Full Wave Analysis Of Narrow Slot In The Ground Plane Of The Microstrip Line

A general approach to derive a solution method for the problem of microstrip line with an inclined slot in the ground plane is presented. The formulation is based on the Galerkin's method to find the unknown electric field which is generated in the slot area. Using the spectral domain transformation, reciprocity theorem and some other techniques such as integral transformation, a full wave solution for this configuration is obtained. Effects of various parameters such as slot dimensions and inclination are studied. Finally computed results are compared with measurements and previously computed data.
