Abstract

The invention provides a multi-frequency narrow-beam antenna array and an antenna, and relates to the technical field of mobile communication. The multi-frequency narrow-beam antenna array comprises four columns of high-frequency arrays, wherein any two columns of the high-frequency arrays are provided with combiners at the input ends of radiation units respectively; each combiner is used for separating frequency signals of two different frequency bands from the corresponding high-frequency array, and three different frequency bands exist in the frequency signals separated by the two columns of high-frequency arrays by the combiners, wherein the two columns of the high-frequency arrays are combined by the combiners to generate same-frequency-band frequency signals which are combined to form a first high-frequency narrow-beam array; and a second high-frequency narrow-beam array and a third high-frequency narrow-beam array are formed by combining the frequency signals of two different frequency bands generated in the combining mode with the two columns of high-frequency arrays without the combiner in a one-to-one mode. According to the multi-frequency narrow-beam antenna array provided by the invention, combining is performed firstly and then merging is carried out, and the high-frequency narrow-beam arrays can achieve excellent wave width convergence and excellent electrical performance by flexibly deploying the column spacing between two adjacent columns.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of mobile communications, and in particular to a multi-frequency narrow-beam antenna array and an antenna. Background technique [0002] With the continuous optimization and upgrading of mobile communication networks and the continuous advancement of high-speed rail construction, operators are increasingly paying more attention to high-speed rail network coverage scenarios, and the most suitable antenna for high-speed rail network coverage is a narrow beam antenna. Common narrow-beam antennas are mostly single-band or purely high-frequency or purely low-frequency, which is neither in line with the construction idea of ​​multi-system co-construction antenna, but also wastes high-speed rail station resources to a certain extent. [0003] At present, when the multi-band narrow beam antenna array uses four columns of arrays to synthesize three columns of narrow beam arrays, the general tech...
