Embodiment Construction

[0024] The technical solution of the present invention will be further described below in conjunction with the drawings and specific embodiments.

[0025] The specific technical solutions of the present invention will be further described below with reference to the accompanying drawings, so that those skilled in the art can further understand the present invention, without limiting their rights.

[0026] What needs to be explained is:

[0027] The feeder (6) and feeder (9), port (7) and port (8) appearing in the embodiment can be distinguished by different reference signs, and in the claims, the reference signs do not play a limiting role , Therefore, in order to further clarify the difference, it is written as the first feeder (6) and the second feeder (9), the left-handed circularly polarized port (7) and the right-handed circularly polarized port (8), just for distinction.

[0028] like figure 1 As shown, a wide scanning angle S-band dual circularly polarized microstrip ...

Abstract

The invention relates to a wide-aspect-angle S-band dual-circular-polarization microstrip antenna for a phased array, and the phased array. The microstrip antenna comprises a top dielectric layer, a central dielectric layer, a bottom dielectric layer, an annular structure located above the top dielectric layer, a rectangular paster and an annular structure which are located on the central dielectric layer, a gap on a ground plate, a first feed line and a second feed line which are located below the bottom dielectric layer. Two ends of the microstrip antenna are respectively connected with a left-hand circular polarization port and a right-hand circular polarization port, wherein the left-hand circular polarization is obtained through the port, and the right-hand circular polarization is obtained through the port. The microstrip antenna has the scanning range of +/-70 degrees, is wide in bandwidth, is large in beam width, is low in width-angle axial ratio, and is simple in structure. The microstrip antenna has two ports, thereby facilitating the free selection of the left-hand circular polarization mode or the right-hand circular polarization mode. The microstrip antenna can be extended to form a large-scale phased array with a random number of antennas.

Description

technical field [0001] The invention relates to a wide-scan angle S-band double-circularly polarized microstrip antenna and an array thereof for phased arrays, and is an application based on phased arrays, in particular to the technical field of phased array antennas. Background technique [0002] Dual polarization technology is a very important technology in the field of wireless communication, which can be used to realize polarization diversity and polarization multiplexing. Polarization diversity is an effective method to solve multipath fading of wireless channels, while polarization multiplexing can be used more effectively Limited spectrum resources. And the microstrip antenna has the characteristics of low profile, small size, light weight, and diverse polarization characteristics, and it is easy to integrate with the feed network and active circuit, so it has been widely used. However, the shortcoming of its narrow frequency band seriously restricts the demand for l...
