Based on a planar inverted‐F antenna (PIFA) configuration, two different shaped (meandered and spiral) antennas are designed using finite‐difference time‐domain (FDTD) simulations and measurement results. The antennas are installed on an implantable medical device in a biological‐tissue simulating model. The impedance‐matching and radiation characteristics of two PIFAs are compared in order to observe which shape is more appropriate for wireless communication links of implantable medical devices. Additionally, the effects of the human skin's thickness on the antennas are studied in order to consider medical devices which are implanted in various subcutaneous tissues. © 2006 Wiley Periodicals, Inc.
