Overview
The RF & Microwave Electronics Special Report from October 2019 highlights significant advancements and trends in the field of radio frequency (RF) and microwave technologies, particularly focusing on critical communications, antenna characterization, and emerging applications.
One of the key themes of the report is the evolution of critical communications, particularly in public safety and military sectors. Historically rooted in analog technology, these communications systems are transitioning to digital formats to enhance situational awareness and connectivity. Modern radios are now capable of supporting ad-hoc networks, which improve reliability and versatility. They can transmit high-resolution images, videos, and other data-intensive content while maintaining high-quality voice communications. This shift is facilitated by the adoption of new technologies, including digital public safety standards like APCO Project 25 (P25) and Terrestrial Trunked Radio (TETRA), as well as wireless technologies such as Long Term Evolution (LTE) and wireless local area networking (WLAN). Importantly, these systems still retain analog capabilities as a failsafe, ensuring interoperability and reliability in critical situations.
The report also discusses advancements in antenna characterization techniques, which are essential for the development and optimization of RF systems. NASA’s Glenn Research Center has developed an automated system that streamlines the characterization of small circuit antennas, whether printed on-wafer or other substrates. This innovation aims to reduce the time and cost associated with antenna testing, making it more accessible for researchers and engineers.
Another significant topic covered is the growing concern over commercial drone threats. With the rise of low-cost, wirelessly controlled drones, there is an increasing need for effective drone defense systems. The report emphasizes the importance of open-source software-defined radio (SDR) technologies in developing adaptive and responsive solutions to counteract these threats. As drone operations become more sophisticated, the ability to rapidly evolve defense mechanisms is crucial for maintaining security.
Additionally, the report touches on the role of GPS technology in future lunar missions, highlighting its potential applications in navigation and communication for space exploration. This reflects a broader trend of integrating RF and microwave technologies into various fields, including aerospace.
The SAE MOBILUS™ platform is also introduced as a valuable resource for mobility engineering, providing access to a vast collection of standards, technical papers, and other materials. The platform is designed to enhance user experience through intuitive navigation, customizable dashboards, and improved search functionalities, enabling engineers and students to focus on solving critical problems in the mobility industry.
In summary, the RF & Microwave Electronics Special Report presents a comprehensive overview of the current state and future directions of RF and microwave technologies. It highlights the transition from analog to digital communications, advancements in antenna characterization, the need for drone defense systems, and the integration of these technologies into various applications, including space exploration. The report serves as a valuable resource for professionals and researchers in the field, offering insights into the challenges and innovations shaping the future of RF and microwave electronics.
