Title:
ANTENNA APPARATUS AND COMMUNICATION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/053865
Kind Code:
A1
Abstract:
According to the present invention, an inner surface of a housing has a first region and a second region that are connected via a first corner portion. A first antenna element accommodated in the housing faces the first region spaced apart therefrom, and a second antenna element faces the second region spaced apart therefrom. A first waveguide is directed from the first antenna element toward the first region, and a second waveguide is directed from the second antenna element toward the second region. An end surface of the first waveguide on the side of the inner surface of the housing is positioned closer to the first corner portion than an image of an end surface of the first waveguide on the side of the first antenna element captured perpendicularly to a virtual plane including the first region. An end surface of the second waveguide on the side of the inner surface of the housing is positioned closer to the first corner portion than an image of an end surface of the second waveguide on the side of the second antenna element captured perpendicularly to a virtual plane including the second region.
