DIVERSITY ANTENNA AND METHOD FOR CONTROLLING THE SAME

摘要

A diversity antenna system of the present invention includes: two antennas of different directionality, the two antennas generating two signals; a synthesizing means for generating a synthesized signal by synthesizing the two signals; a selection means for selecting either one selected from the group consisting of the two signals and the synthesized signal; and a selection controlling means for controlling the selection means. When the intensities of the two signals are not higher than a predetermined value, the selection controlling means controls the selection means such that the selection means fixedly selects the synthesized signal. According to the diversity antenna, excellent receptive conditions can be obtained even in weak electric fields.
