With the rapid development of 5G technology, people have put forward many new requirements for low-dielectric materials. The newest version of 5G communication technology requires frequency ranges become higher. This means that the wavelength of waves used in the 5G communication technology become shorter. The shorter the wavelength of the electromagnetic wave is, the poorer the diffraction ability it has, and the stronger the attenuation that occurs during its propagation. The existing materials are far from meeting the new requirements of 5G technology. Therefore, the research of new low-dielectric materials has become a hot spot. This article summarizes the related researches on some new types of poly aryl ether materials with low dielectric constant and low dielectric loss to provide experience for follow-up work.
