Compact zeroth-order resonance antenna for implantable biomedical service applications

초록

An implantable zeroth-order resonance (ZOR) antenna is proposed. By using chip inductors, an epsilon negative ZOR was generated, while achieving an extremely compact antenna size. The antenna has the overall dimensions of 0.021 lambda(0) x 0.017 lambda(0) x 0.002 lambda(0) at the Medical Implantable Communication Service (MICS) band (402-405 MHz) and the 10 dB return loss bandwidth is 2.2% ranging from 400 to 409 MHz. Furthermore, the performance of the proposed antenna is insensitive to the electrical properties of the human body by virtue of the ZOR phenomenon.
