ELECTRONIC DEVICE COMPRISING ANTENNA

WIPO Patent Application WO/2023/195606

A1

According to various embodiments disclosed herein, an electronic device comprises: a wireless communication circuit; an antenna; a matching circuit disposed between the wireless communication circuit and the antenna; and a processor operatively connected to the wireless communication circuit, the antenna, and the matching circuit. The matching circuit includes: a first switching circuit; a second switching circuit; a first inductor connected between a 1-2nd node and a ground; a second inductor connected between a 1-4th node and the ground; a third inductor connected between a 2-4th node and the ground; a first electrical path electrically connecting the first switching circuit and the second switching circuit; a plurality of capacitors disposed between the wireless communication circuit, the first switching circuit, and the second switching circuit; a second electrical path connecting the first electrical path with one of the plurality of capacitors; a third electrical path connecting a 2-2nd node and a feeding point of the antenna; and a bypass line connected to a 2-1st node. The first switching circuit includes: a first switching element that is connected to a 1-1st node and switches the connection with the ground; a second switching element connected between the 1-1st node and a third node; a third switching element that is connected to the 1-2nd node and switches the connection with the ground; a fourth switching element connected between the 1-2nd node and the third node; a fifth switching element that is connected to a 1-3rd node and switches the connection with the ground; a sixth switching element connected between the 1-3rd node and the third node; a seventh switching element that is connected to the 1-4th node and switches the connection with the ground; and an eighth switching element connected between the 1-4th node and the third node. The second switching circuit includes: a ninth switching element that is connected to the 2-1st node and switches the connection with the ground; a tenth switching element connected between the 2-1st node and the third node; an eleventh switching element that is connected to the 2-2nd node and switches the connection with the ground; a twelfth switching element connected between the 2-2nd node and the third node; a thirteenth switching element that is connected to a 2-3rd node and switches the connection with the ground; a fourteenth switching element connected between the 2-3rd node and the third node; a fifteenth switching element that is connected to the 2-4th node and switches the connection with the ground; and a sixteenth switching element disposed between the 2-4th node and the third node. The processor may be configured so as to be able to: when a wireless signal is input, apply the wireless signal to at least one of the plurality of capacitors; control to turn on or off the plurality of switching elements of the first switching circuit and the plurality of switching elements of the second switching circuit on the basis of the wireless signal being applied to the at least one capacitor; and operate the matching circuit as a serial variable capacitor and a parallel variable capacitor on the basis of the plurality of switching elements of the first switching circuit and the plurality of switching elements of the second switching circuit being controlled to be turned on or off. Various embodiments other than those disclosed in the present document may be possible.
