Embodiment Construction

[0027] The multi-beam antenna based on the one-dimensional microwave planar lens and the double tapered slot antenna array of the present invention is a multifunctional antenna synthesized by two independent structures. The one-dimensional microwave plane lens is a plane lens composed of four layers of separate artificial electromagnetic material surfaces. The phase-shifting units are printed on the surface of each layer, and these phase-shifting units are arranged in columns, that is, they are arranged continuously in the horizontal direction and arranged differently in the vertical direction according to different phase-shifting requirements. Nylon fixing columns are used between the surfaces of the four layers of artificial electromagnetic materials to maintain the air separation distance to achieve resonance. The double tapered slot antenna line array consists of 16 double tapered slot antenna units linearly arranged in the horizontal direction, and the double tapered slot...

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...
