Title:
WAVEGUIDE SLOT ARRAY ANTENNA DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/145842
Kind Code:
A1
Abstract:
Portions of bent end portions (14, 15) of a slot (11) are configured so as to coincide with a waveguide inner wall (3) when viewed from a direction normal to a narrow wall surface (5) in which the slot (11), which is of a waveguide (1), is provided. Accordingly, the conductance of the slot alone is capable of being made small by adjusting the amount of joining between a leading edge portion of the slot (11) and the inner wall of the waveguide (1). Therefore, when the width of the waveguide has been restricted to a short value relative to the length of the slot, it is possible to match an impedance with a waveguide join portion even when a large number of slots is provided per waveguide.
