Summary:
Parasitic elements of half wavelength dipoles were proposed to be loaded between two apertures in the configuration of an array antenna with element apertures. Its objective is to bury the gaps, and to adjust the phase relation between the directly radiated wave from the element apertures and the scattered illumination wave by the dipoles. In this paper, the equivalence of an incident wave and voltage sources in infinitesimal gaps is deduced to clarify the aforementioned phenomena. The validity of the proposed idea will be shown through the simulation study of partly excited parasitic elements in various perspectives and through the comparison with experimental results. It will be greatly useful to the design of ultra-large antennas in the future to study partly excited parasitic elements by simulation method in addition to experiment.
