrosion analysis found that the device has a safe biocompatibility for operating in the implantable conditions.
