Document Type and Number:
WIPO Patent Application WO/2011/102522
Kind Code:
A1
Abstract:
Disclosed is a phased array antenna such that the accuracy in phase correction is improved. An antenna is provided with a detection unit (40) for detecting the phase of arrival of a pilot signal in each antenna panel, on the basis of the pilot signal and a reference signal commonly transmitted to respective antenna panels; a position specification unit (51) for specifying positions of respective antenna panels with respect to a reference panel set as a reference antenna panel among the plurality of antenna panels, on the basis of the phase of arrival and the angle of arrival, which is formed by the direction of arrival of the pilot signal and the antenna panel; and a phase shifting amount determination unit (52) for determining respective phase shifting amounts of signals emitted from respective antenna elements, on the basis of position information of the antenna panel specified by the position specification unit (51).
