Problems solved by technology

[0003] At present, each phase shifter of the multi-frequency electronically adjustable antenna needs a set of phase shifter phase adjustment system, resulting in the multi-frequency electronically adjustable antenna being too large, heavy, and wind-loaded, which greatly increases the difficulty of antenna installation. And the reliability of the antenna is not guaranteed
Therefore, the current phase adjustment system of the electric antenna can no longer meet the development trend of antenna miniaturization.

Embodiment Construction

[0029] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific embodiments described here are only used to explain the present invention, and do not limit the protection scope of the present invention.

[0030] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of illustration only and are not intended to represent the only embodiments.

Abstract

The invention discloses a tunable antenna phase position regulating system and a drive device thereof. The drive device comprises a first power transmission mechanism and power output mechanisms. Thefirst power transmission mechanism comprises at least one drive assembly. Each drive assembly comprises a drive wheel, an output wheel non-coaxial with the drive wheel and staggered with the drive wheel, and a transmission structure for driving the drive wheel and the output wheel to rotate synchronously. The power output mechanisms correspond to the drive assemblies one by one. Each power outputmechanism comprises a first screw rod, a drive piece in spiral drive connection with the first screw rod, and a first mounting assembly, wherein the first screw rod and the corresponding output wheelare coaxial and rotate synchronously. By means of the tunable antenna phase position regulating system and the drive device thereof, a phase position regulation drive structure of a phase shifter of amulti-frequency-band base station antenna can be greatly simplified, the arrangement mode of the phase shifter is more flexible, and development of antenna miniaturization is facilitated.

Description

technical field [0001] The invention relates to the technical field of communication equipment, in particular to a phase adjustment system of an electric adjustable antenna and a transmission device thereof. Background technique [0002] In current base station antennas, there are mainly two methods of downtilt adjustment: mechanical downtilt and electric downtilt. The principle of ESC downtilt is to change the phase of the collinear array antenna oscillator by changing the phase of the phase shifter, change the amplitude of the vertical component and the horizontal component, and change the field strength of the composite component, so that the vertical direction of the antenna The sex chart is tilted downward. As the frequency bands of mobile communications continue to increase, operators have fewer relative site resources, making multi-frequency electric adjustable antennas more and more widely used. [0003] At present, each phase shifter of the multi-frequency electro...
