Patent ID: 7203469

Claim:
A supergain array antenna system having an array antenna, the array antenna comprising a plurality of antenna elements and having an element interval that provides a supergain, the supergain array antenna system comprising: weight generator means for generating weight data in accordance with each of directivity data for the plurality of antenna elements of said array antenna; and weighting means for using the weight data generated by the weight generator means to weight the plurality of antenna elements of said array antenna, wherein said element interval is equal to or less than a quarter of wavelength of a signal received and/or transmitted, and said weight generator means comprises an element directivity data memory which stores said directivity data, obtained by measuring a phase difference and an amplitude difference between said antenna elements, as directivity patterns indicating an angle with the lateral axis and a directional gain with the longitudinal axis, and a supergain weight generator unit which generates said weight data by referring to the stored directivity data.
