“…In the case of circular arrays with directional elements, when the element pattern and array pattern are not separable, numerical techniques have been applied [3,4]. A phase mode analysis has been carried out when the directional elements can be approximated by a cosine pattern [5,6].…”

“…A signal entering one port of the Butler Matrix is divided into equal parts before the signal is amplified by all the amplifiers and then recombined by the combining Butler Matrix at the output port that corresponds to the particular input port. Suarez also used a Butler Matrix in his research [15,16]. He reported a uniform narrowbeam switched array antenna system of up to eight beams, produced by means of cascaded passive Butler Matrices.…”

“…In this article, a new approach is proposed for obtaining the radius of the CAA by utilizing the phase mode concept. The mathematical equations governing the phase mode concept for CAA with both isotropic and directive elements are clearly described and reported [14,[19][20][21][22]. Various deterministic procedures on antenna arrays suggest various synthesis procedures for far-field analysis [23][24][25][26][27].…”

Abstract-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.
