Abstract

A body‐implantable miniaturized and broadband stacked antenna suitable for biotelemetry communication is proposed. By properly arranging a rectangular three‐layer slotted patch structure, the designed antenna with only 10 × 10 × 1.9 mm^3^ can provide a −10 dB impedance bandwidth of 50 MHz in the 402–405 MHz medical‐implant‐communication‐service frequency band. When compared with the reported most compact antenna, the proposed design achieves not only a more monopole‐like radiation pattern with a double‐radiation efficiency of 0.61% but also a size reduction of 43%. © 2008 Wiley Periodicals, Inc. Microwave Opt Technol Lett 50: 2407–2409, 2008; Published online in Wiley InterScience (www.interscience.wiley.com). DOI 10.1002/mop.23649
