Abstract

This work deals with the properties of a long slot array fed by an array of periodically located feeds spaced at a Nyquist interval. The study begins with the rigorous Green´s function (GF) of a single long slot which was extended to an infinite array structure. After this, the input impedance properties of the array when fed by an array of δ sources are described by simple formulas, which explicitly show a theoretically unlimited bandwidth when there is no backplane.
