Embodiment Construction

[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0026] Such as figure 1 As shown, the reconfigurable waveguide hybrid slot antenna cuts 16 slots 1 on each of the two waveguide wide walls and the two waveguide narrow walls. The slots in the wide wall of the waveguide are parallel to the long edges of the rectangular waveguide, and the longitudinal distance between the slots is ,in is the waveguide wavelength. There is an included angle between the cutting direction of the narrow wall of the waveguide and the vertical direction of the long edge (each included angle is different, ranging from 4-15°), and the distance between the centers of the slots is also , and cut into the wide wall of the waveguide at a certain depth. One end of the waveguide is used for feeding power, and the other end is added with a reflector 2, and the opened...

Abstract

The invention discloses a reconfigurable waveguide mixed slot antenna based on S-PIN diode. Eight to thirty-two slots are cut on the waveguide wide wall and the waveguide narrow wall of the main body rectangular waveguide of the antenna, and an S-PIN diode is mounted in each slot; and when the antenna is in operation, the S-PIN diodes of three waveguide walls having no need of generating radiation are positively biased to form a thin layer similar to metal, and all the slots on the waveguide walls are closed. The antenna radiation is generated by a slot array on the other waveguide wall, and stronger radiation can be generated in a direction required. The antenna realizes omnidirectional scanning by controlling bias voltage of the S-PIN diode. When bias voltages of all the diodes are cancelled, omnidirectional radiation can be realized. The antenna has wide horizontal plane, narrow vertical plane of scanning beam and high radiation efficiency, realizes reconfigurability of antenna radiation pattern, and can realize free switching in working modes such as omnidirectional radiation, oriented radiation, omnidirectional scanning and the like.

Description

technical field [0001] The invention relates to solid-state plasma technology and waveguide slot antenna technology, in particular to a waveguide hybrid slot antenna that utilizes solid-state plasma to realize reconfigurable pattern. Background technique [0002] The waveguide slot antenna is made by slotting on the metal waveguide, and the slotting forms generally include waveguide wide-wall longitudinal slots, waveguide wide-wall inclined slots, waveguide narrow-wall inclined slots, etc. Slot antennas have the advantages of high radiation efficiency, less energy leakage, high aperture surface utilization, compact structure, convenient installation, high strength, and strong wind resistance. They occupy an important position in the modern electronics industry and are widely used on the ground, shipboard, etc. , airborne, navigation and other fields, and the waveguide slot antenna has become the preferred form of airborne radar antenna. [0003] In recent years, in order to...
