Title:
ANTENNA ELEMENT
Document Type and Number:
WIPO Patent Application WO/2022/064864
Kind Code:
A1
Abstract:
In the present invention, a first planar ground conductor layer is connected to a ground potential and is provided to an insulating substrate. A first emitting conductor layer emits and/or receives a first high-frequency signal, the first emitting conductor layer being provided to the insulating substrate and being positioned on the first planar ground conductor layer. A lower main surface of the first emitting conductor layer overlaps an upper main surface of the first planar ground conductor layer as seen from the vertical direction. A first ground conductor is connected to the ground potential and is provided to the insulating substrate. The upper end of the first ground conductor is positioned higher than the first emitting conductor layer. The first ground conductor layer is set apart from the first emitting conductor layer as seen from the vertical direction. Aside from a conductor by which the first high-frequency signal is transmitted or a conductor connected to the ground potential, no conductor is provided between the first ground conductor and the first emitting conductor layer as seen from the vertical direction.
