Abstract

The invention provides a miniaturized Yagi-Uda antenna array for mobile communication. The excitation and matching can be realized by adopting a series feeding structure. The miniaturized Yagi-Uda antenna array comprises an excited dipole unit, a reflector parasitic dipole unit, a director parasitic dipole unit and a series feeding structure, wherein one side of the series feeding structure is connected with the excited dipole unit and the reflector parasitic dipole unit, and the other side of the series feeding structure is connected with the director parasitic dipole unit. The miniaturized Yagi-Uda antenna array provided by the invention has the beneficial effects of adjusting an operating frequency and being good in directionality of a directional diagram in the frequency; furthermore, the miniaturized Yagi-Uda antenna array is good in anti-jamming effectiveness, stable in property and large in signal capacity.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a miniaturized Yagi-Uda antenna array for mobile communication. Background technique [0002] With the rapid development of mobile communication technology and the sharp increase of mobile communication traffic, the coverage area of ​​mobile communication network is constantly expanding and perfecting. become more and more important. [0003] The traditional Yagi-Uda antenna uses three independent dipole arrays to form a directional high-gain communication, but the size is relatively large. Contents of the invention [0004] This application proposes a miniaturized Yagi-Uda antenna array for mobile communication. The working frequency band of the Yagi-Uda antenna can be adjusted, and the direction diagram in the frequency band is good; the anti-interference effect is good, the performance is stable, and the signal capacity is large. . [0005] In order to solv...
