Title:
ANTENNA DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/039408
Kind Code:
A1
Abstract:
In this antenna device (1), an antenna unit (4) is formed on a first surface of a dielectric substrate (2), and a base plate (3) is formed on the second surface thereof. The antenna unit has one or more antenna patterns (41) configured to act as radiating elements. By resonating in one or more resonance directions in response to incident waves having the operating frequency of the antenna unit, the antenna pattern generates polarized radiation waves different from the transmission and reception waves transmitted and received by the antenna unit. Further, for each of the resonance directions, the antenna pattern is provided with at least one path pattern (Pu, Pv) narrower than the total width of the antenna pattern in the direction perpendicular to said resonance direction.
