In late January, the 2024 IEEE Radio and Wireless Week (RWW) conference convened in San Antonio TX, gathering microwave and radio-frequency engineers to discuss the latest and greatest innovations in the field. Amongst the 139 technical papers and journals, plenary sessions, and three panel sessions, several key themes stood out that highlight the future of the RF/microwave field.

This article takes a closer look at two of these sessions and provides readers with a summary of what was learned and discussed at the conference. In addition, the greater trends in the microwave community are discussed to help determine where the focus and challenges may be shifting in the next few years.
RFID-Enabled Digital Twins
In the age of data and AI, it only makes sense that digital twins are a hot topic even in the RF community. In essence, a digital twin allows for continued development and analysis of a deployed system, without needing to travel to the deployment site to take measurements. As a result, designers can get near instant feedback on the performance of their devices, even while in the field, making the topic worthy of a panel session at RWW focusing on RFID and digital twins.
In order to enable this technology, however, RFID has been considered thanks to its ability to “match” a physical and digital twin. In addition, the addition of microwave sensors allows for precise measurements to be taken in tandem.
While in the grand scheme of things RFID is still quite new, in terms of engineering technology, it is quite robust, with panel member C.J. Reddy, VP of Business Development at Altair giving a vivid example.
“This is my bag tag from Delta, and if you open it, it has RFID. It tells you when your bag is checked in, and it actually tells you when it is coming on the conveyor belt.”
That example, though comparatively “low-tech” compared to some existing RFID technologies, highlights the maturity of the technology and its suitability for digital twins.

Reddy, Eduardo Rojas, and Jasmin Grosinger discussed the potential for RFID to be used in digital twins and discussed a range of applications from infrastructure monitoring to predictive maintenance.

RFID is not a perfect solution, however, with many concerned about the logistics of implementing digital twins at a large scale. While RFID can afford to be inefficient in one-off cases, the move toward dense deployments requires major improvements in sensor and transceiver efficiency.
That was highlighted by Nuno Borges Carvalho, Director of DETI and Universidade de Aveiro, who said “I believe that to have a massive deployment of these sensors we need to increase the efficiency of all of our systems.”
Pushing Moore’s Law Back
Moving to another topic, the RWW plenary sessions included highly topical discussions on industry trends. Specifically, Madhavan Swaminathan, Professor at Georgia Tech, discussed how advanced RF packaging will be critical to sustaining continued growth. As we begin to see the sun set on Moore’s Law, new techniques and technologies are needed to replace Moore’s Law and continue the performance increases we’ve come to expect.
In order to sustain the semiconductor growth we’ve come to expect, Swaminathan believes that an “Antenna to AI” platform is necessary to minimize package losses and densely integrate sensors and processing power. Image from All About Circuits’ attendance of IEEE RWW
This is not to say that semiconductors are dying; actually, quite the contrary, with Swaminathan saying “They’re projecting that the semiconductor industry will become a trillion dollar industry very soon.” In spite of this, we’ve reached an inflection point where transistors of all kinds are no longer becoming cheaper to manufacture over time.”
“Look around 2022, you see an inflection point. So, the cost of that transistor is beginning to rise. And there is a reason for it, because as you begin to scale the size of these transistors, you want a certain technology node, the capital cost becomes prohibitively high.”
In the coming years, engineers will need to work together to solve the problems present from both a microwave communication and a systems engineering perspective. Image from All About Circuits’ attendance of IEEE RWW. (Click image to enlarge)
Hope is not lost, however, as advanced packaging techniques may yield new techniques for continued integration. In addition, heterogeneous integration of RF and processing architectures together could yield a new method which Swaminathan calls “Antenna to AI”, where all the signal processing, from RF to inferencing, can be performed in more efficient chips and packages.
Plenty of Work to Be Done
Although many engineers may be worried about obsolescence as a result of new and exciting innovations such as ChatGPT and LLMs, a key fact to remember is that, although we may no longer have the same problems to solve, problems will always exist.
And whether those problems are security and efficiency concerns for RFID digital twins, or advanced semiconductor architectures for Antenna to AI platforms, engineers will always be needed to push the boundary of knowledge further and further.
This holds true in any engineering field, from microwave circuits to software design. As a result, in order to continue innovation for innovation’s sake, we should look to the future to find the hardest problems that will give the most exciting solutions.
