J. Martel et al., EQUIVALENT-CIRCUITS FOR MICROSTRIP GAP DISCONTINUITIES WITH METALLIZATIONS OF RECTANGULAR AND TRAPEZOIDAL CROSS-SECTIONS, Electronics Letters, 29(23), 1993, pp. 2052-2054
Microstrip gap discontinuities with finite thickness conducting strips
of rectangular and trapezoidal cross-sections are analysed. The finit
e thickness strips are modelled as pairs of equipotential strips of ne
gligible thickness placed at the top and bottom surfaces of the thick
strips. The excess charge technique in the spectral domain is used to
compute the quasistatic equivalent circuits of the analysed microstrip
gap discontinuities.
