Embodiment Construction

[0032] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0033] The present invention is a millimeter-wave grid unit type panel array antenna, the structure of which is as follows figure 1 As shown, it includes an array 2 formed by several grid-type antenna units 1, and each grid-type antenna unit has a multi-unit structure.

[0034] like Figure 1 ~ Figure 4 As shown, the array 2 is a planar array, including an H-plane or E-plane planar waveguide power division array.

[0035] like Figure 5 ~ Figure 6 As shown, the 1-point multi-unit structure is a standard cross grid unit.

[0036] like Figure 7 ~ Figure 8 As shown, the 1-point multi-unit structure is a cross grid unit rotated at a certain angle.

[0037] like Figure 9 ~ Figure 10 As shown, the 1-point multi-unit structure is a butterfly-shaped grid structure.

[0038] like Figure 11 ~ Figure 12 As shown, the 1-point multi-unit struct...

Abstract

The invention discloses a millimeter-wave grid-cell type flat array antenna, and the antenna comprises an array which is formed by a plurality of grid-type antenna units, wherein each grid-type antenna unit is a one-to-many unit structure. A waveguide opening loudspeaker is employed as a basic radiation unit of the antenna, and the interior of the waveguide opening loudspeaker is provided with a cross grid structure for segmenting the radiation port surface of one loudspeaker unit, thereby achieving the one-to-many loudspeaker units. A rear-end feed structure is enabled to be simpler while theelectric field of an antenna port surface is enabled to be more uniform and the good radiation performance of the antenna is guaranteed. A condition that the rear side of each opening loudspeaker unit needs to be connected with one feed port is changed into a condition that the rear side of four or a plurality of opening loudspeaker units is connected with one feed port. The antenna solves the problems in the prior art that a communication antenna large-scale array feed network is complex in design, is insufficient in wiring space, is difficult in processing, is narrow in band, and is low inefficiency.

Description

technical field [0001] The invention belongs to the technical fields of mobile communication and microwave transmission, and in particular relates to a millimeter wave grid unit type flat panel array antenna. Background technique [0002] With the development of wireless communication technology, people have higher and higher requirements for wireless communication equipment. In order to meet the increasingly stringent requirements of wireless communication methods for antenna modules, antennas with small size, wide frequency band, high efficiency, large capacity, easy installation, and multi-function have become a very important direction in the field of antenna research today. [0003] At present, microstrip antenna is the most widely used in radar, satellite communication, mobile wireless communication, and various communication equipment, because of its low cost, small size, light weight, low profile, and easy integration with active devices and microwave circuits. feat...
