Multi-faced and multibeam DBF antenna for high altitude platforms station stages of antenna development

Advantages of the multi-beam antenna for Stratospheric Communication System (or HAPS) with digital beam forming (DBF) are demonstrated in comparison with analogue beam forming (ABF). To cover the service area from nadir to a circle of radius 55 km by 199 beams, the antenna system of seven flat activ...
