Concentric Ring Shaped Cellular Configuration for High Altitude Platforms Using Particle Swarm Optimization

In this paper, a High Altitude Platform (HAP) based vertical One Dimensional (1D) antenna array is used to generate a concentric ring shaped cellular configuration. The geometry and the design of the ring shaped cells are explained. Different types of weights for the linear array, e.g. the Dolph-Chebyshev weights, Hamming weights, and optimized weights by the Particle Swarm Optimization (PSO) algorithm are used for beam-forming of the linear array. Calculations of the link budget are introduced for evaluating the signal to interference ratio SIR of a user in the HAP system.
