Embodiment Construction

[0029] The structural features of the present invention will now be described in detail in conjunction with the accompanying drawings.

[0030] see figure 1 , an X-band phased array waveguide antenna is a waveguide array antenna composed of slotted waveguides. The slotted waveguide is composed of a reflector 1 , an intermediate body 2 , a transition body 3 , a transformation body 4 , a coupling body 5 and a radio frequency connector 6 which are sequentially connected end to end. The back of the reflector 1 and the front of the intermediate body 2 form a first-stage cavity, the back of the intermediate body 2 and the front of the transition body 3 form a second-stage cavity, and the back of the transition body 3, the conversion body 4, and the coupling body 5 share a common Constitute the third-level cavity. Slits are respectively opened on the reflector 1, the intermediate body 2, the transition body 3 and the conversion body 4. A radio frequency connector 6 is mounted on t...

Abstract

The invention provides an X-waveband phased-array waveguide antenna. A whole waveguide array is taken as a transmission body to substitute the traditional radar antenna combined by a line source transmission body and a crack waveguide. The X-waveband phased-array waveguide antenna is an aggregation body formed by sequentially connecting a reflector, an intermediate body, a conversion body, a coupling body and a radio-frequency connector and comprises a plurality of waveguide monomers. The X-waveband phased-array waveguide antenna has the technical effects that a layered structure is adopted, the antenna is partitioned to five layers of single-layer bodies and is formed through vacuum brazing in one time, the processing is simple, time and labor are saved, and the assembly accuracy is high. The X-waveband phased-array waveguide antenna is compact and attractive in the whole appearance, has the characteristics of small volume, high precision and high gain, and is suitably used for the structural design of a phased-array system radar antenna in the ground, aviation and the like.

Description

technical field [0001] The invention belongs to the technical field of radar antennas, in particular to the field of phased array system radar, in particular to an X-band phased array waveguide antenna. Background technique [0002] Antenna is a very important device in the field of electronic equipment such as radar and communication, and has the function of transmitting and receiving signals. The existing waveguide slot array antenna is assembled and integrated by individual slot waveguides through screw fixing, etc., and then connected with the line source body to form a complete antenna array. At the same time, it has the disadvantages of large shape, complex structure, high assembly precision requirements, and low electrical performance indicators. Generally, it cannot be small in size and simple in structure. Contents of the invention [0003] The object of the present invention is to provide an X-band phased array waveguide antenna, which adopts an integrated waveg...
