Title:
WAVEGUIDE CORNER AND RADIO DEVICE
Document Type and Number:
WIPO Patent Application WO/2005/099026
Kind Code:
A1
Abstract:
A first rectangular waveguide (2) is defined by H plane pipe walls (2A, 2B) and E plane pipe walls (2C, 2D). On the other hand, a second rectangular waveguide (4) is defined by H plane pipe walls (4A, 4B) and E plane pipe walls (4C, 4D). End face of the second rectangular waveguide (4) is opened to the H plane pipe walls (2A) of the first rectangular waveguide (2), and the H plane pipe walls (4A, 4B) of the second rectangular waveguide (4) are arranged along the axis of the first rectangular waveguide (2). Consequently, the planes of polarization of electromagnetic waves propagating through the first and second rectangular waveguides (2, 4) can be made to intersect perpendicularly, and a waveguide corner (1) having a mode converting action can be formed.
