Abstract: An antenna pattern selection method includes a first communication device sending a plurality of packets to a second communication device. Then, the first communication device measures, in each of a plurality of antenna patterns, signal quality of a plurality of acknowledgment frames with which the second communication device separately responds to the plurality of packets, and finally selects a dominant antenna pattern from the plurality of antenna patterns based on signal quality corresponding to each of the plurality of antenna patterns. According to the antenna pattern selection method, when normal communication is not affected, the first communication device may determine, based on signal quality of an acknowledgment frame, whether an antenna pattern used by the first communication device is proper.
