Abstract

A conformal array with directive patch antenna element is designed and proposed to achieve optimum direction of arrival performance. The MUSIC method is used for the proposed array evaluation and compassion where the antenna radiation patterns extracted from the full wave simulation software are encountered in the DOA estimation process. Antenna mutual coupling and radome effect are among the radiation patterns used to achieve more precise results. The simulations results prove that conformal array achieves better DOA estimation performance than the planar array antenna especially in the horizontal plane. Moreover, the conformal antenna array angle is evaluated to achieve optimum conformal array structure.
