Abstract
Systems, methods and devices facilitating wireless communication with a medical device employ an antenna that provides for increased efficiency, broader bandwidth, and/or improved impedance matching characteristics. In some cases, this antenna is an inverted-f antenna, and in one particular case, the antenna is a non-planar inverted-f antenna. In some cases, the antenna is disposed within a dielectric housing extending along a portion of the side of the medical device.
