Abstract: The present invention relates to a transmission device for a phase shifter and an actuator device for a phase shifter. The transmission device includes a support, a lead screw nut mechanism and an automatic locking device. The automatic locking device includes a shaft connector rotatably supported on the support and configured to be in transmission connection with a driven connector of a driving device; a locking connector which is in transmission connection with the shaft connector, is in transmission connection with the lead screw, has a locking element and is movable relative to the shaft connector and the lead screw; and a locking spring. When the driven connector is decoupled to the shaft connector, the locking spring biases the locking connector in a first position, in which the locking element engages a counter-locking element on the support.

Abstract: A low frequency band radiating element for a multiple frequency band cellular base station antenna comprises a dipole arm including a radiating portion and a first coupling portion and a dipole leg that includes a leg and a second coupling portion located at one end of the leg. The first coupling portion is removably connected to the second coupling portion.

Abstract: Antennas comprise a reflector and first and second arrays of first radiating elements mounted on the reflector. The antenna further comprises a parasitic element including a metal ring, where the metal ring of the parasitic element is arranged between a first radiating element of the first array and a first radiating element of the second array. The antenna can improve the isolation between adjacent arrays, thereby improving the radiation patterns generated by the arrays.

Abstract: The invention relates to a manual actuating device for a phase shifter of a base station antenna. The device includes a support module having an elongated base body and a first and a second receiving portion which protrude from the base body and are spaced apart in a longitudinal direction of the base body; and a lead screw drive having a lead screw and a nut. The lead screw is rotatably supported in the first and the second receiving portion, and the nut is translationally movably installed on the lead screw. The device also includes an actuator rod connected to the nut and configured to actuate the phase shifter; and a manual operating part connected with the lead screw and configured to manually operate the lead screw to rotate the lead screw. The actuating device is simple and compact in structure and is easy to manufacture and install.

Abstract: The present invention relates to a radiator support for a base station antenna. The radiator support includes a first support part and a second support part that are separate from each other. The first support part is configured to be mounted to extend upwardly from a reflector plate, to extend in part of a height of the feeding stalk, and to bear radially the feeding stalk so as to prevent roll-over of the feeding stalk. The second support part is configured to be mounted adjacent a distal end of the feeding stalk facing away from the reflector plate, and to receive a radiating element. The present invention also relates to a radiator having such radiator support, and a base station antenna having such a radiator. The radiator support according to the present invention has a simple structure, occupies a small structural space and has a favorable versatility.
