Design of Broadband Implantable Antenna for Biomedical Application

<p>A broadband implantable antenna is presented for the biomedical system applications. The proposed adopts a spiral monopole structure to realize purpose of miniaturization size. total size including biocompatible superstrates 15 × 1.42 mm3 operating frequency at 402 MHz. effects some design parameters on performance are discussed. simulated and measured in skin-mimicking gel show that broad bandwidths 150 MHz (310–460 MHz) 260 (280–540 return loss 10 dB can be achieved covering entire Medical Device Radiocommunications Service (MedRadio) Industrial Scientific (ISM, 433–438 bands, respectively. performs an omnidirectional pattern, showing good candidate systems application.</p> <p> </p>
