Abstract

The invention discloses a feed source with a low standing-wave ratio and high cross polarization. The feed source includes a radiation mouth, a cavity and a 90-degree converter, wherein one end of the cavity is connected with the radiation mouth, and the other end of the cavity is connected with the 90-degree converter; isolating needles, a rectangular-circular converter and a groove are arranged in the cavity; the 90-degree converter is connected with the rectangular-circular converter in the cavity; a first port is formed in the cavity, and a second port is formed in the 90-degree converter. The feed source provided by the invention adopts a separated structure, and is manufactured by a numerical control device, so that the product consistency is good, and electrical performance indicators are ensured; as the assembly process is simple, the feed source is quite suitable for batch production.

Description

technical field [0001] The invention belongs to the technical field of microwave antennas, in particular to a feed source with low standing wave ratio and high cross polarization. Background technique [0002] The current dual-polarization feed head is mostly a one-piece structure, which is completed by stretching, processing, and welding. The manufacturing process is complex, welding is easy to cause deformation, product consistency is poor, electrical performance indicators are difficult to guarantee, and it is difficult to achieve low standing wave ratio and high cross poles The electrical performance index requirements of the chemical feed are not conducive to mass production. Contents of the invention [0003] The purpose of the present invention is to provide a low VSWR high cross-polarized feed head, which adopts a split structure and is compact in structure through simulation design. The whole feed head is processed by numerical control equipment, the...
