SPACE DOMAIN ANALYSIS OF MICRO-IDG STRUCTURES

The Microstrip Loaded Inset Dielectric Waveguide has been proposed as a transmission medium alternative to microstrip, and as a useful anten na medium at X-band and millimetric frequencies. In the present analys is we consider the case where a multi-layer, multi-conductor microstri p circuit may be housed within Inset Dielectric Waveguide. A generalis ed Transverse Resonance Diffraction method is developed in the space d omain for analyzing such structures. Experimental and theoretical resu lts for the propagation characteristics of the fundamental and first h igher order mode of a few different configurations are presented showi ng good agreement.
