Abstract

The invention relates to a multimode substrate integrated waveguide monopulse antenna which can be directly applied to microwave and millimeter wave tracking systems, detection systems, communicationsystems, measurement systems, astronomy observing systems and the like and can serve as a feed source of a parabolic reflector antenna and a cassegrain antenna. An upper layer metal copper-clad surface (1) and a lower layer metal copper-clad surface (2) of the antenna are respectively arranged on the front side and the reverse side of a medium substrate (3); a plated-though-hole (4) is connected with the upper layer metal copper-clad surface (1) and the lower layer metal copper-clad surface (2) after passing through the medium substrate (3) to form a substrate integrated waveguide 3dB directional coupler (5), a substrate integrated waveguide 90-degree phase shifter (6), a substrate integrated waveguide wave mode device (7) and a master wave guide (8) which are arranged in sequence, i.e. the output end of the former component is connected with the input end of the latter component; the substrate integrated waveguide 3dB directional coupler (5) is respectively connected with a first input port (101) and a second input port (102), and the output end of the main wave guide (8) is connected with the input end of a horn antenna (9).

Description

Technical field [0001] Multimode substrate integrated waveguide monopulse antenna can be directly applied to microwave and millimeter wave tracking, detection, communication, measurement, astronomical observation and other systems, and can also be used as a feed source for parabolic reflector antennas and Cassegrain antennas to achieve high gain, Narrow beam monopulse antenna. Background technique [0002] Monopulse antenna is a precision tracking antenna that appeared after World War II 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 conical scanning system cannot meet the new requirements in terms of tracking accuracy and speed of obtaining target angle information. The single pulse system (also known as simultaneous beam method) in principle only needs one echo pulse to obtain the distance and all angular coordinate information of the target. This ...
