Check and measurement: Rohde & Schwarz helps D-band antenna assessments for 6G automobile methods

The test solutions from Rohde & Schwarz support D-band tests in cooperation with Innovations for High Performance Microelectronics (IHP) and examine the potential for the use of radio waves in future mobile communication standards and automotive radar applications.

The D-band ranges from 110 to 170 GHz, and according to R&S, the two companies performed the industry’s first full 2D / 3D antenna characterization of transceiver modules operating in this area. According to R&S, D-band systems share some common challenges with millimeter wave systems: a large frequency range, a larger number of antenna elements, and the lack of the usual external radio frequency connections, which means that testing over radio is vital.

IHP provided four different devices tested, all based on the same D-band radar transceiver chipset but with different antenna structures. According to R&S, individual and stacked patches were included on the chip with air trenches and an antenna array on the chip. The tests showed that the stacked patches provide more bandwidth than the individual patches.

The D-band test setup consisted of a shielded antenna test chamber from Rohde & Schwarz as well as one of its vector network analyzers and its antenna measurement software. The system also uses extensions from Radiometer Physics, a part of Rohde & Schwarz, for frequency conversion on the probe to cover the D-band frequencies (both transmit and receive). R&S said no mechanical modifications or additional radio frequency cabling were necessary. Rohde said the test setup enables the measurement of the amplitude and phase-coherent response of a device under test and that its software’s options for near-field to far-field also allow it to quickly perform 3D pattern measurements and post-transformation.

Rohde used two different settings to characterize the performance of the devices, and the testing company said it was able to reduce the total test times for a DUT from 70 minutes to 12 minutes.

“Sub-terahertz frequency systems are attracting more and more attention in research and in many areas of application,” said Prof. Gerhard Kahmen, managing director of the IHP, in a statement. He praised the efficiency and precision of the test system and said the resulting measurements “are valuable in understanding the physics of antenna structures and further improving their performance. The very successful cooperation with a leading industrial partner in the field of wireless and mmWave communication shows the advantage of close interaction between research and application. “

Alexander Pabst, Vice President Systems and Projects at Rohde & Schwarz, added that the joint effort “will help researchers and key industry players test and monitor antenna systems and transceiver modules for future automotive radar applications and wireless communication standards characterize[s], that we [will]Finally, call 6G. ”
