Xu, Z., Zakharov, Y. and White, G. (2007) Antenna array optimisation using semidefinite programming for cellular communications from HAPs. Electronics Letters. pp. 67-69. ISSN 0013-5194
Array pattern optimisation based on semidefinite programming (SDP) 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 the performance enhancement, the HAP antenna payload can be significantly reduced.
