DOA estimation using array antenna with arbitrary geometry
Qiaowei Yuan, Qiang Chen, Kunio Sawaya · 2005
A so called universal steering vector (USV) for array antennas with arbitrary geometry is derived to estimate the direction of arrival (DOA) by multiple signal classification (MUSIC) algorithm. Since the USV includes the effect of the mutual coupling between the array elements with arbitrary geometry, any additional manipulation for the received signals is not required to estimate the DOA. The USV is evaluated by the help of the full wave numerical analysis using the MoM. Numerical examples of the DOA estimation are presented for the cases of a dipole array antenna and an array antenna composed of a monopole antenna and a planar inverted-F antenna (PIFA) mounted on a mobile handset to demonstrate the high accuracy of the proposed method.
