Document Type and Number:
WIPO Patent Application WO/2020/213203
Kind Code:
A1
Abstract:
The invention is to suppress bend distortion of a radiation element, thereby stabilizing the radiation characteristic of the radiation element and widening an antenna band. An antenna according to the invention is provided with: a dielectric laminate having a plurality of stacked dielectric layers; a dielectric board joined to one surface of the dielectric laminate; and a radiation element pattern layer, a ground conductor layer and a conductor pattern layer that are respectively formed on both surfaces of the dielectric laminate and in any one of different places between the layers thereof. The radiation element pattern layer, the ground conductor layer and the conductor pattern layer are formed in the order of the radiation element pattern layer, the ground conductor layer and the conductor pattern layer in the direction from the dielectric board side to the opposite side. The radiation element pattern layer has one or more radiation elements. The conductor pattern layer has a feeding line for feeding the radiation elements. The dielectric laminate is flexible. The dielectric board is rigid.
