Abstract

An embodiment of the invention provides an antenna array and an antenna device. The antenna array comprises at least two transmitting unit sub-arrays; the two adjacent transmitting unit sub-arrays are arranged in parallel; each transmitting unit sub-array comprises a plurality of high-frequency vibrators and at least two low-frequency vibrators; the high-frequency vibrators in the two adjacent transmitting unit sub-arrays are arranged in a staggered way; and the low-frequency vibrators in the two adjacent transmitting unit sub-arrays are arranged in the shape like a triangular mesh. The antenna device employing the antenna array further comprises a reflecting plate. According to the antenna array and the antenna device disclosed by the invention, interference between the high-frequency vibrators is reduced by increase of the distance between the high-frequency vibrators in the two adjacent columns of transmitting unit sub-arrays, consequently, the performance of an antenna is improved greatly.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of communications, and in particular, to an antenna array and an antenna device for communications. Background technique [0002] Antenna is an indispensable part of mobile communication equipment. The performance of base station antenna in mobile communication directly affects the quality of communication. With the continuous improvement of mobile communication technology, users' demand for high-speed data services is increasing, and the types of user needs are becoming more and more diverse. Therefore, modern mobile communication is developing in the direction of multi-frequency and multi-mode. [0003] The multi-frequency multi-mode base station antenna must contain multiple antenna transmitting unit sub-arrays that can work in different frequency bands in the same antenna, and the limited installation space limits the arrangement space and the number of antenna sub-arrays in differe...
