A Dielectric Metal Hybrid 3D Printed Hyperbolic Lens Antenna

Abstract

The invention discloses a medium-metal hybrid three-dimensional printing hyperbolic lens antenna, which comprises an antenna, a first housing, a second housing, a housing docking plug, a housing docking socket and a lens, and the antenna is fixedly installed on the In the middle part of the first housing, the first housing and the second housing are detachably connected by the housing docking plug and the housing docking socket, and the lens is fixedly arranged on the second housing. Inside the second shell. Compared with the prior art, the present invention adopts resin material instead of metal material to produce cylindrical support structure, eliminates the electromagnetic wave reflection caused by metal material, and improves the reflection coefficient of the feed source horn. The present invention designs a wave impedance matching layer with a dielectric constant gradient characteristic at the interface between the lens and the air, effectively eliminates electromagnetic wave reflection caused by mismatching, and improves the reflection coefficient of the feed source horn. The invention adopts the three-dimensional printing technology to process the antenna, which has shorter period and high flexibility compared with the traditional processing method.

Description

technical field [0001] The invention relates to a communication technology device, in particular to a dielectric metal mixed three-dimensional printing hyperbolic lens antenna. Background technique [0002] The hyperbolic lens antenna is a kind of high-gain antenna, which is widely used in long-distance directional wireless communication data link and satellite communication. The hyperbolic lens antenna is usually composed of a lens, a cylindrical support structure antenna and a feed horn. The feed horn is focused by the lens to achieve high gain. Unlike other high-gain antennas, hyperbolic lens antennas have more design freedom and are easier to achieve high gain. The lens is usually processed by casting molds. The mold is produced first, and then the mold is poured with hot-melt medium, and then polished after cooling and forming; the support structure is usually cylindrical and processed by steel plate welding; the feed speaker is usually CNC Machine tool machining.

AI Technical Summary

Problems solved by technology

Disadvantages of the existing technology: (1) The metal cylindrical support structure will reflect the electromagnetic wave emitted by the feed source horn, which will affect the reflection coefficient of the input end of the feed source and cause signal reflection, and the cylindrical metal support structure is heavy, which is not conducive to engineering applications

(2) At the interface between the lens and the air, due to the sudden change in the dielectric constant of the lens, unnecessary reflections are usually formed, which will affect the performance of the lens and cause signal reflections

(3) The antenna processing technology is complicated, the cycle is long, and the flexibility is poor
