Abstract

The invention provides a high-thermal-conductivity carbon fiber composite material antenna and a preparation method thereof, and relates to the technical field of composite material antennas. The high-thermal-conductivity carbon fiber composite material antenna comprises an antenna body, the antenna body comprises an antenna base layer, and a bonding layer is arranged on the outer surface of the antenna base layer. A protective layer is arranged at the side, away from the antenna base layer, of the bonding layer, the antenna base layer is made of graphene and carbon fiber materials, the thickness of the antenna base layer is 30-50 microns, and the thickness ratio of the antenna base layer to the bonding layer to the protective layer is 1: 0.4: 0.5. The graphene and the carbon fibers are adopted as the manufacturing materials of the antenna, so that when the composite material antenna is used, heat generated inside can be uniformly distributed, the phenomenon of thermal expansion and cold contraction of the composite material antenna can be avoided, and focusing of the composite material antenna is facilitated.

Description

technical field [0001] The invention relates to the technical field of composite material antennas, in particular to a high thermal conductivity carbon fiber composite material antenna and a preparation method. Background technique [0002] An antenna is a transformer that transforms a guided wave propagating on a transmission line into an electromagnetic wave propagating in an unbounded medium (usually free space), or vice versa. A component used in radio equipment to transmit or receive electromagnetic waves. Engineering systems such as radio communication, broadcasting, television, radar, navigation, electronic countermeasures, remote sensing, and radio astronomy, which use electromagnetic waves to transmit information, rely on antennas to work. In addition, in terms of transmitting energy with electromagnetic waves, non-signal energy radiation also requires antennas. Generally, antennas are reversible, that is, the same antenna can be used as both a transmitting antenn...
