Document Type and Number:
WIPO Patent Application WO/2022/209053
Kind Code:
A1
Abstract:
A multi-antenna (1) includes: a columnar body (12) extending in a first direction; a first antenna (10a) positioned at an end in the first direction along a lateral surface of the columnar body; and a second antenna (10b) positioned above the first antenna (10a) along the lateral surface of the columnar body so as to be aligned in the first direction. The first antenna (10a) is configured to radiate electromagnetic waves upon entering a mode in which artificial magnetic wall characteristics are exhibited for electromagnetic waves that are in a first operating frequency band. The second antenna (10b) is configured to radiate electromagnetic waves upon entering a mode in which artificial magnetic wall characteristics are exhibited for electromagnetic waves that are in a second operating frequency band different from the first operating frequency band.
