ANTENNA DEVICE
Document Type and Number:
Japanese Patent JP2018157261
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an antenna device capable of achieving a high radiation efficiency even using a dielectric substrate.SOLUTION: The antenna device includes: a dielectric substrate; a conductor plate formed at a first surface of the dielectric substrate and having a slot in which the first surface exposes; a feedline which is formed at a second surface on the opposite side to the first surface of the dielectric substrate and substantially parallel to the first surface and which is branched on at least two stubs passing through the inside of an orthogonal projection on the second surface of the slot; and at least one electron hole penetrating through the first surface and the second surface of the dielectric substrate to form no overlapping onto the stub inside the slot.SELECTED DRAWING: Figure 1
