Synthesis of Conical Phased Antenna Arrays Optimization of Amplitude Distribution Parameters

Abstract

In the synthesis of conical phased antenna arrays (CPAA), special attention is paid to its characteristics - a high antenna gain and a low side lobes level (SLL). To solve this problem there are a significant number of approaches, in view of the variety of methods of its formulation and the methods of solution. In the present paper, the problem of synthesis of a conical phased array is solved by optimizing the parameters of a two-parameter family of amplitude distributions by the criterion of maximum gain with the limit of the maximum side lobe limited by the methods of random search (based on a swarm of particles) and classical gradient methods. To calculate the loss function, a fast Fourier transform is used.
