Title:
ANTENNA DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/230039
Kind Code:
A1
Abstract:
[Problem] To make it possible to obtain a more preferable radiation pattern even when arraying a plurality of antenna elements. [Solution] This antenna device is provided with: a dielectric substrate; a plurality of antenna elements arranged along a first direction, each of the antenna elements transmitting or receiving a first wireless signal and a second wireless signal which have different polarization directions from each other; and a ground plate in which an elongated slot is provided extending in a second direction in a corresponding region between first and second antenna elements neighboring each other, wherein, when λ0 is the wavelength of a wireless signal, εr1 is the relative permittivity of the dielectric substrate, and εr2 is the relative permittivity of a dielectric located on the opposite side of the dielectric substrate with respect to the ground plate, the length L of the slot in the second direction satisfies the conditional equation shown below.
