METHOD AND APPARATUS FOR BEAMFORMING

摘要

The present invention relates to a wireless communications system. An antenna apparatus for the wireless communications system comprises: a base; a plurality of Yagi-Uda antenna modules which are arranged in a fixed array on the base; a plurality of floating metal modules which are installed on the top of the Yagi-Uda antenna modules and are selectively connected to the corresponding Yagi-Uda antenna module among the Yagi-Uda antenna modules; a switching device which allows selective switching of the floating metal modules and the Yagi-Uda antenna modules; and a controller which controls the Yagi-Uda antenna modules to have the directivity in a desired direction by selectively switching the switching device.
