Parasitic array of two loaded short antennas

A double impedance loading technique is applied in the study of a parasitic array of two loaded short antennas, Approximate solutions for the currents in the array elements are obtained. It is demonstrated that the current distributions in the array elements can be appropriately modified by optimum impedance loadings to achieve significant improvement in radiated power or directivity. Theoretical predictions are verified closely by the results of an experimental study.
