Title:
DEVICE AND METHOD FOR IMPROVING RADIATION PERFORMANCE OF ANTENNA USING IMPEDANCE TUNING
Document Type and Number:
WIPO Patent Application WO/2018/221847
Kind Code:
A1
Abstract:
An electronic device according to various embodiments of the present invention comprises: a transceiver; a power amplifier; at least one antenna; a coupler; a memory for storing reference phase information; and a processor. The processor may be configured to: transmit an output signal of a designated frequency band by using the transceiver; amplify the output signal by using the power amplifier; radiate the amplified output signal via the at least one antenna; acquire, via the coupler, the amplified output signal and a reflected signal that is the amplified output signal having been reflected from the at least one antenna; identify a reflection coefficient on the basis of the amplified output signal and the reflected signal; on the basis of phase information corresponding to the reflection coefficient, identify a difference value between the phase information corresponding to the reflection coefficient and reference phase information, among items of reference phase information, corresponding to the designated frequency band; and compensate for another output signal to be transmitted through the transceiver, at least on the basis of the difference value. In addition, various embodiments are possible.
