    摘要： A vertically interleaved in-building distributed antenna system is described. The in-building distributed antenna system includes a multiple-input and multiple-output (MIMO) radio. The MIMO radio includes a first branch connector and a second branch connector. The in-building distributed antenna system further includes a first branch transport medium coupled to the first branch connector and a second branch transport medium coupled to the second branch connector. The in-building distributed antenna system further includes a plurality of antennas. The plurality of antennas includes one or more first branch antennas coupled to the first branch transport medium and one or more second branch antennas coupled to the second branch transport medium. The first branch antennas are vertically interleaved with the second branch antennas in the structure.

    摘要： A phase shifter has a chamber with a holding space, a first feeder unit and a second feeder unit at the sides of the holding space, and at least one reversely configured electric regulation unit. The regulation unit contains a first coupling set with a movable and a fixed coupling, and a second coupling set with a movable and a fixed coupling. A sync linkage mechanism is used to link the respective movable couplings. A push-pull unit is linked to a driven connection of the sync linkage mechanism. A cover plate seals the holding space. The phase shifter configuration makes it possible to reduce markedly the volume and space of the phase shifter, cut down the manufacturing cost and improve the mating accuracy with higher applicability.
