TECHNOLOGY FOCUS
The steady growth in commercial interest in RF, micro-/mm-wave and Terahertz wireless communication networks and systems, especially in wireless communications such as 5G and Beyond/6G, Internet of Things (IoT), security and wireless sensor applications, and military and transportation electronics, has provided a significant challenge to conventional RF, micro-/mm-wave circuits and their design methodologies.
The fifth generation (5G) technology is one of the most hyped topics in technology with enthusiasts promising it will be the gateway to virtual reality (VR), augmented reality, the Internet of Things (IoT), 3D services, pervasive high-resolution video and self-driving cars. The development of wireless communication over the last three decades has revolutionized our lives. In the past decade there has been a proliferation of wireless services and devices, followed by increasing demands for higher data rates.
Many of new technologies will rely extensively on enhancements to Multiple-Input-Multiple-Output (MIMO) systems including systems such as mm-Wave cellular systems and massive MIMO. Recent advances in RF, micro-/mm-wave computer-aided circuit design technology suggest the feasibility of interfacing electromagnetic simulations directly to sophisticated optimization systems. With the availability of powerful computers this optimization-based approach to the design of RF, micro-/mm-wave circuits become a desirable tool. CAD has become an essential tool in the design and manufacturing of RF, micro-/mm-wave circuits and 5G and Beyond/6G wireless systems.

WHO SHOULD ATTEND
The methods described here are useful for anyone designing hardware or software for 5G and B5G/6G wireless communication and Internet of Things (IoT) systems. Postgraduate and final year undergraduate students, engineers, managers and scientists who need an expanded, up to date understanding of advanced 5G and Beyond/6G and IoT wireless system design.
Day 1.
The first day begins with a theoretical insight into 5G and Beyond/6G wireless communication systems, a review of 5G and Beyond Technology and wireless communication system design. Application of 5G and Beyond will be briefly reviewed. The sub-6 GHz (e.g. n77: 3.3-4.2 GHz; n78: 3.3-3.8 GHz; n79: 4.4-5.0 GHz) and mmWave (e.g. n261: 27.5-28.35 GHz; n257: 26.5–29.5 GHz; n258: 24.25-27.5 GHz; n260: 37-40 GHz) 5G frequency bands will be reviewed briefly. Day 1 continues with a study of a basic theory of high frequency filters, filter technologies, and filter design for 5G and Beyond wireless communication applications. The rest of the day will be devoted to waveguide and microstrip filter, diplexer and multiplexer synthesis, analysis and design procedures. The EPFIL software package developed by instructor seeks to improve waveguide filter and diplexer design and decrease performance variations without creating overly stringent manufacturing tolerances. The accompanying manual helps the reader to cut design time and improve accuracy by quickly and easily predicting performance parameters before building costly prototypes. Using the mode-matching method as a foundation, the software supplies a full-wave solution for filter discontinuities, aiding you in the design of E-plane waveguide filters specifically intended for RF, micro-/mm-wave 5G and beyond applications. This means you can substantially reduce development and production costs, reduce time-to-market, and effectively increase circuit performance.
