Measurement and Diagnostics of Millimeter Waves 5G Enabled Devices

摘要

5G communication is the new evolution of wireless services, whose aim is the creation of a network with much larger performances than previous cellular generations. 5G will connect new industries and empower a multitude of new user applications. Since 5G operates at millimeter wave frequencies in the range 10-300 GHz, the design, developments and testing of antennas, embedded in 5G wireless devices, have been consequently influenced. For smart testing and diagnostics of 5G enabled devices, fast and accurate antenna measurement systems are needed to satisfy the short cycles in development, testing and production to which today's antenna engineer are working. Multi-probe antenna measurement systems are based on a consolidated technology currently employed from 70MHz up to 18GHz. This paper, describes the recent advances in multi-probe technology as implemented in StarLab 50GHz, ideal for testing 5G application antennas in the 18-50GHz frequency range. Diagnostics and troubleshooting of antennas integrated in 5G enabled devices is enabled by post-processing using equivalent currents. To illustrate the testing capabilities, measured examples, including diagnostics on a 5G Millimeter-Wave Mobile Terminal are presented. The possibility to determine power density in the near vicinity of 5G devices by equivalent currents processing to verify compliance with safety normative is also presented.
