Abstract

The invention discloses a folded tuned antenna with rotating and gradual changes. The invention includes a radiator metal layer, a rotatable folded metal assembly, a coaxial line and a rotating drive mechanism; the radiator metal layer is fixedly installed directly above the rotatable folded metal assembly, and after the radiator metal layer is connected to the coaxial line For power feeding, the output end of the rotation drive mechanism is connected to the bottom surface of the rotatable wrinkled metal assembly, and the rotation drive mechanism controls the rotation of the rotatable wrinkled metal assembly. In the present invention, the structure of the radiator is fixed, and the adjustment of the radiation characteristics is realized by adjusting the metal ground mechanically. It can be used for antenna working frequency adjustment and correction, antenna and antenna array beam pointing adjustment and other functions. The mechanism is simple, the adjustment flexibility is good, and it can carry The high-power antenna signal is an antenna design that can be applied to application scenarios that require high power and adjustable antenna parameters, such as 5G base stations.

Description

technical field [0001] The invention belongs to the field of electronic technology and relates to a tunable low-profile antenna, in particular to a tunable antenna with folds that rotate and gradually change. Background technique [0002] With the development of wireless communication, reconfigurable antennas have attracted people's attention due to their ability to implement multiple functions on one antenna. In the microwave frequency band, the antenna performance can usually be adjusted by means of electrical adjustment and mechanical adjustment. The design of adjustable antenna can be realized by adding adjustable electrical components in the radiation mechanism, such as varactor diodes and so on. [0003] For low-profile antennas, in addition to the design of the radiator mechanism, some designs to improve the performance of the antenna through the ground plane mechanism have gradually appeared. Many periodic mechanisms are used in the design of the antenna ground plan...
