Kyocera and Rohde & Schwarz demonstrate OTA characterization of mmWave PAAM at CES 2026

Kyocera and Rohde & Schwarz demonstrate OTA characterization of mmWave PAAM at CES 2026 Kyoceras innovative mmWave phased array antenna module (PAAM) generates multiple simultaneous beams in different directions and frequencies, enabling a wide range of sensing and communications applications. To optimize beam steering and directivity of their product, Kyocera utilizes CATR-based multi-reflector over-the-air (OTA) testing technology from Rohde & Schwarz.

Kyocera and Rohde & Schwarz will showcase the characterization of Kyocera's novel phased array antenna module (PAAM) at CES 2026 in Las Vegas, NV. The demonstration at the Kyocera booth (6501, LVCC, West Hall) will feature the R&S ATS1800M 5G NR multi-directional mmWave test chamber from Rohde & Schwarz, known for its exceptionally small footprint and over-the-air (OTA) testing capabilities.

Kyocera has developed a novel phased array antenna module (PAAM) for a variety of sensing and communications applications. Featuring 384 dual-polarization elements, the PAAM can create up to eight simultaneous beams with varying directions and frequencies. This design incorporates 6G ISAC (Integrated Sensing and Communication) technology that combines wireless communication and sensing into a single framework. It allows networks to simultaneously deliver data and sense their environment, unlocking applications such as next-generation autonomous driving, environmental sensing, and industrial automation-all with greater efficiency and performance.

Ensuring all antenna elements work cohesively to form an RF beam with the desired characteristics is critical. Rohde & Schwarz offers a patented over-the-air (OTA) testing approach within a fully shielded environment, allowing engineers to verify beam patterns and minimize sidelobes.

The R&S ATS1800M is a unique solution featuring four feed antennas and CATR reflectors, each providing a 30 cm quiet zone (QZ). At CES 2026, the Kyocera PAAM device under test (DUT) will be positioned on a rugged 3D positioner at the center of the four overlapping QZs. This configuration allows Kyocera's engineers to conduct a variety of tests, including the simultaneous reception of RF beams from multiple directions. The patented vertical CATR design minimizes the system's lab footprint compared to other OTA solutions.

The complete test setup incorporates multiple instruments from Rohde & Schwarz, including signal generators and analyzers alongside the mmWave test chamber, providing a fully integrated testing environment. The device under test receives four independent signals via the chamber's reflectors, simulating complex reception scenarios, and the resulting signal quality is measured and analyzed. This comprehensive system enables thorough evaluation of the phased array antenna module's performance in realistic conditions.

Visitors to CES 2026 can experience this milestone demonstration live at the Kyocera booth (6501) in the West Hall of the Las Vegas Convention Center, from January 6 to 9, 2026.
