Materials used in the field of high frequencies are preferably those having a small dielectric constant and a low dielectric loss tangent, particularly a low dielectric loss tangent, in order to reduce transmission loss and increase the transmission speed.
If these are large, a part of the energy given as a high frequency causes intramolecular friction inside the substance and is lost as heat. Specifically, polytetrafluoroethylene, polymethylpentene, or the like is used as a high frequency material. Fluorine-based resins such as polytetrafluoroethylene have excellent electrical characteristics, but have a problem of being molded by cutting. Other high-frequency materials, such as polyethylene and propylene, can be easily molded by injection molding and have some excellent electrical characteristics in the high-frequency range, but due to their crystallinity, the temperature dependence of their dielectric properties is large and In some cases, the electrical characteristics were insufficient.

In general, the larger the cross-sectional area of the insulator and the higher the frequency of the insulator, the larger the reflected wave with respect to the input wave to the connection site, and the larger the transmission loss. Therefore, the coaxial cable connector, especially for high frequencies, preferably has a small diameter, but if it is too small, the mechanical strength is poor and it is difficult to use because it is difficult to hold. In addition, for insulators of the same size and shape except for voids, in general, the higher the ratio of voids to the volume including voids of the insulator, the smaller the voltage standing wave ratio at high frequencies, and the higher the frequency band. But you can use it. However, if the voids are opened too much, the strength of the insulator is lowered and the insulator is easily damaged when connecting a cable. Therefore, it is necessary to provide a sufficient thickness between the voids, and it is necessary to determine the shape and arrangement of the voids so that the strength can be easily maintained.
