    Optimizing circular antenna arrays with artificial rabbits optimization for beam control and side lobe reduction by Sunil Kumar, Harbinder Singh, Avtar Singh

    Published 2025-08-01
    “…Furthermore, several conventional techniques can be used to synthesize the array for real-time implementation, but they encounter difficulties in retaining the low SLL along with the narrow beam width. An optimization problem is formulated in this research work to achieve the necessary orientation of the main lobe, suppress the SLL, and achieve the requisite beam width. …”
