Jf. Carpentier et al., QUASI-STATIC ANALYSIS OF SKEWED TRANSMISSION-LINES FOR MMIC APPLICATIONS, IEE proceedings. Microwaves, antennas and propagation, 141(4), 1994, pp. 246-252
The capacitive coupling between two microstrip lines crossing diagonal
ly above a ground plane in a multilayered dielectric substrate is anal
ysed through a quasi-static approach based on the space domain integra
l equation method. The typical evolutions of the normalised lumped exc
ess capacitances for non-orthogonal crossover configurations are prese
nted and numerical results for an' orthogonal crossover are compared w
ith previously published data.
