Rohde&Schwarz and IHP first to characterize D-band frequencies in over-the-air test setup for 6G and automotive radar
(PresseBox) - Academia and key industry players have identified the D-Band, ranging from 110&&
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&
The test setup consists of the R&S&S&S&&S&UT radiating in the D-Band. Fully automated 3D-pattern measurements including post-processing can be performed in short time thanks to the R&S
IHP provided four different devices under test (DUT), based on the same D-Band radar transceiver chipset but with different antenna structures, including on-chip single and stacked patches with air trenches and an on-chip antenna array. The over-the-air characterization verified the wider bandwidth provided by the stacked patches than that by the single patch.
The performance of the various DUTs was characterized by spherical measurements, using two different setups. By increasing the angular theta step-size from 1 degree to 5 degree, the total test times for a DUT could be reduced from 70 minutes to 12 minutes. By comparing the different DUT designs based on the obtained measurement data, researchers of IHP were able to analyze the effect of the finite on-board reflector area on the radar sensor FoV (field-of-view).
Prof. Gerhard Kahmen, Managing Director of IHP, says: ?Sub-THz frequency systems are getting more and more attention in research and many fields of application. The Rohde&ructures and to further improve their performance. The very successful cooperation with an industrial partner leading in the field of wireless and mmWave communication shows the benefit of close interaction between research and application.?
Alexander Pabst, Vice President of Systems & Projects at Rohde & Schwarz says: ?We are excited to work with such an excellent partner as Innovations for High Performance Microelectronics on advancing our industry-leading test solutions for over-the-air testing. These joint efforts will help researchers and key industry players to test and characterize antenna systems and transceiver modules for future automotive radar applications and wireless communication standard, that we eventually call 6G.?
