The effects of mutual coupling within antenna arrays on angle of arrival methods
In this paper, a conical helical ring antenna array is proposed for detecting direction of arrival (DOA). This array is applied two angles of arrival (AOA) methods. These are minimum variance distortion-less response (MVDR) and MUSIC. The effect of mutual coupling is included on the estimation accuracy of angle of arrival. Six and eight elements ring antenna array with different spacing are studied. Results are presented that include the estimation error before and after compensation of mutual coupling.
