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 beamforming 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. The study of the coverage performance for the three different types of weights is introduced. Results indicate the superior performance of PSO in improving the coverage performance than Dolf-Chebyshev and Hamming windows.
