Abstract
Abstract A compact implantable microstrip patch antenna is proposed with small patch size for biotelemetry applications, which works on Industrial, Scientific, and Medical (ISM) (2400.0‐2483.5 MHz) band. Rogers RO Duroid 3010 is used as a substrate as well as superstrate layer of dielectric constant 10.2 and thickness 0.64 mm. The dimensions of antenna are 13.3 × 14.6 mm 2 . The frequency range covered by the antenna is 2.26 to 2.71 GHz with appreciable bandwidth of 18.10% and its resonating frequency is 2.45 GHz at which its return loss is −20.7 dB inside skin. For validation of results, the antenna performance is checked inside in‐vitro solution of skin mimicking liquid. Thus, a miniaturized skin implantable antenna for biotelemetry applications is proposed.
