  • Patent number: 9711849
    Abstract: An antenna reconfigurable circuit changes patterns of a multiple-antenna system and includes a feed portion which an electrical signal is fed to; a plurality of power distribution links coupled between the feed portion and the antennas to form therebetween paths of transmission of the electrical signal; and switching units disposed at the power distribution links, respectively, to selectively disable or enable the paths. The switching units enable the antennas to change patterns and enhance signal reception quality. Furthermore, the antenna reconfigurable circuits are printed circuits instead of lumped elements and thereby maintain response characteristics, response stability and production yield of the antenna reconfigurable circuits.
