Embodiment Construction

[0027] The technical solution of the present invention will be further introduced below in combination with specific implementation methods and accompanying drawings.

[0028] This specific embodiment discloses a folded reflectarray multi-beam antenna with a wide scanning angle, such as figure 1 As shown, there are three subfolding reflectarray multi-beam antennas, which are the left-reflecting reflectarray antenna 1 on the left, the orthographic reflecting array antenna 2 in the middle, and the right-reflecting reflectarray antenna on the right. 3.

[0029] The three sub-folded reflectarray multi-beam antennas all include a polarization grid and a reflector array. The polarization grid is made by printing metal strips at fixed intervals on a single-layer printed board. The reflector array is made by a three-layer metal layer It is made of double-layer printed boards. Among the three metal layers, the top metal layer prints the radiation patch and the reflector patch of the f...

Abstract

The present invention discloses a foldable reflective array multi-beam antenna with a wide scanning angle. The antenna comprises three sub foldable reflective array multi-beam antennas consisting of aleft-reflection foldable reflective array antenna located at a left side, a front-reflection foldable reflective array antenna located at the middle portion and a right-reflection foldable reflectivearray antenna located at the right side. The foldable reflective array multi-beam antenna achieves functions such as space diversity, frequency reuse and the like, is large in high-gain wave beam coverage angle range, overcomes defects of a traditional antenna with a low large-coverage angle antenna gain and a small high-gain antenna coverage angle, has characteristics of a low plane surface, a high gain, a high integration level, easy manufacturing and low cost, can perform space scanning in a condition of reducing the number of radio frequency channels and can flexibly close corresponding radio frequency channels when a corresponding space angle does not need to work to achieve a purpose of energy saving; and moreover, a substrate benefiting an integration microwave circuit and variousmicrowave switching devices is employed to integrate waveguide feed to facilitate using of the foldable reflective array multi-beam antenna on various communication devices.

Description

technical field [0001] The invention relates to the field of antennas, in particular to a folded reflection array multi-beam antenna with a wide scanning angle. Background technique [0002] With the explosive growth of data volume in wireless communication, in order to increase the bandwidth of data transmission, it is necessary to use millimeter wave communication technology. In order to improve the signal-to-interference-noise ratio of the system, reduce the Doppler effect, and improve data security, it is necessary to use a high-gain millimeter-wave antenna. In order to search for links, a high-gain multi-beam antenna with a certain spatial coverage becomes the core part of massive multiple-input multiple-output (MIMO) technology. This multi-beam antenna can make multiple beams exist simultaneously and work independently, which can improve frequency reuse and system capacity. There are three common design methods for multi-beam antennas. One is to realize multiple beam...
