Abstract
An apparatus includes a transmitter and a receiver device, which includes a receiver section and a processing module. The transmitter transmits a high carrier frequency signal. The receiver section includes first and second antennas that have an antenna radiation relationship for receiving the high carrier frequency signal. A receiver module of the receiver section determines first and second signal properties of the received high carrier frequency signal. The processing module determines a position of the receiver device with respect to the transmitter based on the first and second signal properties and maps the position to a coordinate system.
