Abstract
In this paper, the shaped beam cylindrical array is presented to obtain full angular scanning in the plane of the array. This array antenna is designed such that it produces sum and difference radiation patterns simultaneously. The array elements are wideband printed dipole antennas which operate in L- frequency band. To design of the array antenna at first step, certain numbers of the elements (16 elements) in a sector of the cylindrical array (active area) are used to synthesize by the Particle Swarm Optimization (PSO) method. In the second step to rotate the optimum radiation pattern extracted from the first step, appropriate feeding network is suggested to rotate the active area around the cylindrical array axis. Therefore the radiation patterns of the array antenna remain completely constant in all scan angles.
