Multi-band broadband tapered slot-line antenna and orthorhombic dual-polarization broadband tapered slot-line antenna

Abstract

The invention provides a multi-band broadband tapered slot-line antenna. The multi-band broadband tapered slot-line antenna is used for solving the technical problems that the requirements for the high gain and the broadband of an antenna in antenna applications of remote sensing, detection, communication, radar, a testing and simulating system and the like can not be met. According to the multi-band broadband tapered slot-line antenna, a high-band center antenna part of a slot line structure and a low-band periphery antenna part of a dual-slot-line radiation structure form a whole, and therefore the band width of the antenna is increased. The invention further provides an orthorhombic dual-polarization broadband tapered slot-line antenna. The two multi-band broadband tapered slot-line antennas are subjected to orthogonal collocation with the method that grooves are formed in the axes of the dual-slot-line radiation structures, limitation caused by the thickness of a dielectric substrate when a single-slot-line transmission section slot-line antenna is subjected to dual-polarization design is avoided, the influence of the small distance between two polarization single-slot-line transmission sections on the radiation characteristic of the antenna is avoided, and the technical problems that the requirements of the high gain, the broadband and dual polarization of the antenna in antenna applications of remote sensing, detection, communication, radar, the simulation testing system and the like can not be met are solved.

Description

technical field [0001] The invention belongs to the technical field of antennas, in particular to a multi-band broadband tapered slot line antenna and a multi-frequency band orthogonal dual-polarized broadband tapered slot line antenna. Background technique [0002] As the frequency band of the device is continuously developed, the frequency band requirements of the antenna are continuously expanded. In the prior art, antenna multi-band multiplexing often causes problems such as off-focus, interference between frequency bands, and system incompatibility, and the existing multiplexing technology often has narrow frequency bands. For example, in satellite communications, if one antenna can meet the communication problems of more frequency bands, the problems of space occupation and mutual electromagnetic coupling will be greatly simplified, and the research and development cost and difficulty of the entire system will be greatly reduced.
