The invention relates to a dielectric slab phase shifter capable of being automatically rotationally positioned. The dielectric slab phase shifter comprises a motor, a transmission mechanism, a dielectric slab, a positioning mechanism and an outer shell. The transmission mechanism comprises a transmission shaft and a gear pair which is composed of a driving pinion and a driven bull gear. The driving pinion is connected with an output shaft of the motor. A waveguide tube is fixedly sleeved with the driven bull gear and further sleeved with a positioning shaft sleeve, and the dielectric slab is fixedly arranged in the waveguide tube in the axial direction. The positioning mechanism is composed of a positioning rod, an adjusting spring and a positioning sleeve. Under the driving of the motor, the dielectric slab rotates along with the waveguide tube through meshed transmission of the driving pinion and the driven bull gear; when the dielectric slab rotates to a required phase position, the positioning rod is matched with a positioning groove to achieve positioning, meanwhile, a positioning boss triggers a positioning switch automatically, the motor is powered off, the waveguide tube is stopped at a required corner position, and rotational positioning of the dielectric slab phase shifter is achieved.
Description
technical field [0001] The patent of the invention belongs to the technical field of radar, and specifically relates to a phase shifter used for phase conversion control in a complete radar machine. Background technique [0002] At present, the dielectric plate used in the phase shifter in the radar machine can only be moved and positioned along the linear direction of the inner hole of the rectangular waveguide. see Figure 7 with Figure 8 , the medium sheet is arranged on the upper ends of more than two adjusting rods, the lower ends of the adjusting rods are connected with sliding nuts, the sliding nuts cooperate with the lead screw, and the lead screw is driven by a motor. The motor drives the lead screw, and the adjustment rod is used to realize the movement and positioning of the dielectric sheet along the linear direction. The electromagnetic wave polarization method is single, which cannot meet the higher requirements of telecommunications for phase conversion cont...
