Design of Antenna Arrays Using Chaotic Jaya Algorithm
Antenna arrays are commonly used in communication systems to enhance desired radiation properties. The optimum design of antenna arrays is an important problem as it greatly affects the efficiency of the communication system. In this work, a variation of Jaya algorithm, i.e., Chaotic Jaya, is used to design planar antenna arrays to get minimized side lobe levels (SLL) thus improving the directivity. Two design examples of planar antenna arrays (concentric circular and hexagonal) are formulated by considering different inter-element spacings. Comparison of results between Chaotic Jaya algorithm and few other algorithms is done to demonstrate the algorithm’s efficiency. The Chaotic Jaya algorithm was able to get much-reduced side lobe levels.
