For high – frequency applications, improving the electrical performance of printed circuit boards is of great importance. New research has focused on reducing the signal loss and electromagnetic interference (EMI) in high – frequency PCBs. Through the optimization of the PCB’s dielectric material and circuit layout, the signal transmission quality has been significantly improved. This development is beneficial for applications such as 5G communication, satellite communication, and radar systems, where high – speed and reliable signal transmission is required.
