Synthesis of Circular Array Antennas Using Accelerated Particle Swarm Optimization

In this paper, the design and synthesis of Circular Antenna Array Configuration (CAAC) is performed using the Amplitude-Spacing technique. The synthesis process uses the novel evolutionary computing tool known as Accelerated Particle Swarm Optimization (APSO). A 25 element and 50 element CAAC is designed with objectives like sidelobe level (SLL) suppression with beam-width (BW) constraints. While mitigating the inter-element spacing, the constraint on the circumference of the circle is also imposed. Analysis based on the results in terms of radiation pattern in which the SLL and BW are computed. The whole simulation is carried out in MATLAB.
