Document Type and Number:
WIPO Patent Application WO/2023/171115
Kind Code:
A1
Abstract:
An antenna device (120) comprises an element body (130), a flat radiation element (121) that is provided to the element body (130), a flat ground electrode (GND) that is provided so as to be substantially parallel to the radiation element (121), and high dielectric layers (151, 152) that are provided to side surfaces (131, 132) of the element body (130) and have a higher dielectric constant than the element body (130). At least a portion of the high dielectric layers (151, 152) is positioned between the radiation element (121) and the ground electrode (GND) as seen from the X-axis direction, which is the normal direction to the side surfaces (131, 132), and outside the ground electrode (GNS) as seen from the Z-axis direction, which is the normal direction to a top surface (130a).
