Experimental validation of microstrip bend discontinuity models from 18 to 60 GHz

A cavity resonance technique is described and used to experimentally verify microstrip bend discontinuity models over the frequency range 18 to 60 GHz. A novel, dual-cavity method leads to elimination of confounding variables and permits isolation and investigation of the bend model alone. This cont...

Description
Summary:A cavity resonance technique is described and used to experimentally verify microstrip bend discontinuity models over the frequency range 18 to 60 GHz. A novel, dual-cavity method leads to elimination of confounding variables and permits isolation and investigation of the bend model alone. This contrasts to a more standard approach in which the presence of models for several other structures such as microstrip and a coupler complicates study of the specific model under consideration. Optimally mitered, 50% mitered and unmitered bends of three different widths on alumina are included.< >
