Document Type and Number:
WIPO Patent Application WO/2018/212306
Kind Code:
A1
Abstract:
In the present invention, an antenna device equipped with multiple antennae is configured such that for one of the antennae the average gain in one direction is higher than the average gain in the other direction. The antenna device is provided with a first antenna for vertically-polarized waves having a dipole antenna 31, and a second antenna having a capacitive load component 60 serving as a planar conductor component and a helical component 70, wherein the capacitive load component 60 of the second antenna is disposed adjacent to the first antenna. The capacitive load component 60 functions as a reflector, whereby the gain of the first antenna is improved in the one direction.
