  • Publication number: 20100283703
    Abstract: A high-gain multi-polarization antenna array module includes an antenna array and a plurality of Butler matrixes. The antenna array includes four antennas, and each antenna includes two feed portions. Each Butler matrix includes four 90° hybrid couplers, two phase shifters, four input ports, and four output ports, and the four output ports are respectively electrically connected to the four different antennas. The antenna array module integrates multi-polarization array antennas and base station antennas generating beam forming by using the Butler matrixes, such that beam shapes generated by the antenna array may be deflected according to a set specific angle, thereby greatly improving receiving quality of the antennas.

  • Publication number: 20100149063
    Abstract: A dual-frequency antenna includes a substrate, a ground layer, a plurality of signal feed portions, at least one first radiation portion, a plurality of second radiation portions, a plurality of first signal transmission lines, a plurality of second signal transmission lines, a plurality of first filters, and a plurality of second filters. The signal feed portions are disposed between the first radiation portions and the second radiation portions that are disposed on the first surface of the substrate in a staggered manner. The first signal transmission lines and the second signal transmission lines are respectively used to connect the signal feed portions with the first radiation portions and the second radiation portions. The first filters and the second filters are respectively disposed on the first signal transmission lines and the second signal transmission lines. The dual-frequency antenna is applicable for providing broadband and high gain features.
