Document Type and Number:
WIPO Patent Application WO/2023/136046
Kind Code:
A1
Abstract:
An antenna device (100) has a first patch antenna (110), a second patch antenna (120), and a short-circuit plate (130). The second patch antenna has a different resonance frequency from the first patch antenna (110). The short-circuit plate (130) causes one edge (110a) of the first patch antenna (110) and one edge (120a) of the second patch antenna (120) to be short-circuited to the ground. One edge (130a) of the short-circuit plate (130) connected to the one edge (110a) of the first patch antenna (110) and the one edge (120a) of the second patch antenna (120) has a shorter length than the one edge (110a) of the first patch antenna (110) and the one edge (120a) of the second patch antenna (120).
