▎ 摘　　要

NOVELTY - Terahertz narrow beam Fabry-Perot resonant antenna based on metal-graphene hybrid structure comprises fixing clamp 1 connected with ridge feed source horn. A Fabry-Perot resonant structure 2 is fixedly fixed above ridge feed supply source horn to form Fabrys resonant cavity that is fixed with metal upper surface of ridge supply horn 3. An electromagnetic wave radiated by horn feed supply horn is oscillated in Fabrys resonance structure to form required narrow beam electromagnetic radiation in main direction after regulated and controlled. The fixing clamp is provided with first fixing clamp and second fixing clamp that are connected with each other. The first fixing clip is connected with second fixing clip. USE - Terahertz narrow beam Fabry-Perot resonant antenna based on metal-graphene hybrid structure used in microwave communication field. ADVANTAGE - The terahertz narrow beam Fabry-Perot resonant antenna based on metal-graphene hybrid structure provides excellent performance, introduces design freedom of design, and is easy to design and control the beam width. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for realizing Fabry-Perot resonance structure by metal-graphene hybrid structure process, which involves: a. spin-coating photoresist on substrate that withstand high temperature process of 1000degreesC and drying to obtain complete uniform photoresist layer; b. placing mask on substrate covered with complete and uniform photoresist layer, and performing exposure, development and etching operations to form patterned photoresist layer; c. using electron beam evaporation process to evaporate uniform layer of nickel or copper on substrate; d. placing substrate into photoresist solvent, and removing patterned photoresist to obtain patterned metal film; e. placing substrate into tubular reactor, and using chemical vapor deposition method to grow patterned graphene on the patterned metal film, and finally obtaining graphene-loaded patch structure.
