Abstract :
A new method for synthesizing non-φ-symmetric patterns radiated by planar antenna arrays with circular boundary is presented. The synthesis procedure uses the modified Taylor expressions but turning aside their inherent rotational symmetry, to provide appropriate non-φ-symmetric patterns. It allows selecting among complex excitation control or phase-only control in order to fulfill the design requirements.
