Optimal Aperiodic Microstrip Antenna Array with Main Lobe Tilting, Null Filling and Low Sidelobe Level by Using PSO with Velocity Mutation

Description

Several techniques have been proposed so far for the design of base station antenna arrays in order to satisfy multiple requirements, which are mandatory in broadcasting applications. Such requirements are: (i) a maximum forward gain to enhance the reception at long distances, (ii) main lobe tilting, as the base station is often located at places higher than the service area, (iii) null filling inside an angular sector under the main lobe, as the directional gain must not fall under a specific value for proper reception, and (iv) a standing wave ratio (SWR) under a certain value, so power is not wasted inside the feeding network of the antenna array. Obviously, the satisfaction of these requirements is a multi-objective
problem and is efficiently solved when using evolutionary algorithms.
