Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to an outer coating cable material for high-frequency and high-speed communication cables and a preparation method thereof. Background technique [0002] The key to 5G communication to achieve ultra-high-speed wireless data transmission is the use of millimeter wave technology. Millimeter wave refers to the EHF frequency band, that is, electromagnetic waves with a frequency range of 30GHz to 300GHz. The wavelength of 30GHz electromagnetic waves is 10mm, and the wavelength of 300GHz electromagnetic waves is 1 mm. Millimeter wave technology can increase the frequency bandwidth and improve the signal-to-noise ratio, thereby increasing the data transmission rate. However, the higher the frequency of electromagnetic waves, the shorter the wavelength, the worse the diffraction ability, and the greater the attenuation of electromagnetic waves during propagation, whic...
