Abstract

A Gosper curve fractal-based geometry novel Planar Inverted F-antenna (PIFA) antenna has been proposed for implantable biotelemetry applications. The antenna is designed to work inside the human muscle tissue at the MICS band (402–405 MHz). The antenna is composed of two layers of radiating patch stacked together on Rogers RO 3010 substrate with a thickness of 10 mil and a radius of 5 mm. The volumetric size of the proposed antenna is approximately 60 mm3. The initial antenna is designed inside the single layer human muscle tissue and optimized inside the multilayer tissue model. Furthermore, lumped equivalent circuit models, based on Bessel filter function, have been proposed and their results are analogized with the proposed antenna design with an error of 2.1%. The performance of fabricated antenna prototype inside human muscle, mimicking liquid phantom, is matched to a large extent closely to the proposed numerical antenna model that ensures its reliability.
