Summary:
In this paper, a novel array antenna for DOA estimation systems using a phase mono pulse mechanism is proposed. The proposed array antenna consists of patch elements and a both-sided feed line circuit including Magic-T circuits. In the DOA estimation, the arrival angle is obtained by sum and difference of received signals on two pairs of patch elements. The proposed array antenna estimates arrival angle by taking the power ratio of the sum and difference which are easily obtained using the simple Magic-T circuit.
