Thinned Concentric Circular Array Antenna Synthesis Using Seeker Optimization Algorithm

A new approach for diminution of side lobe Ratio or level (SLL)maximum with half power beam width (HPBW) of thinned large multiple concentric circular antenna of the uniformly exuberated isotropic element, is proposed. Itis a novel optimization algorithm based on Seeker Optimization Algorithm (SOA) is used. Concentric Circular Antenna Array (CCAA) has been greatly recognized within subject of base radio station of the radio and telecommunications system. Since it has a 360-degree scan around its focus, beam pattern and all-azimuth scan capability, it has numerous advantages over other array geometries. A 9 ringed CCAA with a central element feeding is taken into consideration. CCAA which is having isotropic elements is examined by this algorithm and is shown appropriate.. Optimization efficiency is justified by antenna array synthesis, which is the result of themassive simulation. In all the cases mentioned in the paper, relative sidelobe level (SLL) is less than -20 dB with fixed HPBW compared to case of a uniform array. By using SOA with isotropic elements, the results of the simulation depict the amount of effective antenna elements can be pared from 279 to 120 with consistent abatement in side lobe ratio by 21.04 dB relative to that of the main beam with a fixed HPBW. Standard Particle Swarm Optimization (PSO) is used here to scrutinize outcome of SOA.
