Embodiment Construction

[0028] The method of the present invention will be described in further detail below with reference to the accompanying drawings and examples.

[0029] like Figures 1 to 5 As shown in the figure, a manufacturing method of a feed source with an annular inner groove structure mainly includes the following steps:

[0030] Step 1: Analyze and decompose the annular inner groove structure. This type of structure is an axisymmetric structure, including left and right flanges and a middle cavity, and the cavity has an annular inner groove structure. On any section along the axis, the groove bottom positions of all inner grooves belong to the same busbar. By separating along the busbar, the structure can be decomposed into an outer sleeve 1 and several slices. The slices are called annular fins. The center of the annular fins is added with material to obtain the shape of the transit base, and the workpiece is processed with the shape of the transit base. The outer wall of the workpi...

Abstract

The invention relates to a manufacturing method of an annular inner groove structure feed source, which adopts separate preparation and hot fitting to solve the problems of high manufacturing cost and poor precision of the annular inner groove. The invention has novel ideas and mature technology , is easy to implement, has high precision and low cost, and effectively realizes the manufacture of a circular inner groove structure feed source, which is an important improvement over the prior art.

Description

technical field [0001] The present invention relates to the technical field of communication antennas, and in particular, to a manufacturing method of a feed source with an annular inner groove structure. Background technique [0002] With the rapid development of modern society's demand for satellite communication and the rapid development of navigation and measurement technology, communication antennas have also made great progress. A reflector antenna is a common form of communication antenna. The reflector antenna is mainly composed of a feed source and a reflector. [0003] The feed is the core component of the reflector antenna and determines the overall performance of the antenna. In order to make the reflector antenna have higher performance, it is necessary to use a higher efficiency feed. The corrugated feed, also known as the corrugated horn, is mainly composed of a mode conversion section and a horn section. In large and medium-caliber reflector antennas, the...
