Synthesis of Pencil-beam Patterns with Time-modulated Concentric Circular Ring Antenna Arrays

摘要：

　　In this paper,a method for the synthesis of pencil beam patterns from time modulated circular ring antenna arrays is presented.The time modulation approach is applied to the uniformly excited concentric circular ring array(CCRA)to suppress the sidelobe level with fixed beamwidth.Based on the proposed method,some numerical examples are compared with the published results of the conventional concentric circular ring arrays.Numerical results show the achievable performance of time modulation in successfully synthesizing low sidelobe patterns even if the amplitude excitations are uniform.
