Abstract
A communication system includes an array of RF elements that transit and/or receive signals through a lens, and a power divider is configured to provide unequal amplitude and/or phase to at least some of the RF elements. In transmit mode, the shape and direction of the resulting beam is controlled in part by the shape of the array, the relative power distributed to the different RF elements, the operating frequency, the shape of the lens, the position of the lens with respect to the array, and the distance of the lens from the array.
Claims14
A communication system comprising:
- a lens illuminated by an array having a first set of at least two RF elements aligned along a first axis, and a second set of at least two RF elements aligned along a different, second axis, wherein the first and second axis intersect;
- wherein the first set of RF elements is configured to apply a first weight set and the second set of RF elements is configured to apply a different second weight set;
- and
- wherein concurrent application of the first weight set by the first set of RF elements and the second weight set by the second set of RF elements to illuminate the lens produces a rectangular shaped beam pattern.
