    摘要： A method includes: determining a reference direction for orientation; when a first device rotates around an obstruction, receiving a wireless signal sent by a second device, and obtaining a link quality parameter value according to the received wireless signal; determining a position having greatest shadow fading of the first device according to the obtained link quality parameter value, and using a pointing direction of the position having greatest shadow fading of the first device as a first pointing direction; and determining, according to an included angle θ1 between the reference direction and the first pointing direction and an included angle θ2 between the reference direction and a second pointing direction, a direction in which the second device is located, where the second pointing direction is a pointing direction of the first device.

    摘要： An antenna apparatus for determining the position of a radio-frequency transponder is provided, comprising a phased array of antennas enabled to transmit and receive power at a given frequency for communicating with a radio frequency (RF) transponder, the phased array being movable; and a phase shifter for providing a phase shift to at least one antenna of the phased array to provide a minima in a main radiated lobe of the phased array, such that when the phased array is moved from a first position, for detecting the RF transponder via the main radiated lobe, to a second position, where a signal from the RF transponder is minimized, a position of the RF transponder determined to be along an axis of the minima in the second position.
