Abstract
A system for enabling telemetry in implantable medical devices is provided. One aspect of this disclosure relates to an implantable medical device having radio-frequency telemetry capabilities. The device includes a housing and electronic circuitry contained within the housing. The device also includes an array of antennas connected to the electronic circuitry. According to various embodiments, the array and circuitry are adapted to facilitate far-field transmission and reception of modulated radio-frequency energy at one or more specified carrier frequencies. Individual antenna elements in the array are connected simultaneously or in a mutually exclusive manner to electronic circuitry having a single transmit/receive antenna port using a switch, according to various embodiments. Individual antenna element geometries are sized to optimize individual antennas each for a different range of operating frequencies, according to various embodiments. Other aspects and embodiments are provided herein.
