【 摘 要 】

A technique for evaluation of conductor and dielectric losses in pedestal-supported finlines using mixed spectral domain approach has been presented. All field components were computed through application of Galerkin' s technique in spectral domain, assuming weighted basis functions to represent unknown electric voltages, i.e., magnetic currents. In the process, the propagation constant along the line was also accurately computed. The aim was to study attenuation behaviour of these lines wrt variation in dimensional and other structural parameters. The results indicated a specific dimensional range within which their use is justifiable. The potential defence applications of pedestal-supported finlines is in millimeter wave systems, e.g., radars, missile guidance systems, etc.
