Improved Antenna Pattern Accuracy of a Benchtop Real-Time Measurement Solution with Upcoming Extensions to X-Band, Ku-Band and mmWave

EMSCAN’s RFxpert is a benchtop very-near-field test system that is able to accurately measure radiated power and efficiency for antennas. This system allows designers to easily and quickly check antenna and wireless device performance without always needing to resort to a chamber. Advances by EMSCAN are pushing the frequency range of this system up to 20 GHz and soon into the mmWave region. At these frequencies a completely new family of solver based on method of moments will improve the resulting pattern accuracy including phase accuracy. This presentation will discuss the performance of the 20 GHz system and show how the new solver is already being applied to sub 6GHz measurements to accurately evaluate antenna performance in seconds.
