A dual-beam antenna

Abstract

The invention discloses a dual-beam antenna, which comprises a plurality of radiating elements, a reflection plate and feed networks. The radiating elements are fixedly arranged on the reflection plate; the reflection plate comprises a centrosymmetric trench-shaped structure formed by a horizontal plane and bent planes respectively arranged at both sides of the horizontal plane; an angle is set between each bent plane and the horizontal plane of the reflection plate; a left side bent plane and a right side bent plane of the reflection plate are respectively and fixedly provided with a row of the radiating elements along an axial direction; the horizontal plane of the reflection plate is fixedly provided with two rows of the radiating elements along the axial direction; the radiating elements on the bent planes of the reflection plate and the radiating elements located on the horizontal plane of the reflection plate and arranged next to the radiating elements on the bent planes are arranged crosswise; and the radiating elements on the bent planes and the radiating elements located on the horizontal plane of the reflection plate and not arranged neat to the radiating elements on the bent planes are arranged in an aligning manner. The dual-beam antenna disclosed by the invention has the advantages that the overall size is small, the windward side is small, and the practical application risk can be remarkably lowered.

Description

technical field [0001] The invention relates to an outdoor distributed antenna for mobile communication, in particular to a high-gain dual-beam antenna for outdoor mobile communication coverage. The invention belongs to the field of communication. Background technique [0002] With the rapid increase of mobile communication users, some areas of the outdoor communication network are facing the pressure of high traffic and high load. In order to enhance the capacity of the antenna system, help operators out of difficulties, and optimize the existing network, domestic and foreign companies have developed new product dual-beam antennas in recent years, which have entered the market as new high-end antenna products. [0003] Dual-beam antenna, also known as split antenna, integrates two dual-polarized antennas in one radome entity. It uses beamforming technology. Compared with ordinary dual-polarized antennas, the gain of dual-beam antennas decreases faster. The overlapping area...

Problems solved by technology

When the downtilt angle is too large, the horizontal pattern will be seriously deformed, resulting in cross-area coverage and affecting the quality of network communication

In addition, it can be seen from the figure that the overall structure of the ordinary high-gain dual-beam antenna has large dimensions in the width and height directions, and the radome should be designed as a special-shaped structure, resulting in a common dual-beam antenna with large volume, heavy overall weight, and large windward surface. A series of disadvantages such as increasing the overall cost and increasing the risk of practical application due to the increase of severe weather
