Beschreibung
This study illustrates the design method for the implementation of electrically multi-layered small implantable antenna for biotelemetry processes. The suggested antenna consists of three layers arranged in a stack, pressed on high permissively, grounded substratum. The deepest layer of the antenna above the ground flat surface contains a meandered construction with a precisely placed T-shaped aperture. The intermediate segment consists of2 U- contoured radiators and an M- contoured metallic part is moreover added on the highest segment for additional enhancement of the radiation efficacy of the antenna. These three stacked layers form a symmetrical closed loop structure resonating on its fundamental resonant design, at 403 MHz, for the Medical Implant Communication Service (MICS) band. A shifted higher system procedure of the similar enclosed loop design, along the negative currents on ground level allowing broad band process, at 2.45 GHz, for the industrialized, scientific, and medical (ISM) band.
