Abstract
Official abstract text for this publication.
The present invention relates to a waveguide for transmission of electromagnetic wave signals. According to one aspect of the invention, there is provided a waveguide for transmission of electromagnetic wave signals, comprising: a dielectric part comprising two or more dielectrics having different permittivity; and a conductor part surrounding at least a part of the dielectric part.
First claim
Opening claim text (preview).
What is claimed is: 1 . A waveguide for transmission of electromagnetic wave signals, comprising: a dielectric part comprising two or more dielectrics having different permittivity; and a conductor part surrounding at least a part of the dielectric part. 2 . The waveguide of claim 1 , wherein the two or more dielectrics comprise a first dielectric and a second dielectric, and the second dielectric surrounds at least a part of the first dielectric. 3 . The waveguide of claim 2 , wherein central axes of the first dielectric, the second dielectric, and the conductor part coincide with each other. 4 . The waveguide of claim 2 , further comprising: a support disposed between the first dielectric and the conductor part to maintain a space in which the second dielectric is located between the first dielectric and the conductor part. 5 . The waveguide of claim 2 , wherein the first dielectric consists of two or more partial dielectrics separated from each other, and the second dielectric surrounds at least a part of the two or more partial dielectrics. 6 . The waveguide of claim 2 , wherein one of the first dielectric and the second dielectric consists of air. 7 . The waveguide of claim 2 , wherein a signal transmitted through the waveguide is guided along a boundary between the first dielectric and the second dielectric, or along a boundary between the first dielectric or the second dielectric and the conductor part. 8 . The waveguide of claim 1 , wherein a change in a group delay, which occurs according to a frequency change in a signal transmission channel via the waveguide, does not exceed a predetermined level.
