In this article, a miniaturized circular planar inverted‐F antenna (PIFA) is proposed for biomedical applications, operating in Medical Device Radiocommunications Service (MedRadio; 401‐406 MHz) band and Industrial Scientific and Medical (ISM; 2.4‐2.4835 GHz) band. It consists of a U‐shaped patch on top layer, a circular ground on bottom layer, and a shorting pin connecting two layers. By adding two sets of open‐end slots in the ground, dual‐band performance of the proposed antenna is achieved with compact size. Measurement result shows that a wide bandwidth of 41%, ranging from 345 to 510 MHz, can be achieved in MedRadio band, and a wide bandwidth of 27.8%, ranging from 1.92 to 2.60 GHz, can be achieved in ISM band.
