Antenna structure and method for signal calibration

A correction method for optimizing antenna performance, comprising:

• obtaining a first parameter for a first signal and a second parameter for a second signal;
• detecting a phase difference between the first signal and the second signal according to the obtained first parameter and the second parameter;
• obtaining matching parameters, based on parameters corresponding to cases in which the phase difference satisfies a specified condition among the first parameter and the second parameter;
• and
• obtaining a third parameter for allowing reflection coefficients of the first signal and the second signal to exist within a specified range among the matching parameters.

An electronic device comprising:

• a housing, wherein the housing comprises:
• a first part;
• a second part;
• and
• a connecting part disposed between the first part and the second part, the first part being coupled to the connecting part so as to be rotatable with respect to the second part;
• a first antenna including a first portion of the first part;
• a second antenna including a second portion of the second part, a first point of the first antenna corresponding to a second point of the second antenna when the housing is folded;
• at least one processor;
• a power distribution circuit configured to equally supply power supplied from the at least one processor to the first antenna and the second antenna;
• and
• a coupler disposed between the at least one processor and the power distribution circuit, and
• wherein the at least one processor is configured to:
• 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 matching parameters, based on parameters corresponding to cases in which the phase difference satisfies a specified condition among the first parameter and the second parameter;
• and
• obtain a third parameter for allowing a reflection coefficient of a signal flowing from the power distribution circuit to the coupler to exist within a specified range among the matching parameters.
