1. A phased array antenna comprising a plurality of unit cells arranged in an array,
wherein each of the plurality of unit cells comprises:
at least one radiating element receiving a feed signal and radiating a signal; and
two path changeover switches for transmitting the feed signal as it is or as a distribution to the at least one radiating element, or at least one unit cell disposed adjacent, under control of an antenna control circuit,
wherein each of the two path changeover switches operates in one of a forward mode in which the feed signal is transmitted in a forward direction, and a divide mode in which the feed signal is divided into two and transmitted in both side directions of the forward direction, under the control of the antenna control circuit,
such that the feed signal is transmitted to another path changeover switch in the same unit cell or the at least one radiating element or at least one adjacently disposed unit cell.
