Title:
ANTENNA DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/039407
Kind Code:
A1
Abstract:
A base plate (3) is formed on a first surface of a dielectric substrate (2), and an antenna unit (4) is formed on the second surface thereof. The antenna unit has one or more antenna patterns (41). An additional function unit (5) has multiple conductor patterns (51) arranged around the antenna unit. By resonating in one or more resonance directions in response to the incident waves having the operating frequency of the antenna unit, the multiple conductor patterns generate radiation waves comprising polarized waves separate from the transmission and reception waves of the antenna unit. For each of the resonance directions, at least one of the conductor patterns is provided with at least one path pattern (Pu, Pv) narrower than the total width of the conductor pattern in the direction perpendicular to said resonance direction.
