Abstract
A technique for phase-up of array antennas of regularly spaced lattice orientation, without the use of a nearfield or farfield range. The technique uses mutual coupling and/or reflections to provide a signal from one element to its neighbors. This signal provides a reference to allow for elements to be phased with respect to each other. After the first stage of the process is completed, the array is phased-up into, at most, four interleaved lattices. These interleaved lattices are then phased with respect to each other, thus completing the phase-up process.
