Abstract
An immobilizer device is configured for communicating with a base station. The immobilizer device includes an antenna circuit including three orthogonally-oriented antennas configured to receive a signal from a field generated by a base station. A power circuit is configured to draw power via the field on each of the antennas, and a communications circuit is configured to communicate with the base station via any of the antennas. The strength of the signals received via the antennas is evaluated and used to select one of the antennas for use in data communications and, if appropriate, as a power supply.
