A serpentine planar inverted-F antenna (PIFA) is designed for Medical Implant Communications Services (MICS) band (401-406MHz) and presented in this paper. Resonance frequency of implantable antenna is generally detuned towards lower frequency due to the proximity effect of high permittivity human tissue.

Abstract
A serpentine planar inverted-F antenna (PIFA) is designed for Medical Implant Communications Services (MICS) band (401-406MHz) and presented in this paper. Resonance frequency of implantable antenna is generally detuned towards lower frequency due to the proximity effect of high permittivity human tissue. In addition, biocompatible coating material on the antenna also leads frequency shifting of the antenna. To overcome this frequency detuning problem, the proposed serpentine PIFA is sealed in a high dielectric constant (Silicon, eps_r=11.9) material. The proposed PIFA antenna is predicted to be functional in MICS band under IEEE standard safety regulation. Gain of the antenna is -33dBi.Pubblicazioni consigliate
