  • Patent number: 8026774
    Abstract: 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.

  • Patent number: 7952449
    Abstract: A coaxial connector includes a first inner conductor and a second inner conductor. A capacitor connects between the first inner conductor and the second inner conductor. An outer conductor extends along and surrounds the first and second inner conductors and the capacitor. A first dielectric material is filled in a gap between the outer conductor and the first and second inner conductors. A support member supports the first and second inner conductors with respect to the outer conductor. A second dielectric material for impedance matching is provided between the capacitor and the outer conductor.
