Novel waveguide standing wave matcher

Номер: CN103296365A
Принадлежит:

A novel waveguide standing wave matcher comprises a straight waveguide and eight screws. Screw holes matched with the screws are formed in a wide side of the straight waveguide. The novel waveguide standing wave matcher is characterized in that adjacent screws are equidistantly arranged at distances of 1/16, 3/16 or 5/16 of the wavelength of a central frequency waveguide. The eight screws are uniformly distributed in an impedance circle diagram, heights of the screws are selectively adjusted according to a standing wave frequency amplitude changing curve, matching of a feeder system can be quickly completed through proper screw combinations, and dead-corner-free matching in a low-power state is realized. The novel waveguide standing wave matcher is stable and reliable in performance and low in cost.

Novel conical scanning antenna

Номер: CN103259090A
Принадлежит:

A novel conical scanning antenna comprises a parabolic face, a feed source and a sub face, and is characterized in that a motor and a crank shaft are included, the motor comprises a motor shaft, a first end of the crank shaft is connected with the motor shaft, an axis of the motor shaft coincides with an axis of the parabolic face, an installation seat is arranged on the top point of a concave face of the sub face, second end of the crank shaft stretches along the axis of the sub face and is arranged on the installation seat, and the sub face achieves offset-focus rotary conical scanning driven by the motor. Based on a classic clamping type antenna, communication in motion through off-focus rotation of the sub face is achieved, and the novel conical scanning antenna is simple in structure, easy to machine and debug, and low in product cost.
