1. A device comprising:
- an antenna;
a parasitic element configured to modify a radiation pattern of the antenna by reflecting energy transmitted from the antenna to increase directional strength of the antenna, wherein the parasitic element has an impedance value that is adjustable, and wherein the radiation pattern of the antenna depends on the impedance value of the parasitic element; and
a telemetry control module configured to;
transmit data to a medical device using the antenna;
receive acknowledgement data from the medical device using the antenna;
determine, based on the acknowledgement data, that the data transmitted to the medical device included errors upon receipt at the medical device, wherein the acknowledgement data is generated by the medical device based on the data transmitted to the medical device, and wherein the acknowledgement data indicates whether the data transmitted to the medical device included errors upon receipt at the medical device; and
adjust the impedance value of the parasitic element associated with the antenna in response to the determination based on the acknowledgement data that the data transmitted to the medical device included errors upon receipt at the medical device to improve subsequent data transfer to the medical device.

Abstract
A device includes an antenna, a parasitic element, and a telemetry control module. The parasitic element modifies a radiation pattern of the antenna. The parasitic element has an impedance value that is adjustable, and the radiation pattern of the antenna depends on the impedance value of the parasitic element. The telemetry control module is configured to transmit data to a medical device using the antenna, receive data from the medical device using the antenna, and detect communication errors using data that is received from the medical device. Additionally, the telemetry control module is configured to adjust the impedance value of the parasitic element in response to detection of communication errors.
