Document Type and Number:
WIPO Patent Application WO/2021/153215
Kind Code:
A1
Abstract:
This antenna device (101) comprises a first antenna (1) and a second antenna (2). The first antenna (1) includes a coupling element (3), a phase adjuster (13), a first radiation element (11), and a second radiation element (12). Then, the phase adjuster (13) is provided so that a phase difference between signals of the first radiation element (11) and the second radiation element (12) in a communication band of the second antenna (2) is 180° ± 45°. With this configuration, obtained are: the antenna device (101) that secures isolation between a wideband antenna and an antenna for a frequency band adjacent to a frequency band used in this wideband antenna; and an electronic apparatus including the antenna device (101).
