Microwave Filters: Class Photograph 2014

Course Information

Dates: 27-31 January 2014

Course code: EEE5117Z/EEE5118Z

Venue: Menzies Seminar Room, 6th Floor, Menzies Building (Upper Campus), University of Cape Town

Course Description

This intensive course is presented over five days and presents a systematic progression of topics from specification and theoretical synthesis, CAD-assisted design and practical manufacturing techniques for microwave filters operating in the frequency ranges of typical radar systems.

This course will be of benefit to all who require a solid foundation in microwave filter design, from basic concepts to advanced topics in filter synthesis and cutting-edge filter technologies. Students will be exposed to world-leading commercial EM software for the analysis of filter designs.

Course Overview

The following topics are covered:

  • How to select filters for various applications according to specifications, frequency ranges, trade-offs
    between performance and size.
  • Filter technologies: planar filters on conventional substrates, multilayer design and packaging
    techniques (LTCC and LCP) including quasi-lumped element filters, machined waveguide filters and
    substrate integrated waveguide, and monolithically integrated filters.
  • Design methods for narrow-band, wideband and multiband filters.
  • Manufacturing techniques, design-for-manufacture considerations, tolerance analysis and repeatability.
  • Full-wave EM solvers and design tools for filter design and optimization.


Prof Riana Geschke is an Associate Professor at the University of Cape Town where she teaches undergradute courses on Engineering Design Methodology, Applied Electromagnetics and Microwave Systems. At postgraduate level, she teaches a course on Technologies and Practical Design for Microwave Filters. Her group’s current research activities span the microwave frequency range from L-band to the 60 GHz communications band. The work is focused on multilayer planar filters, electronic reconfigurability and filters based on transmission lines with special properties. She participated in the FP7 Marie Curie IRSES MultiWaveS project, which focused on Electronically Reconfigurable Multiband Devices and has authored and co-authored a number of journal papers, conference presentations and book chapters in this field.

Riana Geschke’s academic and research career started while pursuing a PhD degree (completed in 2004) at the University of Stellenbosch (SU) in the field of Computational Electromagnetics. During that time, she became a Lecturer in the Department of Communications’ newly established Postgraduate Diploma in Engineering Programme. She was based at SU until the end of 2012, developing an interest in the field of passive microwave component design. In 2013, she thus joined the Radar and Remote Sensing Group at UCT to extend the group’s capabilities in terms of microwave and millimeter wave activities. This naturally complements the group’s current and planned projects and activities. Riana is a regular reviewer the IEEE Wireless and Components Letters and on the Editorial Board of the International Journal of RF and Microwave Computer‐Aided Engineering. She is also a Senior Member of the IEEE.

In South Africa, she is involved in activities to stimulate academic and industry collaboration by promoting interaction and collaboration between electrical engineers. In this regard, she is an IEEE volunteer and is currently on the Executive Committee of the South African IEEE Section. From 2009 to 2012, she was the chair of the joint Antennas and Propagation-Microwave Theory and Techniques and Electromagnetic Compatibility (AP-MTT-EMC) IEEE chapter in South Africa, and during that time also chaired the South African AP-MTT-EMC chapter conference in 2011. As a Specialist Editor for the SAIEE Africa Research Journal, she contributes to initiatives for local researchers to publish Electrical and Electronic Engineering research that has both local and international significance.

Tinus Stander is a Senior Lecturer at the Carl and Emily Fuchs Institute for Microelectronics, Department Electrical, Electronic and Computer Engineering, University of Pretoria.

He heads the mm-Wave Research Laboratory at CEFIM, where he leads research activities on microwave and mm-wave devices on-chip and on hybrid media. Apart from his role in academia, Dr Stander is also a practicing engineering consultant, where he specialises in compact RADAR and EW front-end devices and subsystems.
