Comparison of Implantable Antennas for Cardiovascular Patients

摘要

Implantable device cardiac observation (ICDO) such as pacemaker requires communication with medical devices outside the body in order to monitor or control the parameters of the organ it is supporting. Three types of implantable antennas have been investigated to determine their performances on two patient conditions: normal and hyperglycemia. Folded dipole, serpentine microstrip, and waffle-type Planar Inverted-F (PIFA) antennas are operated in the 402-405 MHz, which is medical implant communication services (MICS) band. Detailed analysis of the design issues of the antennas and comparative results of simulations and measurements are presented.
