MEDICAL DEVICE HAVING A MULTI-ELEMENT ANTENNA
First Claim
1. An apparatus comprising:
- a telemetry module; and
an antenna coupled to the telemetry module, the antenna comprising;
a first antenna element that is selectively electrically-coupled to the telemetry module via a feed point;
a second antenna element that is coupled to the first antenna element; and
a tuning network that is selectively tuned in response to an operating environment of the apparatus.

Abstract
Medical devices are provided with multi-element antenna systems that may function to automatically tune the antenna as a function of the operating environment of the medical device. The tuning methodology may incorporate a multi-element antenna having a variable capacitive element on a first of the antenna elements with that antenna element being driven by a second of the antenna elements. In an embodiment, a multi-element antenna system may acquire measurements of predefined criteria and the antenna may be tuned as a function of the measured criteria to optimize operation of the antenna in both reception and transmission of signals. In so doing the antenna impedance can be matched to the transmission line impedance.
