Single pulse antenna with double V shaped linear gradually changing slot

Abstract

A double V-shaped linear tapered slot monopulse antenna can be applicable to the systems of tracking, detection, communication, measurement, astronomical observation, etc. The antenna comprises an upper layer metal copper bonded surface (1), a lower layer metal copper bonded surface (2), a dielectric substrate (3), a metallized through hole (4), a substrate integrated waveguide 90-degree directional coupler (51), a 90-degree phase shifter (52), a substrate integrated waveguide H-plane wave generator (6), an input port (71), an output port (72), a double V-shaped linear tapered slot antenna (8), an upper surface triangular metallic cladding (81) and a lower surface triangular slot (82); a multimode substrate integrated waveguide is adopted for feeding to form a monopulse antenna. The double V-shaped linear tapered slot monopulse antenna works at the millimeter wave frequency band, can be directly applied to the integrated circuit design, and is characterized by low consumption, small volume, low cost and being easy for mass production, etc.

Description

technical field [0001] The double V-shaped linear tapered slot monopulse antenna of the present invention can be applied to systems such as tracking, detection, communication, measurement, and astronomical observation. Background technique [0002] The monopulse antenna is a precision tracking antenna that appeared after the Second World War and developed rapidly in the 1950s and 1960s. With the development of missiles, rockets, artificial satellites and aerospace technology, the original sequential beam method and cone scanning method cannot meet the new requirements in terms of tracking accuracy and speed of obtaining target angle information. In principle, the single-pulse system (also known as the simultaneous beam method) only needs one echo pulse to obtain the distance and all angular coordinate information of the target, which greatly speeds up the speed of extracting the target angle information, and its tracking accuracy, anti-corrosion The jamming ability and vari...

AI Technical Summary

Problems solved by technology

For traditional planar transmission lines, such as microstrip lines, coplanar waveguides, etc., their structure is simple, easy to manufacture, and low in cost, but the fatal disadvantage is that they will cause a lot of loss when working in the millimeter wave band

The feed source made of metal waveguide has excellent performance, but the structure is complex, difficult to manufacture, and high in cost.
