摘要

 Circuit and network approaches can be very useful for the development of microwave planar filters. In this talk several typical examples will be addressed. This includes a general circuit model for planar transmission line defected ground structures that exhibits multiple electromagnetic band gaps or stop bands in frequency responses. Another equivalent circuit of cross-coupled resonator filter with a transmission line-inserted inverter is introduced to investigate a generalized configuration of transmission line filter for realization of different advanced filtering characteristics. Narrowband cross-coupled filter designs are usually based on design parameters such as the coupling coefficient and external quality factor. To this end, equivalent circuit models can be deployed to establish useful relationships to extract these design parameters from full-wave EM simulated responses. Examples will be given for a demonstration. Equivalent circuits are also used to develop a new design method for an electronically reconfigurable wideband coupled line filter.  The new design procedure makes design of this type of reconfigurable filter easy while eliminating the need for an impedance transformer to improve wideband performance For the demonstration, the newly developed design procedure has been deployed to design a three-state reconfigurable wideband filter of this type and validated by both EM simulation and experiment. Lumped-element equivalent circuits are useful for developing miniature multilayer filters using liquid crystal polymer (LCP) technology, which are described.

报告人简介

The invited speaker, Professor Jiasheng Hong, received the D.Phil. degree in engineering science from the University of Oxford, UK, and is currently a professor at Heriot-Watt University, Edinburgh, UK, leading a team for research into advanced RF/microwave device technologies. Professor Hong has pioneered the development of advanced microwave planar filters and published over 200 technical papers in these areas as well as two internationally well-received reference books, i.e. Microstrip Filters for RF/Microwave Applications (New York: Wiley, 1st Edition 2001, 2nd Edition 2011) and RF and Microwave Coupled-Line Circuits, Second Edition (Boston: Artech House, 2007), which have the most significant impact on new microwave filter technologies such as the superconducting filters, multilayer filters based on liquid crystal polymer substrates, as well as reconfigurable or tunable planar filters. This also led to an explosion in the development of new filter topologies for narrow and ultrawideband applications.
  Professor Hong’s achievements have been recognized internationally in both microwave industry and academia. He has been presented the SELEX Galileo Innovation Award on Development of a University Partnership to Develop new RF Filter Technologies. He is an active member of IEEE MTT Technical Committee for Filters and Passive Components; the Associated Editor of IEEE Transactions on Microwave Theory and Techniques, and serves at Editorial board/Reviewer board of IEEE Microwave and Wireless Components Letters, Wiley International Journal of RF and Microwave Computer-Aided Engineering, and IET Proceedings, Microwaves, Antennas and Propagation. Professor Hong was the past Chairman of Technical Programme Committee for 2011 European Microwave Conference and is a Fellow of IEEE.
