Abstract
A meandered and a spiral stacked circular planar inverted–F antennas (PIFAs) are proposed for integration into head–implantable biomedical devices and wireless biotelemetry in the 402–405 MHz Medical Implant Communications Service (MICS) band. Designs only differ in the patch shape, feed, and shorting pin positions, while emphasis is given on miniaturization and biocompatibility. Phantom–related resonance detuning issues are addressed, and the PIFAs’ radiation performance (radiation pattern, specific absorption rate (SAR) conformance with international guidelines, SAR distribution, and quality of up–link communication with exterior monitoring equipment) is evaluated and compared. Finite Difference Time Domain (FDTD) numerical simulations are performed.
