Abstract
Array pattern optimisation based on semidefinite programming is proposed to improve the coverage performance of cellular communications from High Altitude Platforms (HAPs). This optimisation, when applied to a linear vertical array of N omnidirectional antenna elements, allows a coverage performance better than that of an array of N narrowbeam aperture antennas forming hexagonal cells on the ground. In addition to performance enhancement, the HAP antenna payload can be significantly reduced.Keywords
