Document Type and Number:
WIPO Patent Application WO/2021/181872
Kind Code:
A1
Abstract:
An antenna device (10B) comprises at least one antenna element (1a to 1c), and a dielectric lens (2B) which is made from a dielectric material having a predetermined dielectric constant and which includes a lens body (24) having a first surface (22) and a second surface (25) opposing each other. The lens body (24) is formed so that an incident wave to the antenna element (1a to 1c) or an incident wave from the antenna element (1a to 1c) is refracted at gradually increasing angles with increasing distance from an axis (A) passing the center of the first surface (22) and the second surface (25).
