What if the antenna could be as integrated as the transistor? As wireless systems push the boundaries of miniaturization, speed, and integration, the concept of on-chip antennas is rapidly transforming from a niche curiosity to a cornerstone of next-generation RF, microwave, and millimeter-wave technologies.

 This talk explores the intriguing world of on-chip antennas—where electromagnetic radiation meets silicon real estate. We delve into the fundamental challenges of antenna miniaturization, substrate losses, and impedance matching, and examine how innovative design strategies are overcoming these barriers. From CMOS-compatible layouts to metamaterial-inspired structures, on-chip antennas are enabling seamless integration of wireless functionality directly into ICs.

 Why does this matter? Because the future of high-speed communication, radar sensing, and chip-to-chip wireless interconnects depends on it. Whether it's for 5G/6G transceivers, biomedical implants, or terahertz imaging systems, on-chip antennas are poised to unlock new possibilities across the RF, microwave, and millimeter-wave spectrum.

 Join me as we walk through the milestones of on-chip antenna development and ask: Can antennas truly become native to silicon? And if so, what new frontiers will that open?

This talk will cover:

·        Fundamentals of on‑chip antenna physics

·        Key challenges (efficiency, isolation, substrate effects, EM compatibility)

·        Design trade‑offs in advanced CMOS nodes

·        Co‑design strategies with RF front‑end circuits

·        Emerging applications in 5G/6G, IoT, and miniaturized sensing systems
