The amount of phase control realizable by resonant compound slots for application in a standing wave array is investigated. It is shown that with a proper choice of excitation coefficients, shaped beam antenna patterns can be designed with the use of resonant compound coupling slots. A procedure for designing resonant compound coupling slots in the feed waveguide of a planar array is presented. With the use of this procedure a shaped beam antenna pattern has been realized by a planar array consisting of compound coupling slots in the end-fed configuration and conventional longitudinal radiating slots. Excellent agreement between theory and experiment is found for input VSWR and radiation patterns, thus demonstrating the utility of resonant compound coupling slots
