Radio frequency signal transmission method with coaxial connection having a dielectric material for impedance matching

摘要

A radio frequency signal transmission method for transmitting a radio frequency signal through an inner conductor serving as a signal line, the radio frequency signal transmission method including: causing the radio frequency signal to be input to and propagate through the inner conductor, an impedance between the inner conductor and an outer conductor serving as a grounding line being adjusted to a predetermined impedance; and causing a component of the radio frequency signal to propagate through a capacitor provided in a middle of the inner conductor, an impedance at a portion of the capacitor installed being adjusted to match the predetermined impedance by a dielectric material provided around the capacitor.
