In a High Altitude Platform (HAP) cellular communications network, each cell may be served by a dedicated spot‐beam antenna. The antennas’ beam properties and their spatial overlap control the co‐channel interference. In prior literature, radiation patterns have been approximated by a main lobe followed by a constant sidelobe floor. A network of 121 cells has been studied and the method is here extended to the use of more realistic radiation patterns based on the theoretical aperture antenna patterns. This allows for the comparison of the effect of different aperture field tapers, which lead to reduced sidelobe levels and hence higher system capacity but also a more massive antenna payload.
