This paper proposes the concept of sparse appended with the space tapering technique for the synthesis of an antenna radiation pattern. The procedure experiments on a Circular Antenna Array (CAA) configuration comprising of directional element (1+cos(φ )). The sparse initiates the minimum number of active elements in the CAA, while the space tapering technique gives the complex excitations that yield a beam pattern with constraints such as Side Lobe Level (SLL) and Beam Width (BW) in relation to Dolph-Chebyshev radiation pattern. The phase mode analysis, which is an built-in procedure in the proposed technique explores the circular antenna array configuration characteristics. The simulation results justify the effectiveness of the proposed technique for obtaining the desired radiation pattern synthesis.
