Abstract
Disclosed is an antenna element in which dual orthogonal feed ports connected to a radiating element are configured to perform angular rotation feeding without using a mechanical phase shifter, an array antenna employing the antenna element, and an operating method of the array antenna. The antenna element comprises a driving radiating element formed on one side of a circuit board and having multi-feed ports, a ground plane element formed on the other side of the circuit board; multi-feed via holes formed in the ground plane element to correspond to the multi-feed ports, multi-feed via pins inserted into each of the multi-feed via holes, and a reconfigurable feed circuit configured to control a radiation pattern of the driving radiating element by applying feed signals for dual orthogonal channels having a phase difference of 90° to two feed ports selected from among the multi-feed ports.
