Title:
ANTENNA DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/110671
Kind Code:
A1
Abstract:
Provided is an antenna device having a ground plane, which is, when placed horizontally, capable of sending and receiving horizontally polarized electromagnetic waves. A rectangular notch 22 is provided in a ground plane 20, leaving right and left margin sections 21 that have a prescribed width. Within a plane that is substantially parallel to the ground plane 20A, a resonance-type antenna element 30 is provided at a position that overlaps the position of the notch 22. Thus, when the antenna element 30 is positioned horizontally, horizontally polarized electromagnetic waves can be generated in the horizontal direction.
