Problems solved by technology

[0003] Striplines often have the following disadvantages: First, the striplines are very long and thin, so they are easily deformed, and sometimes soldering is required between two striplines; secondly, part of the PSN is fixed by screws, while Metal screws will affect the passive intermodulation (PIM) performance of PSN; in addition, the current phase-shifting unit structure of PSN is very complicated, difficult to assemble and rework, and PSN can sometimes include more phase-shifting units, when When the PSN is used for environmental testing, the Antenna Control Unit (ACU) cannot drive the phase shifting device, which causes inconvenience to the use of the PSN and limits the use of the PSN

Abstract

The present invention provides a phase shifting device and an electrically adjustable antenna, wherein the phase shifting device includes: a ground plate; two bottom substrates, which are respectively located on both sides of the ground plate and coupled to the ground plate; two top substrates, They are respectively located on both sides of the two bottom substrates, and each top substrate and each bottom substrate form a phase shifting unit; the pull rod is coupled to the two top substrates and is used to adjust the distance between the two top substrates and the two bottom substrates. The relative sliding of each phase shift unit adjusts the phase of the output signal at the same time. By adopting the technical solution in the present invention, the phase shifting device does not need to use screws during assembly, which improves the PIM performance of the phase shifting device, and has less friction, enabling the ACU to drive the pull rod at low temperature. The phase shifting device has few parts, low cost, and is connected by non-metallic rivets, which is very easy to assemble and rework.

Description

technical field [0001] The present invention generally relates to the field of wireless communication, and more specifically, relates to a phase shifting device for electrically adjustable antennas. Background technique [0002] Electrically adjustable antennas are widely used in wireless transmission. In addition to the radiation unit, the reflector, and the PhaseShifter network (PSN) are an important part of the electronically adjustable antenna. The phase shifter is mainly used in the electronically adjustable antenna to adjust the phase change of the feed network, thereby changing the phase of each or a group of radiating elements, and achieving the purpose of changing the vertical beam inclination or horizontal beam angle. In particular, in the current phase-shifting network PSN, an air stripline is often used to transmit signals, and at the same time, a movable medium is placed under a specific position of the stripline to realize a phase change. [0003] Striplines ...
