Abstract :
A compact stacked implantable antenna for biotelemetry in medical implant communication services band (MICS band: 402-405 MHz) is proposed. Using a stacked planar inverted-F antenna (PIFA) structure can enhance bandwidth and reduce the effect of frequency shift in human tissue giving complex and highly variable characteristics. The antenna looks like one dime (US currency) and has a 7.5 mm radius, 1.9 mm thickness, operating frequency at 402 MHz and a bandwidth of 50 MHz at return loss of 10 dB. A miniature, broadband stacked implantable antenna for biotelemetry with medical devices is provided
