Title:
WAVEGUIDE SLOT ANTENNA
Document Type and Number:
WIPO Patent Application WO/2020/110610
Kind Code:
A1
Abstract:
Provided is a waveguide slot antenna suited for miniaturization while maintaining good characteristics on the basis of the structure and arrangement of a power feeding unit. This waveguide slot antenna is configured by providing a power feeding unit (15) to a waveguide which is configured from a dielectric substrate (10), a first conductor layer (11) formed on a lower surface of the dielectric substrate, a second conductor layer (12) which is formed on an upper surface of the dielectric substrate and is provided with one or more slots 14, and a pair of side wall portions (W1, W2) electrically connecting between the first and second conductor layers and extending in a first direction (X), wherein the power feeding unit (15) is formed to pass between the lower surface of the dielectric substrate and the upper surface of the dielectric substrate. The waveguide slot antenna has a structure wherein the one or more slots include a first slot (14a) having a slot length (L) along the first direction, the power feeding unit is arranged at a position overlapping the first slot as seen in plan view from a second direction (Z), and the power feeding unit does not extend beyond the range of the slot length along the first direction.
