Abstract:
1. An antenna having radiator elements arranged on different planes, comprising: a first-position radiator element placed at one plane; a second-position radiator element placed at another plane; and power supply cables connected to the first-position radiator element and the second-position radiator element, wherein lengths of the power supply cables are configured to compensate for a phase difference between signals radiated in the air from the first-position radiator element relative to the second-position radiator element by a phase difference between the power supply cables according to a position difference between the planes at which the first-position radiator element and the second-position radiator elements are placed; wherein a signal phase difference from the first-position radiator element to the second-position radiator element is calculated by subtracting a phase difference between the first-position radiator element and the second-position radiator element in the air from a phase difference between the first-position radiator element and the second-position radiator element on the power supply cables.
