Abstract：This paper first presents the unified network model associated antennas with loaded networks, which shows that the loaded circuit networks and the antennas (field networks) are unified by the generalized matrix Ohm’s law. Based on the theory of the unified network model, this paper give a rigorous study of the Five-element Circle Array for Direction Finding (FCADF) by using the Method of Moments (MoM). The results show that the interaction between circuits and fields is introduced by loading a matching and compensating network, which compensates the effect of mutual coupling between array elements, realizes impedance matching, and improves the non-circular degree of radiated pattern and the precision of direction finding. In addition, the local resonant phenomenon in FCAFD is effectively restrained by loading the circuit network.
