Although liquid crystal polymers are applied to the field of communication connectors and have a plurality of advantages, the fact that the conventional grade liquid crystal polymers cannot meet the requirements of future high-frequency communication is proved to be mainly reflected in that the dielectric properties of the conventional grade liquid crystal polymers cannot enable high-frequency signals to reach the optimal transmission state, and the liquid crystal polymers with lower dielectric constants and lower dielectric losses at high frequency are needed to realize the purpose.
