Embodiment Construction

[0023] 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.

[0024] It should be noted that when an element is referred to as being “disposed on” or “fixed on” another element, it may be directly on another element or there may be an intervening element. When an element is referred to as being "fixed on" another element, or "fixedly connected" to another element, it may be detachably fixed or non-detachably fixed therebetween. When an element is referred to as being "connected" or "rotatably connected" to another element, it can be directly connected to the other element or intervening elements may also be pres...

Abstract

The invention discloses an antenna and a phase shifting device. The phase shifting device comprises a first dielectric component and a second dielectric component which are relatively arranged; a spiral transmission belt line is arranged on the first dielectric component; a first through groove is formed in the second dielectric component, injection of the contour of the first through groove on the first dielectric component fall onto the transmission belt line in the direction from the second dielectric component to the first dielectric component, and the second dielectric member can rotate axially around the second dielectric member relative to the first dielectric member. The phase shifting device is simple in structure and small in volume, and the requirement of miniaturization is met;in this way, the antenna adopting the phase shifting device meets the development requirement of miniaturization.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to an antenna and a phase shifting device thereof. Background technique [0002] With the continuous development of the economy and the continuous expansion of the activity area, the coverage of mobile communication technology is also expanding. Along with the increasingly stringent requirements for mobile communication technology, the requirements for antenna performance are also constantly improving. [0003] In a traditional antenna, the phase shifter is mainly moved in a straight line or in an arc to change the phase shift amount so as to adjust the tilt angle of the antenna. The structure of the traditional phase shifting device is relatively complicated, which will occupy more work space, which is not conducive to the development trend of miniaturization of the antenna. Contents of the invention [0004] Based on this, an antenna and its phase-shifting device a...
