A Wideband Miniaturized Implantable Antenna for Biomedical Application at HBC Band

In this study, a wideband implantable antenna with a small size of 3 cm is designed to operate at Human Body Communication (HBC) band. The proposed implant antenna is realized with two layer of non-equally spaced helical copper foil for dual-resonance frequency band in which -10 dB impedance bandwidth is 15.66 MHz (48.21^%). The miniaturization of the antenna is realized by forming the copper radiation element on two layers of flexible magnetic sheet. Simulation results in a cubic tissue-equivalent phantom demonstrates that the proposed wideband antenna is a useful and capable candidate for high-speed transmission in implant biomedical applications at HBC band.
