Title:
MULTILAYER BOARD
Document Type and Number:
WIPO Patent Application WO/2023/210198
Kind Code:
A1
Abstract:
This second radiation conductor layer is provided in a laminate so as to be in contact with a second insulator layer and is located in the positive direction of a Z-axis from the first radiation conductor layer. The second radiation conductor layer overlaps with a first radiation conductor layer when viewed in the Z-axis direction. The frequency of the electromagnetic wave radiated or received by the second radiation conductor layer is higher than the frequency of the electromagnetic wave radiated or received by the first radiation conductor layer, or the area of the second radiation conductor layer is smaller than the area of the first radiation conductor layer. A first planar ground conductor layer is located in the negative direction of the Z-axis from the first radiation conductor layer, and overlaps with the first radiation conductor layer and the second radiation conductor layer when viewed in the Z-axis direction.
