Supergain array antenna system and method for controlling supergain array antenna

摘要

To provide a super directional gain in a multi-element array antenna. An array antenna comprising a plurality of antenna elements A- 1 -A- 4 spaced at intervals (equal to or less than a quarter of a wavelength) that provides a supergain is used. A weight generator circuit generates weight data in accordance with phase difference and amplitude difference among the antenna elements A- 1 -A- 4 and directivity data of each of the antenna elements A- 1 -A- 4. The generated weight data is used to weight each of the antenna elements A- 1 -A- 4.
