Abstract

The invention provides a multi-beam antenna based on a one-dimensional microwave planar lens and a double-tapered-slot antenna array. The multi-beam antenna is formed by a double-tapered-slot antennaarray (1) and a one-dimensional microwave planar lens (2). The one-dimensional microwave planar lens is formed by four layers of artificial electromagnetic material surfaces (3) where patterns servingas phase shift units (8) are printed, and fixed columns (4). The double-tapered-slot antenna array (1) is formed by double-tapered-slot antenna units (9) and is fixed on an organic glass backboard (7). The antennae are fed by substrate integrated waveguides (6), and can be integrated and connected with other microwave circuits. The one-dimensional microwave planar lens (2) is connected with the organic glass backboard (7) through long nylon support columns (5). The radiation phase center line of the double-tapered-slot antenna array (1) coincides with the focal line of the one-dimensional microwave planar lens (2), and an optimal focusing effect is reached. According to the invention, a high-gain wide-angle spatial scanning function can be achieved, the multi-beam antenna is high in integrated level, simple to manufacture and low in cost.

Description

technical field

[0001] The invention is a high-gain multi-beam antenna formed by loading a microwave lens made of artificial electromagnetic materials in front of the double tapered slot antenna array, which has a large-angle beam scanning function while realizing the high-gain performance of the antenna, and belongs to the field of microwave technology . 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 MIMO (multiple-input multiple-output) technology. This multi-beam antenna can make multiple bea...
