In this paper, a novel pyramidal shaped antenna configuration for two-dimensional direction-of-arrival estimation is presented. The proposed antenna consists of four sub-arrays and a top antenna for phase reference, and uses four antenna elements in DOA estimation with 4-channel receiver. The performance of 2D-DOA estimation based on sub-arrays of the proposed antenna under LOS environment is demonstrated.
