Human implanted spiral antenna for a 2.45GHz wireless temperature and pressure SAW sensor system

Abstract

In this paper, we presented a new technique to optimize a human implanted spiral antenna for a 2.45 GHz wireless temperature and pressure SAW sensor system. The antenna was designed to especially operate when closely implanted to a human heart. In a homogenous phantom, we have shown that it was possible to simply link the two arms of a traditional dipole to achieve better matching and reduced antennapsilas dimensions.
