Embodiment Construction

[0021] The WR3 standard waveguide used in the present invention can be found in figure 1 , a phase-shifting structure 21 is set in the waveguide 20, such as figure 2 shown. The phase shifting structure 21 is a rectangular plate-shaped member, including a microstrip structure with Schottky diodes arranged on a rectangular quartz dielectric substrate. The long side of the dielectric substrate is parallel to the axis of the waveguide and the bottom surface of the dielectric substrate is perpendicular to the E surface of the waveguide. The distance from the intersection line between the dielectric substrate and the E surface of the waveguide to the H surface of the waveguide is 1 / 4 of the width L of the E surface. see image 3 , 4 , image 3 , 4 is the viewing angle parallel to the waveguide section. One embodiment of the present invention is to split the waveguide at 1 / 4 of the width L of the E plane (along image 3 , 4 The dotted line cut) into two parts, and according ...

Abstract

The invention provides aterahertz phase shifter based on a WR3 standard waveguide loaded phase shifting microstructure, and relates to terahertz technology. The terahertz phase shifter comprises a WR3standard waveguide and a phase shifting structure. The phase shifting structure comprises a microstrip structure with Schottky diodes arranged on a rectangular quartz dielectric substrate.The microstrip structure comprises a first Schottky diode group, a second Schottky diode group, a third Schottky diode group and a fourth Schottky diode group which are arranged in parallel in sequence. The closed structure (WR3 standard waveguide) is utilized to improve the high loss of terahertz (THZ) wave in an open structure, and the microstructure with diodes is spliced on the surface of the quartz dielectric substrate to realize digitization of the terahertz (THZ) phase shifter so as to have good phase shifting characteristics.

Description

technical field [0001] The present invention relates to terahertz technology. Background technique [0002] Terahertz (Tera Hertz, THz) waves include electromagnetic waves with a frequency of 0.1 to 10 THz, so Tera Hertz waves have the advantages of high natural frequency and wide bandwidth, so the spatial resolution and distance resolution of Tera Hertz (THZ) radar are very good. high. Among them, the phased array radar has the advantages of flexible wave scanning, ability to track multiple targets, and good anti-interference performance. As a key component of the terahertz (THZ) phased array, the cost and performance of the phase shifter directly affect the phased array radar system. cost and performance. Therefore, it is of great practical significance to study high-performance, easy-to-implement, and low-cost THz phase shifters to improve the performance and structure of phased arrays and realize small, low-power THz phased array radars. [0003] The short-wavelength ...
