Abstract :
This paper presents the design of a 2.4 GHz antenna and a BAW filter for cardiac implants in the ISM band. These components are both sensitive to their environment. The antenna modélisation in human body is presented in order to characterize its impedance. The BAW filter connection to a substrate modifies its impedance, so the link between the two components is the key of the Radio-Frequency transmission. The antenna-filter exhibits a Standing Wave Ratio better than 2 and a maximum insertion loss of 5.6 dB in the 2.4-2.48 GHz frequency band.
