The relentless demand for multi-gigabit wireless communication and high-resolution sensing
drives rapid innovation in D-band (110–170 GHz) systems. However, realizing efficient and
scalable active phased arrays at these frequencies remains challenging due to high cost,
interconnect losses, packaging parasitics, and heterogeneous integration constraints. This
talk presents a holistic, system-level approach to low-loss D-band phased array integration
that unifies circuit, antenna, and packaging co-design. Leveraging both silicon-based
(CMOS, SiGe) and III–V integrated circuits, the approach emphasizes optimized
beamformer and power amplifier architectures combined with low-cost 2D scalable, wide-
angle scanning wideband antenna arrays implemented using low-cost PCB processes.
Through electromagnetic co-optimization and advanced interconnect engineering, the
framework achieves significant reduction in loss and improvement in overall system
efficiency. Measured D-band results from prototype modules demonstrate wide-angle beam
steering and data transmission rates up to 100 Gb/s. These results confirm the feasibility of
steerable, high-capacity arrays suitable for both communication and sensing platforms.

Belgium, and since 2026, he has been a Professor at Ghent University, Ghent, Belgium.
From 2014 to 2016, he was a Senior Antenna Engineer at Remote Sensing Technologies,
Ankara, Turkey. From 2021 to 2022, he was a Visiting Scientist at the IETR Laboratory,
CNRS, Rennes, France. From 2021 to 2026, he was a Postdoctoral Fellow at Ghent
University, Ghent, Belgium. His research interests include the analysis and design of quasi-
optical systems, leaky-wave antennas, near-field focusing techniques, in-body and on-body
communication systems, active, reconfigurable, and unconventional millimeter-wave and
sub-terahertz phased arrays, as well as electromagnetic modeling and optimization of 2.5-D
and 3-D RF packaging architectures.
Dr. Kapusuz received the URSI Young Scientist Award at the 2021 URSI General Assembly.
