Abstract

The invention provides a composite material for a 5G antenna, comprising an LCP film layer and a copper foil layer, wherein the LCP film layer uses 2,6-naphthalenedicarboxylic acid and bis(4-phenol group)-1,2-acetylene as functional monomers body with extremely low dielectric constant, dielectric loss and thermal expansion coefficient. At the same time, with 3,4-dicyanophenol, the cyano group in its structure can improve the adhesion performance of LCP material and copper foil, and improve the stability of use, but excessive amount will affect the dielectric properties due to polarity. At the same time, the LCP polymer of the present invention also includes p-hydroxybenzoic acid, which can reduce the composition within a certain range and improve the acceptability of the material.

Description

technical field [0001] The invention relates to the field of composite materials for a new generation of communication technologies, in particular to a composite material for 5G antennas. Background technique [0002] LCP is an important material widely used in 5G flexible circuit boards. It has excellent properties such as high heat resistance, low water absorption, low dielectric loss and high dimensional stability, and is an ideal material for millimeter-wave circuits. With the advent of the 5G era, the widely used polyimide antenna materials in the traditional 4G era have been unable to meet the demand. Polyimide has a large loss at the 2.4GHz frequency and cannot be used for frequencies above 10GHz. With its low dielectric constant and low dielectric loss, LCP has gradually replaced polyimide film and has become one of the most important coating materials for flexible circuit boards. The LCP and the soft copper foil substrate are pressed together to form a copper clad ...
