In the world of wireless technology, few people see the invisible signals that connect our devices, satellites, and sensors. Ana Inês Inácio, a research scientist at the Netherlands Organization for Applied Scientific Research (TNO), is one of them. She designs integrated circuits that form the backbone of next-generation RF sensor systems—critical for advancing radar and communication technologies. But Inácio's impact goes beyond her technical work. As an IEEE Senior Member and winner of the IEEE–Eta Kappa Nu Outstanding Young Professional Award, she also dedicates herself to building professional communities. Here are seven things you need to know about the scientist shaping the future of wireless.

1. Pioneering RF Circuit Design for Next-Gen Sensors

Ana Inês Inácio’s core expertise lies in designing integrated circuits for radio-frequency (RF) systems. At TNO in The Hague, she works with signals most people never notice: radio waves moving between satellites, sensors, and future wireless networks. These invisible signals are essential for advanced radar technologies. Inácio’s circuits enable sensor systems to detect and process RF signals with higher precision, lower power consumption, and greater reliability. Her work is foundational for applications ranging from autonomous vehicles to environmental monitoring. By pushing the boundaries of what RF circuits can achieve, she ensures that next-generation wireless networks are faster, smarter, and more efficient.

2. Winning the IEEE–Eta Kappa Nu Outstanding Young Professional Award

In 2023, Inácio received the prestigious IEEE–Eta Kappa Nu Outstanding Young Professional Award for her “leadership in IEEE Young Professionals, fostering innovation and inclusivity, and pioneering advancements in RF sensor systems.” This recognition from IEEE’s honor society celebrates her dual impact: technical excellence and community engagement. The award highlights how she bridges the gap between cutting-edge research and real-world applications, all while mentoring the next generation of engineers. For Inácio, the award is not just an honor—it’s a testament to her belief that engineering thrives when people connect, share ideas, and grow together.

3. From a Rural Village to Global Recognition

Inácio’s journey began in Vales do Rio, a small village near Covilhã in central Portugal, known for farming and textiles. Her grandfather, a self-taught machinery repairman, became her first engineering teacher. Through correspondence courses, he learned electrical systems and would explain to young Ana why a broken appliance failed and how to fix it. This early exposure sparked her curiosity. Her mother worked as a tailor, her father switched from factory work to culinary school, and curiosity ran in the family. By high school, Inácio was equally drawn to math, physics, biology, and geology. Encouragement from teachers and an uncle who was an engineer steered her toward electronics engineering—a path that would lead her to international acclaim.

4. Finding Her Path Through an Exchange Program

In 2008, Inácio enrolled in an integrated master’s program in electrical and telecommunications engineering at the Universidade de Aveiro (UAveiro) in Portugal. A pivotal moment came in 2012 when she moved to the Netherlands for a six-month exchange at Eindhoven University of Technology (TU/e). That experience changed her trajectory. It opened her eyes to new research opportunities and exposed her to a vibrant international engineering community. After completing her degree, she returned to the Netherlands to pursue a career at TNO. The exchange program not only shaped her technical skills but also ignited her passion for global collaboration—a theme that runs throughout her career.

5. Building Professional Communities Alongside Circuits

Inácio’s career follows two parallel paths: advancing RF circuit design and helping engineers worldwide build professional communities. She is an active leader in IEEE Young Professionals, where she organizes events, mentors students, and promotes inclusivity. “I’ve always liked building things,” she says. “Sometimes that means circuits; sometimes it means helping people connect and grow together.” This philosophy has led her to foster innovation and collaboration across borders. She believes that technical excellence alone isn’t enough—engineers need to share knowledge, support each other, and create environments where diverse perspectives can thrive.

6. The Power of Self-Taught Ingenuity in Her Family

Inácio’s grandfather never held an engineering degree, but he taught himself electrical systems through correspondence courses. He would repair household appliances and explain the principles to his granddaughter. This DIY mentality influenced Inácio’s approach to problem-solving. She learned that you don’t need a formal title to be an innovator—you just need curiosity and persistence. Her mother, a tailor, and her father, a chef, also instilled a work ethic and a love for lifelong learning. Today, Inácio carries that spirit into her research, where she often tackles challenges by combining fundamental physics with creative circuit design. It’s a reminder that the best engineers are often those who never stop asking “why?”

7. Shaping the Future of Wireless, One Signal at a Time

Beyond her daily work at TNO, Inácio is driven by a larger vision: making wireless technology more sustainable, accessible, and impactful. Her RF sensor systems are critical for radar, autonomous navigation, and the Internet of Things. But she also sees the human side of technology—how better connectivity can improve lives, from remote healthcare to emergency response. As an IEEE Senior Member, she mentors young professionals and advocates for diversity in STEM. Inácio believes that the future of wireless isn’t just about faster data; it’s about building networks that bring people together. Her career exemplifies how technical innovation and community leadership can go hand in hand to create a smarter, more connected world.

Ana Inês Inácio is more than a scientist—she is a bridge between invisible signals and visible change. From her grandfather’s kitchen table in Portugal to the labs of TNO in the Netherlands, she has shown that engineering is both a technical discipline and a human endeavor. Her work on RF circuits will power the wireless systems of tomorrow, while her commitment to community building ensures that those systems are developed by diverse, inclusive teams. Inácio’s story is a testament to the power of curiosity, mentorship, and the belief that we can all shape the future—one signal, one connection, at a time.
