As wireless systems push the boundaries of miniaturization and speed, on-chip antennas are rapidly becoming a cornerstone of next-generation RF, microwave, and millimeter-wave technologies. In this online session, Dr. Arup Ray will explore the critical integration of electromagnetic radiating elements directly into silicon architectures. The talk will address fundamental design challenges—such as substrate losses and impedance matching—and highlight innovative solutions like CMOS-compatible layouts and metamaterial structures. Attendees will gain technical insights into how on-chip antennas are driving advancements in 5G/6G communications, biomedical implants, radar sensing, and wireless chip-to-chip interconnects.
