Abstract :
In this paper the ultrawide-band properties of a long slot array are described. The study provides the rigorously derived Green´s function (GF) for an infinite long slot array. From these GF active impedances and radiation patterns for various cases were obtained. The ultrawide bandwidths and the array performances of such apertures are highlighted, providing physical insights to understand the mathematical formulation throughout the paper.
