Corporate Feed System for Cylindrical Antenna Array.

The patent relates to a reciprocal corporate microwave feed network. A matrix is connected between a selector switch and an antenna ring array. The matrix divides microwave energy from sender apparatus and produces a tapered phase distribution to a selectively predetermined sector of the array. The active or energized array sector forms a highly directive beam which is normal to the array sector. The matrix is circularly symmetric and can feed any sector of the array as selected by an input switch. The beam is step scanned over 360 degrees with the number of steps being determined by switching and matrix circuitry.
