  • Patent number: 11791552
    Abstract: A center-fed array antenna comprises: a central radiation element located in the center among the odd number of N radiation elements; a first radiation part including n (=(N?1)/2) first radiation elements positioned on one side of the central radiation element and n first phase shifters corresponding to each of the n first radiation elements; a second radiation part including n second radiation elements positioned on the other side of the central radiation element and n second phase shifters corresponding to each of the n second radiation elements; and a 3-way power divider distributes the received feed signal in an asymmetric ratio in proportion to the ratio of the number of radiation elements included in the central radiation element and the first and second radiation parts, and outputs the obtained first to third distribution feed signals to the corresponding central radiation element and the first and second radiation parts, respectively.
