Abstract

The invention relates to an antenna fabrication method and an antenna with the same. The method comprises the following steps of fabricating a graphene oxide thin film on a surface of an insulation substrate; and performing laser direct-writing on one side, far away from the insulation substrate, of the graphene thin film so as to reduce to obtain a target antenna. The fabrication method belongs to a material increasing mode to fabricate the antenna and is suitable for antenna fabrication on a plane and a curve surface, antennas with a planar structure or a curve-surface structure can be fabricated, and a high-flexible antenna also can be fabricated. The antenna with same preset pattern can be fabricated in one step by laser direct writing; and compared with a process of growing graphene on the metal substrate under a vacuum environment, transferring the graphene to a transparent substrate from the metal substrate and obtaining a graphene target pattern by laser cutting material reduction mode, the method is simple and is low in cost, and resources are saved.

Description

technical field [0001] The invention relates to the field of antennas, in particular to an antenna preparation method and an antenna having the same. Background technique [0002] As a radiation and receiving device for radio waves, the antenna is an indispensable part of electronic communication equipment. As modern communication equipment continues to develop in the direction of miniaturization, high integration, and multi-function. The processing technology of the existing graphene antenna is complex and time-consuming. The commonly used preparation methods include screen printing and mask etching. The mask layer for setting the antenna pattern is prepared in advance, and the graphene slurry is scraped The pattern of the mask layer is transferred to the target substrate by means of material or ion etching of the graphene film, and then the graphene antenna is obtained through subsequent processing (such as baking, etc.). These template-based preparation methods are not ...
