摘要
To provide a patch array antenna that allows a limited increase in active component even if the number of antenna elements increases, in a first unequal distribution circuit 106, a first distribution ratio of the power of a first high-frequency signal to be distributed from a first feeding point 108 to first to Nth antenna elements is set to be one of monotone increasing and monotone decreasing with respect to a row of the first to Nth antenna elements. In a second unequal distribution circuit 107, a second distribution ratio of the power of a second high-frequency signal to be distributed from a second feeding point 109 to the first to Nth antenna elements is set to be the other of monotone increasing and monotone decreasing with respect to the row of the first to Nth antenna elements. Directivity is controlled by changing a phase difference between the first and second high-frequency signals.
