Abstract

The invention discloses a high-power radial line sealed window which mainly solves the problem in the prior art that a mature sealed window aiming at a radial line is lacked and technical development requirements cannot be met. The high-power radial line sealed window comprises a radial line upper plate, a radial line lower plate, a radial line installed between the radial line upper plate and the radial line lower plate, a coaxial waveguide vertically connected with the radial line lower plate, a conversion cone with the upper end fixed on the radial line upper plate and a ceramic ring located between the radial line upper plate and the radial line lower plate, on the outer side of the conversion cone and coaxial with the coaxial waveguide. An inner conductor is arranged in the coaxial waveguide at the center position, and the inner conductor is connected with the lower end of the conversion cone. By means of the scheme, the window achieves the aims of being small in reflection, high in transmission efficiency, high in power volume and suitable for the radial line, and has high practical value and popularization value.

Description

technical field [0001] The invention relates to a sealing window in the technical field of high-power microwaves, in particular to a high-power radial line sealing window. Background technique [0002] With the development of high-power microwave technology, people put forward higher and higher requirements for the use of high-power microwave systems. Because high-power radial line array antennas are easy to achieve high gain, high efficiency, high power, and circularly polarized radiation, they have been extensively studied in high-power applications. The high-power radial line array antenna studied before has no sealing window. In order to achieve high power capacity, it is necessary to vacuumize the interior of the array antenna and ensure that the vacuum degree meets the requirements to prevent air breakdown from affecting performance. However, due to the large internal space of the array antenna and the many sealing links and positions, the overall vacuuming is difficu...
