Problems solved by technology

The metallization of composite material antennas usually adopts the method of coating conductive glue to make the metallization have a radiation function. Due to the limitations of the coating process, this method will lead to uneven coating, resulting in inconsistent surface resistance and poor matching. Variation of VSWR

Embodiment 1

[0031] First of all, apply the release agent to the tooling, and the surface temperature of the tooling should not be lower than 15°C when painting. If it is the first time to apply the release agent, apply three continuous and complete thin layers of release agent on the surface of the tooling, each layer is perpendicular to the coating direction of the previous layer, each layer needs to be dried for at least 15 minutes, and the final coating After the coating is completed, it should be dried for at least 30 minutes, and it should be dried at 120±5°C for at least 30 minutes before starting to lay the layer. If the release agent is applied again, apply one or more layers of release agent. If multiple layers are applied, each layer needs to be dried for at least 15 minutes. Let dry for at least 30 minutes. If the tooling has been sanded, apply the release agent as the first application.

Abstract

The present invention provides a method for improving of a standing-wave ratio of a composite material antenna. The method comprises: brushing release agent on a tool; unfreezing fibre cloth prepreg and an adhesive film; cutting a metal mesh and the fibre cloth prepreg according to the shape of the tool; performing laying of the cutting metal mesh and the fibre cloth prepreg at a laying position of the tool; uniformly brushing electrocondution slurry on the metal mesh after laying, and cooling the metal mesh to a room temperature after solidification and performing polishing; and installing afeed, a matching circuit and components to obtain a composite material antenna. The method for improving of a standing-wave ratio of a composite material antenna greatly improve uniformity of brushingof electrocondution slurry to allow surface resistance of the antenna to be more uniform and enhance the matching so as to improve the standing-wave ratio of the composite material antenna.

Description

technical field [0001] The present invention relates to antennas, and more particularly, to a method of improving the standing wave ratio of composite material antennas. Background technique [0002] An antenna is a transformer that converts the guided wave propagating on the transmission line into an electromagnetic wave propagating in an unbounded medium (usually free space), or vice versa, used in radio equipment to transmit or receive electromagnetic waves part. 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 antenna and a receiving antenna. The basic characte...
