The objectives of the proposed research are to advance the knowledge and applications of computer aided design (CAD) in high frequency systems, and to develop advanced and innovative microwave and millimeter-wave passive devices using different technologies. The emphasis will be the efficient design of filters, diplexers and multiplexers, focusing on the following areas. (1) For the design of multiplexing networks, which are widely used in communications satellites, highly efficient, robust and flexible design methodologies will be developed enabling overall multiplexer performance enhancement without resorting to more expensive technologies. (2) A combination of different techniques, such as neural networks and distributed circuit models, will be employed to accurately and quickly model filter/multiplexer behavior over a wide frequency range, to enable modeling, optimization and compensation of non-ideal effects, such as dispersion and spurious mode interference. (3) To find a low loss, low cost and highly integrated solution for millimeter-wave systems, Integrated Passive Devices (IPD) technology will be explored for the development of high quality filters and diplexers. Integration with other devices in the system, such as active devices and on-chip antenna, will also be investigated. Microwave/millimeter-wave passive devices have extensive applications, such as space and ground based communication systems, sensors and automotive radar. The proposed research program is expected to make significant contributions to the field of CAD, filter and multiplexer technologies, and integrated passive devices, in both theoretical research and practical applications. The outcomes of the research can enhance competitiveness of the Canadian high-tech industry in the global market through development of innovative technologies and improvement of design capabilities. Furthermore, the expertise gained by HQP in the research program is valuable to Canadian industries, especially the information and communication technology industry.
