Embodiment Construction

[0027] In the embodiment of the present application, the multi-beam antenna array provided mainly designs two different antenna sub-arrays in the multi-beam antenna array, wherein the multi-beam antenna array includes at least one first antenna sub-array and at least one second antenna In the sub-array, the first antenna sub-array includes a plurality of first radiating units arranged in a square grid, and the second antenna sub-array includes a plurality of second radiating units arranged in a triangular grid . If the multi-beam antenna array only uses the first antenna sub-array, the first side lobe level of the antenna is low and the second side-lobe level is high; if the multi-beam antenna array uses the second antenna sub-array alone, its horizontal plane The first sidelobe level is high and the second sidelobe level is low. Through the mixing of two antenna sub-arrays, the horizontal plane sidelobe level value of the multi-beam antenna array takes the average value of t...

Abstract

The invention discloses a multi-beam antenna array and a multi-beam antenna. The multi-beam antenna array comprises at least one first antenna sub-array and at least one second antenna sub-array, wherein the first antenna sub-array comprises a plurality of first radiation units which are arrayed in a square grid way; and the second antenna sub-array comprises a plurality of second radiation units which are arrayed in a triangular grid way. The first antenna sub-array arrayed in the square grid way and the second antenna sub-array arrayed in the triangular grid way are mixed in the same multi-beam antenna array, so that the index of the sidelobe level of the horizontal plane of the multi-beam antenna can be effectively optimized.

Description

technical field [0001] The present application relates to antenna technology, in particular to a multi-beam antenna array and a multi-beam antenna. Background technique [0002] With the development of mobile communication, users have higher and higher requirements for the capacity of the communication system; an effective way to improve the system capacity is to use multi-beam antennas for antennas. Generally speaking, multi-beam antennas usually include beamforming networks and The antenna array connected to the network, beamforming network, a typical application structure is a Butler matrix. The radiating elements in the antenna array are arranged in a square grid, that is, they are not arranged in parallel. [0003] Antenna arrays arranged in a square grid in the prior art have the problem of unsatisfactory sidelobe levels in the horizontal plane. Contents of the invention [0004] The invention provides a multi-beam antenna array and a multi-beam antenna to optimize...
