ultra-high performance microwave antenna and power component

摘要

Ultra-high performance microwave antenna and power component. A power component of an ultra-high performance microwave antenna includes a sub-reflector, a dielectric head, a waveguide, and a base. the power component is rotationally symmetrical, one end of the waveguide being inserted into the base, while the other end being capable of receiving a first end of the dielectric head, the secondary reflector being provided over a second end of the dielectric head based on the shape of the second end. the waveguide portion of the dielectric head includes at least one cylinder, a side portion of the dielectric head exposed outside the waveguide includes several cylindrical surfaces of different diameter, and a tapered tapered surface is provided centrally on an end surface. From the second dielectric head end and recessed toward the first dielectric head end, a circular plane is defined at the periphery of the tapered tapered surface, and at least one perturbation construction is provided on the tapered tapered surface. The ultra-high performance microwave antenna and power components have good electrical performance, simple and compact physical structure and low manufacturing cost.
