Abstract:Millimeter waves have recently emerged as a practical frequency range for a wide variety of applications. System integration at these wavelengths offers many potential advantages while creating some unique challenges. This thesis is a two-part study of the feasibility of a special class of integrated circuits called dielectric waveguide-based integrated circuits. The first phase deals with the theoretical analysis and characterization of dielectric waveguides suitable for circuit integration. The second part is an intensive investigation of dielectric-based integration schemes and design, fabrication and testing of the components needed for the systems.
Existing theoretical analyses of dielectric waveguides are often inadequate for accurate determination of their characteristics over an extended range of operating parameters, particularly for higher-order modes. Such characterization is essential for designing many active and passive components based on dielectric waveguides. The present approach uses a field expansion technique, which generates the solution for all the propagating modes in the form of a determinantal eigenvalue equation. The open waveguide is analyzed as a limiting case of its shielded version. Computed results for a variety of dielectric image guides are presented. Several tests are incorporated within the computational module to ensure accuracy and reliability of solutions. Excellent agreement with experimentally measured results is noted.
The experimental work reported here entails the development of individual dielectric-based components, both active and passive, for eventual integration into communication or radar systems. Construction details and performance characteristics of some complete systems developed in this phase are provided. The design and fabrication exhibit considerable departure from the standard metal waveguide technology. The goal of total monolithic integration was given highest priority in this work. The viability and suitability of dielectric-based integration have been established in this investigation. Recommendations for future developments are presented.
