Abstract
An radio frequency antenna assembly is provided for a medical device such as one capable of being implanted into a patient. The antenna assembly includes a plurality of antennas, each oriented to receive a radio frequency signal propagating along a different axis. This facilitates reception of the radio frequency signal regardless of the orientation of its propagation axis to the medical device. In other cases, the radio frequency signal has a plurality of components, each propagating along a different axis, and each antenna of the assembly receives a different one of those components. The individual electrical signals produced in each antenna are additively combined into a single signal having greater strength than each of the individual electrical signals.
