Abstract

The invention discloses a metasurface-based heterogeneous integrated terahertz front end and a manufacturing method thereof. The metasurface-based heterogeneous integrated terahertz front end comprises a shell; a fourth cover plate of an n-shaped structure is arranged at the top of the shell; a cavity is formed by the fourth cover plate and the shell; a metasurface and a reflecting face are arranged in the cavity; the metasurface is made of an insulating medium material with electromagnetic parameters; a metal film coats the insulating medium material; a terahertz circuit, a power source paneland a control panel are arranged in the shell, wherein the power source panel is connected with the terahertz circuit, the control panel and the metasurface, and the control panel is connected with the terahertz circuit and the metasurface; a feed source is further arranged in the shell; and electromagnetic waves generated by the terahertz circuit can be radiated to the reflecting face through the feed source. Beam scanning is realized without adding an external mechanical device so that the size, weight and cost advantages of the metasurface-based heterogeneous integrated terahertz front endcan be further expanded, and the requirement of engineering application of terahertz front-end products can be met.

Description

technical field [0001] The invention relates to the technical field of terahertz front-ends, in particular to a metasurface-based heterogeneous integrated terahertz front-end and a manufacturing method thereof. Background technique [0002] The terahertz front-end is generally composed of antennas, transceiver components, housings and accessories. The accessories mainly include cables, fasteners, glue, gaskets, etc. The traditional terahertz front-end antenna and transceiver components are designed separately, so they are bulky and heavy. Traditional terahertz antennas generally use horn antennas, reflector antennas, or horn-reflector combination antennas, which do not have beam scanning capabilities themselves. To use the traditional terahertz front-end to realize the beam scanning function necessary for communication equipment and radar equipment, it is necessary to add mechanical transmission and mechanical control devices, which further deteriorate its size, weight and ...
