A more comprehensive analysis of microstrip gap discontinuity in the spectral domain

This paper presents an effective method for calculating the equivalent circuit of the microstrip gap discontinuity. A capacitive /spl pi/ network model is used for representing the coupling between the two microstrip patches. Fullwave analysis of the microstrip gap discontinuity has been carried out in the spectral domain, and the equivalent /spl pi/-network has been determined as a function of the gap spacing for different patch widths.<>
