Title:
ANTENNA, ARRAY ANTENNA, AND WIRELESS COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/221054
Kind Code:
A1
Abstract:
Provided is an antenna element resistant to loss of electrical performance even when water droplets become attached thereto. The antenna element of the present invention is provided with a conductor portion and is characterized in that, at a location on a surface of the conductor portion in which the field intensity during operation is stronger than in other locations, a first dielectric having a thickness of not less than 0.005λ is formed, wherein λ is the vacuum wavelength of the electromagnetic waves of an antenna operation frequency.
