Title:
ANTENNA AND ELECTRONIC DEVICE COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2021/045241
Kind Code:
A1
Abstract:
An electronic device comprising an antenna according to the present invention is provided. The electronic device comprises: a first antenna which is formed as a metal frame having a predetermined length and is configured so as to operate in first to third frequency bands; a second antenna which is distanced from the first antenna by means of a slit and is configured so as to operate in the second frequency band; a third antenna which is distanced from the first antenna by means of a second slit and is configured so as to operate in a band adjacent to the third frequency band; and a switch which is connected to the first antenna and controls such that a power feeding unit of the first antenna is connected to a ground by means of a particular port in accordance with a control signal and thus a resonant frequency of the first antenna changes. Therefore, by connecting the first antenna to a matching circuit connected to the power feeding unit, antenna performance is obtained even in a low frequency band of a low band (LB) and an interference between other antennas can be reduced.
