Miniaturized implantable broadband antenna for biotelemetry communication

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 X 10 X 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 old-v a more monopole-like radiation pattern with a double-radiation efficiency of 0.61% but also a size reduction of 43%.
