Abstract

The synthesis of circular antenna arrays to have arbitrary radiation patterns is investigated. The difference between the array factor and the desired radiation pattern is made minimum by the least mean squared error (LMSE) method. The desired pattern of circular arrays is likened to patterns of linear arrays. A matrix equation is obtained to determine the excitation currents. The performance of the proposed method is verified by some comprehensive examples.

Keywords: antenna array synthesis; circular antenna arrays; least mean squared error method

Abbreviations: FCE: Fourier's coefficients equating; LMSE: least mean squared error
