Document Type and Number:
WIPO Patent Application WO/2021/033447
Kind Code:
A1
Abstract:
In the present invention, a first region and second region, which are planar, are defined on a support member. The first region and the second region are either located in the same plane or are parallel to each other. At least one first radiation element that sends and/or receives radio waves of a first frequency is disposed in the first region. At least one second radiation element that sends and/or receives radio waves of a second frequency higher than the first frequency is disposed in the second region. In a view of the second region from the direction of a line normal to the second region, an angle of 45°-90° is formed by a separation direction, which is the direction along a straight line connecting the geometrical center position of the entirety of the first radiation element to the geometrical center position of the entirety of the second radiation element, and a polarization direction of the second radiation element.
