Abstract	A compact ultrawideband implantable antenna for leadless cardiac pacemaker applications is presented. The antenna operates efficiently inside biological tissues and supports ISM, WMTS, and mid-field communication bands. Parametric optimization improves impedance matching and radiation performance, while SAR analysis confirms safe operation within regulatory limits. Link budget analysis and experimental validation using tissue-equivalent phantoms demonstrate reliable communication and good agreement between simulated and measured results.
