Title:
HIGH-FREQUENCY WAVEGUIDE AND PHASE SHIFTER USING SAME, RADIATOR, ELECTRONIC DEVICE WHICH USES THIS PHASE SHIFTER AND RADIATOR, ANTENNA DEVICE, AND ELECTRONIC DEVICE EQUIPPED WITH SAME
Document Type and Number:
WIPO Patent Application WO/2010/050122
Kind Code:
A1
Abstract:
This high-frequency waveguide is formed by first/second conductors (22, 23) which are arranged facing each other with an interval of less than λ0/2 when the free space wavelength of the operating frequency of the high-frequency signal is λ0. In a waveguide-forming part between these first/second conductors (22, 23), a ridge (25) which protrudes from one toward the other of the first/second conductors (22, 23) and which is formed by extending along the waveguide-forming part is provided. Multiple columnar protrusions (24) with a height of λ0/4 are arranged with an interval of less than λ0/2 on at least one of the first/second conductors (22, 23) outside of the aforementioned waveguide-forming part and lateral to the ridge (25).
