Abstract

The invention provides a reflection and transmission testing device for microwave / millimeter-wave frequency band vortex electromagnetic waves. The device includes a base, perpendicular supports, to-be-detected material fixing corners, a transmitting antenna and an antenna bracket; the perpendicular supports are fixed to the two sides of the base, the to-be-detected material fixing corners are arranged in sliding grooves in the two sides of the base and can slide in the extension directions of the sliding grooves, and a to-be-detected material placement area is arranged between the perpendicular supports and the to-be-detected material fixing corners; the antenna bracket is arranged on the base and the perpendicular supports and used for fixing the transmitting antenna. The structure is reasonable, the operation is convenient, and the reflection and transmission characteristics of the vortex electromagnetic waves are tested under cooperation with a microwave near-field measurement system. By changing the to-be-detected material fixing corners, placement inclination angle adjustment of to-be-detected materials different in thickness is achieved, and reflection and transmission testing of the vortex electromagnetic waves at different incident angles is achieved. Rotation of the antenna at different angles is achieved through interface screw holes and fixing screw holes. By adopting a frame-type non-metal material, the influence on transmission characteristic testing of the vortex electromagnetic waves is small.

Description

technical field [0001] The invention relates to the field of microwave technology, in particular to a reflection and transmission test device for vortex electromagnetic waves in the microwave / millimeter wave frequency band. Background technique [0002] With the continuous development of wireless communication technology, the electromagnetic spectrum has been fully utilized and greatly expanded. At the same time, spectrum resources have become increasingly tense and crowded, and their utilization has reached a bottleneck. As a new type of electromagnetic wave information transmission carrier, vortex electromagnetic waves have been proposed in recent years. They carry Orbital Angular Momentum (OAM) characteristics that are different from traditional plane waves. There are any number of orthogonal modes on . This new feature is expected to solve some technical bottlenecks in existing communication, radar and other fields, and can provide new technical approaches for applicati...
