摘要：
A theoretical model to analyze the impedance and radiation characteristics of a slot fed by a parallel-plate waveguide 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 value is computed with the use of the Lorentz reciprocity theorem, whereas the radiation pattern is determined from the radiation of an equivalent magnetic current embedded in an infinite conductive surface. Experimental results on a prototype are given to validate the theoretical model. The data fit the predicted results well. (C) 1997 John Wiley & Sons, Inc.
