Abstract: The disclosure relates to an array antenna, and more specifically, the array antenna configured by arranging a plurality of antenna elements at close positions. An array antenna is provided. The array antenna includes a first antenna operating in a first mode, and a second antenna operating in a second mode, wherein a correlation between an electric field of the first mode and an electric field of the second mode falls below a first threshold which is predetermined, or a correlation between a magnetic field of the first mode and a magnetic field of the second mode falls below a second threshold which is predetermined.

Abstract: There is disclosed a method which is capable of calibrating or tuning the characteristics of individual antenna elements constituting an array antenna. The performance of the individual antenna elements can be improved by calibrating or tuning the characteristics of the individual antenna elements, and thus an array antenna can be installed even in a narrow space and can receive GPS signals.
