The design of transverse slot arrays fed by the meandering strip of a boxed stripline

Transverse slots fed by a boxed stripline, with the strip passing centrally under the slot at an angle which controls the coupling, have been investigated theoretically and experimentally. A procedure has been developed which permits the design of arrays of such slots, including the effects of external mutual coupling. Agreement between theory and experiment has been found to be good for both a single slot and a linear array.
