Process and apparatus for communicating with user antenna phased arrays
First Claim
1. A system for forming a plurality of simultaneous communication signals having an operating wavelength comprising (a) a plurality of phased array antennas each mounted on a respective high altitude platform (HAP) and (b) a phased array antenna mounted on user equipment at a lower altitude than that of the HAPs wherein the phased array mounted on the user equipment has operating antenna elements, the centres of which are spaced from their nearest operating antenna element centres by more than 1.2 times the operating wavelength and the phased arrays mounted on the HAPs have operating antenna elements, the centres of which are spaced from their nearest operating antenna element centres by more than 1.2 times the operating wavelength.

Abstract
The use of phased array antennas in ground based or low altitude user equipment linked to high altitude aerial platforms also utilizing sparse phased-array antennas (uniform and non-uniform), which enables the delivery of information services, including telecommunications, earth observation, astronomical and positioning services with higher data rates, lower weight, power consumption and sidelobe levels than for other antenna arrangements.
