ABSTRACT:
In a phase-controlled antenna array for mobile devices, in particular designed for flying device, groups of controllable passive antenna elements are arranged in concentric circles around an active central antenna element. The arrangement of additional similar planar antenna arrays among the original antenna array is especially advantageous with regard to bundling the emission characteristic.
