Abstract :
The study of the implantable antenna performance for an square spiral PIFA miniaturization is presented in this report. The prototypes analyzed operate in the Medical Device Radiocommunications Service (MedRadio) frequency band (401-406 MHz). Three miniaturization techniques are compared to come out with the more suitable method in terms of efficiency and volume. The electromagnetic modeling is based on the finite-difference time-domain method. Low-Temperature Co-fired Ceramic technology is used for the substrate. Results indicate that the 3D structure with the radiator facing the ground plane achieves the best performance in a volume of 200 mm3 for a square spiral PIFA antenna.
