Abstract

A device includes a housing, a radio-frequency (RF) antenna, a ground plane, an inductive telemetry antenna, and a processing module. The RF antenna is associated with the housing. The ground plane of the RF antenna is within the housing. The inductive telemetry antenna is within the housing and is disposed over a portion of the ground plane. The processing module is within the housing and is configured to communicate with a medical device using at least one of the RF antenna and the inductive telemetry antenna.
