Summary: | By means of embedding hook‐shaped slots at the edges of the radiating patches for a stacked planar inverted‐F antenna (PIFA), functions of bandwidth enhancement and size reduction can be achieved for suitable use in implantable biotelemetry devices. The designed antenna with overall size of only 8 × 8 × 1.9 mm3 provides a monopole‐like radiation pattern, a radiation efficiency of 0.55%, and a wide −10 dB impedance bandwidth of 122 MHz covering the 402–405 MHz medical‐implant‐communication‐service (MICS) frequency band. Comparing with the reported most compact antennas, the proposed design obtains not only 144% wider bandwidth but also 36% more compact structure size. © 2009 Wiley Periodicals, Inc.
