ANTENNA STRUCTURE AND METHOD FOR CALIBRATING SIGNAL

Title:

ANTENNA STRUCTURE AND METHOD FOR CALIBRATING SIGNAL

Document Type and Number:

WIPO Patent Application WO/2022/098172

Kind Code:

A1

Abstract:

An antenna structure comprises: a first antenna; a second antenna; at least one processor; a power distribution circuit for equally supplying power supplied from the at least one processor to the first antenna and the second antenna; and a coupler arranged between the at least one processor and the power distribution circuit, wherein the at least one processor may obtain a first parameter for a first signal received by the first antenna and a second parameter for a second signal received by the second antenna, detect a phase difference between the first signal and the second signal, obtain, from among the first parameter and the second parameter, matching parameters on the basis of parameters corresponding to a case where the phase difference meets specified conditions, and obtain, from among the matching parameters, a third parameter allowing a reflection coefficient of a signal coming from the power distribution circuit to the coupler, to be within a specified range.
