Title:
SLOT ANTENNA DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/190343
Kind Code:
A1
Abstract:
A slot antenna device includes a first electrically conductive member having first and second electrically conductive surfaces; a second electrically conductive member having a third electrically conductive surface that opposes the second electrically conductive surface; a waveguide member on the second electrically conductive surface; and an artificial magnetic conductor extending on both sides of the waveguide member. The first electrically conductive member has a slot. The waveguide member has a waveguide face that opposes the third electrically conductive surface. The third electrically conductive surface, the waveguide face, and the artificial magnetic conductor define a waveguide. The waveguide member includes a first ridge and a second ridge. As viewed from a direction perpendicular to the waveguide face, the slot is located between the one end of the first ridge and the one end of the second ridge. At least one of a spacing between the waveguide face and the third electrically conductive surface and a width of the waveguide face is varied along a direction that the waveguide member extends.
