Abstract/Description
-
This effort studies the implementation of a biocompatible Planar Inverted-F Antenna (PIF A) for the Medical Instrument Communication System (MICS) frequency band of 402 to 405 MHz for RFID applications. The basic electromagnetic properties of human tissues are investigated at 403 .5 MHz. Then, the radiation characteristics of submerged wire antenna are evaluated in order to approximate the effects of multilayered media on a PIFA's performance. The PIFA is assessed using Ansoft's Finite...

The basic electromagnetic properties of human tissues are investigated at 403 .5 MHz. Then, the radiation characteristics of submerged wire antenna are evaluated in order to approximate the effects of multilayered media on a PIFA's performance. The PIFA is assessed using Ansoft's Finite Element Method based electromagnetic evaluation software, HFSS v.l 0. The electrical parameters of the antenna in relation to the surrounding environment, notably air, silicone capsule, and a three-layered bio-media, are presented. The analysis shows that the resonant frequency as well as the electrical performance of the design is significantly affected by the physical dimensions and the relative permittivity of the dielectric materials covering the antenna.
