Slice-Based True-Time-Delay Receiver Arrays with Adaptive Real-Time Beam Tracking for Next-Generation Flexible Wireless Systems

Emerging applications in 6G and beyond demand highly reconfigurable, power-efficient, and wideband receiver (RX) arrays capable of maintaining robust performance under dynamic conditions. This talk presents recent advances in slice-based true-time-delay (TTD) RX architectures and adaptive real-time tracking for beam stabilization. We first discuss a four-element TTD slice-based RX array designed for the FR3 upper mid-band, which combines coarse slice-based vector modulation with fine polyphase filtering and integrated baseband TTD compensation. This hybrid approach achieves continuous 360° beam steering, mitigates beam squint, and enhances linearity and signal-to-noise ratio at the band edges. Complementing this, we explore flexible and additively printed conformal antenna arrays integrated with low-power CMOS dynamic beam stabilization (DBS) processors, which adaptively correct material imperfections and deformation-induced beam errors in real time. By unifying slice-based TTD processing with adaptive DBS control, the presented architectures enable scalable, energy-efficient arrays suitable for airborne, wearable, and dense urban wireless platforms. The talk will highlight circuit- and system-level innovations, over-the-air measurement results, and pathways toward resilient, autonomous arrays that can seamlessly adapt to wideband and dynamic environments.
