| 20110001678 | Antenna Array - An antenna array comprises a substrate, radiation conductors, a first transmission network, a second transmission network, support members and a grounding plane. The radiation conductors are symmetrically arranged on the substrate. The first transmission network has a first feeder point and feed arms connected to the radiation conductors, wherein each feed arm of the first transmission network and the radiation conductor connected to the feed arm include an angle of 80-100 degrees. The second transmission network has a second feeder point and feed arms connected to the radiation conductors, wherein each feed arm of the second transmission network and the radiation conductor connected to the feed arm include an angle of 80-100 degrees. The radiation conductors, the first transmission network and the second transmission network are all disposed on an identical surface of the substrate. The support members are used to support the substrate and assembled to the grounding plane. | 01-06-2011 |

| 20080316137 | ANTENNA ARRAY - An antenna array includes five grounding plates, a signal transmission part, two radiation conductors, and a signal feed cable. The first and fifth grounding plates located at the same plane are substantially perpendicular with the second and fourth grounding plates respectively. The second and fourth grounding plates respectively connected to the first and fifth grounding plates extend with the same direction and have two holes or grooves. The third grounding plate connected between the second and fourth grounding plates is substantially perpendicular with the second and fourth grounding plates. The signal transmission part passing through the two holes or grooves is substantially perpendicular with the second and fourth grounding plates. The signal transmission part is connected between the two radiation conductors. The signal feed cable includes a central conductor connected to the signal transmission part and an outer conductor connected to the third grounding plate. | 12-25-2008 |
