Problems solved by technology
The antenna is a multi-layer microstrip patch antenna. Usually, the working bandwidth limit is 1 multiplier. It is characterized by simple processing and high precision, but its dielectric loss is large and the radiation efficiency is low. Process design, high processing cost
[0007] The above broadband antenna forms have their own advantages and disadvantages. Although some indicators have better characteristics, other indicators have poorer characteristics, which cannot meet the requirements of broadband and low cost at the same time.

The invention discloses a broadband dual-linear polarization array antenna and belongs to the technical field of dual-polarization broadband oscillator antennas. The antenna comprises a reflecting plate, two oscillator radiation units and two coaxial plugging connectors; each oscillator radiation unit comprises four cuboid supporting columns; the top end of each cuboid supporting column is provided with an oscillator; two feeder line structures in an orthogonal polarization relation are arranged in each oscillator radiation unit; each feeder line structure is a metal strip sheet bent into foursections, wherein the fourth section of the strip sheet is attached to the reflecting plate, the first section of the strip sheet is located between two adjacent cuboid supporting columns with a gapformed between the lower end of the first section of the strip sheet and the reflecting plate, the third section of the strip sheet is located between the other two cuboid supporting columns, and thetwo oscillators on two sides of the third section of the strip sheet are short-circuited; an air strip line network is arranged between the two feeder line structures in the same polarization direction in the two oscillator radiation units; and the air strip line network is connected with the coaxial plugging connectors. The antenna has the advantages of simple and compact structure, high radiation efficiency and excellent performance.
Description
technical field [0001] The invention relates to the technical field of broadband microwave communication, base station communication and dual-polarized broadband dipole antenna, in particular to a broadband dual-linear polarized array antenna. Background technique [0002] At present, in the field of wireless communication and mobile communication, the frequency band of communication is getting wider and wider, and the requirements for radio frequency terminals are getting higher and higher, which requires the working bandwidth of the antenna to be gradually widened. At this stage, antennas that can meet broadband radiation mainly have the following forms: [0003] 1. Plate line antenna. This type of antenna feeds the half-wave oscillator through the plate-line transmission line structure. The plate line is a pure metal structure and is filled with air medium. Feed through the plate-line can obtain low feeder loss and reliable structural support. With the help of coaxial ...
