✦ Synopsis

A theoretical model to analyze the impedance and radiation characteristics of a slot fed by a parallel-plate wa¨eguide is presented. The slot is excited by a TEM mode propagating between the parallel plates and its effect is simulated by a series impedance in a transmission line. Its ¨alue is computed with the use of the Lorentz reciprocity theorem, whereas the radiation pattern is determined from the radiation of an equi¨alent magnetic current embedded in an infinite conducti¨e surface. Experimental results on a prototype are gi¨en to ¨alidate the theoretical model. The data fit the predicted results well. ᮊ
