Abstract:
1. An antenna array, comprising: a nested plurality of coaxial geodesic lenses, each said geodesic lens having a radial feed element array disposed at equal intervals around a proximate end of each said geodesic lens, the radial feed element array comprising a plurality of feed elements disposed in a feeding ring coaxial to the nested plurality of coaxial geodesic lenses; and a feed network operably connected to each said feed element array, said feed network comprising a plurality of adjustable phase shifters and gain elements providing separate gain and phase control to each respective geodesic lens in the nested plurality of lenses, such that each geodesic lens forms, for the antenna array, an elevation element having separate gain and phase control; wherein said adjustable phase shifters and gain elements are independently and simultaneously controlled to independently form and steer, in both azimuth and elevation at the same time, at least one beam radiated from the distal end of said nested plurality of coaxial geodesic lenses.
