Abstract

This paper investigates the effects on received mutual coupling of λ/2 dipole arrays placed near real-earth. As a rule of thumb, estimation of mutual coupling can be divided in two regions of antenna height that is very near ground 0 < h < λ and fairly freespace region h ≥ λ. The receiving antenna mutual coupling remains fairly unaffected from ground conductivity, when antenna height h ≥ λ. Both vertical and horizontal polarization cases showed the same trend. Investigation of effects of nearness of good-ground to the array on DOA estimation revealed that for azimuth DOA estimation, the proposed method of removing mutual coupling works well even for near ground.
