Pattern Magnitude Synthesis for a Reactively Loaded Circular Antenna Array.

摘要

This report presents a method for synthesizing a given radiation field magnitude pattern for a reactively loaded circular dipolar array. The reactively loaded circular dipole array has the center dipole fed and the outer dipoles parasitically excited with reactive loads across their input terminals. Both seven and thirteen element arrays are considered. A Rosenbrock optimization algorithm is applied directly to the synthesis error function to determine the reactive loads required for minimum error. Any arbitrarily shaped magnitude pattern can be treated. The pattern magnitude synthesis results for the reactively loaded array are compared to that of an optimally excited array. A computer program for the optimization algorithm with operating instructions is included. (Author)
