Abstract

The present invention provides an antenna control method and an antenna device. The method includes (A1) defining a plurality of rough scanning sectors in a signal region; (A2) rotating the antenna to each rough scanning sector to measure a first evaluation signal; (A3) selecting one of the plurality of rough scanning sectors in accordance with the first evaluation signals; (A4) defining a plurality of fine scanning sectors; (A5) rotating the antenna to the plurality of fine scanning sector corresponding to the selected rough scanning sector to measure a second evaluation signal; (A6) selecting one of the plurality of fine scanning sectors in accordance with the second evaluation signals; (A7) rotating the antenna to the selected fine scanning sector.
