News | December 18, 2020 Rohde & Schwarz And IHP First To Characterize D-Band Frequencies In Over-The-Air Test Setup For 6G And Automotive Radar Academia and key industry players have identified the D-Band, ranging from 110 GHz to 170 GHz, as a candidate frequency band for beyond 5G and 6G mobile communications as well as for future automotive radar applications. Rohde & Schwarz continues its pioneering sub-THz research efforts with focus in this frequency range, reaching new milestones. In collaboration with IHP, Rohde & Schwarz has performed the industry’s first full 2D/3D antenna characterization of transceiver modules operating in the D-Band. Similar to 5G networks and devices supporting mmWave frequencies, antenna systems and RF transceiver modules for future mobile communications standards or automotive radar applications will share the same features that make their testing a challenge. Their wide frequency range, a greater number of antenna elements and the lack of conventional external RF connectors will demand testing over-the-air in a shielded environment. Wireless communications test expert Rohde & Schwarz and IHP GmbH (Innovations for High Performance Microelectronics) have transferred this test method successfully into sub-THz range: They demonstrated the first full 2D/3D over-the-air measurements of a radar module at D-Band frequencies.
