Design and Synthesis of Circular Antenna Array Having Elements Controlled by Linear Actuators

In this paper, a reconfigurable circular antenna array design whose elements are driven by linear actuators is proposed. The radial position movements of the array elements are realized by means of the actuators to synthesize the desired radiation pattern. The position perturbations of each element are calculated by using classical differential evolution algorithm. Different radiation patterns with single, double and wide nulls are successfully achieved in reasonable maximum iteration numbers.
