Mutual Coupling Compensation for Direction-of-Arrival Estimations Using the Receiving-Mutual-Impedance Method

Table 1

DOA estimation using MPM using a ULA with 8 antenna elements with the element separation of Δ=0.3𝜆. DOA estimation is based on the decoupled voltages using RMI determined based on methods 2 and 3.
