The iEMSL houses a fully functional Anechoic Chamber and associated equipment to enable antenna characterization measurements from 400 MHz to 140 GHz. The chamber interior measures 24 ft, 10 ft and 6.5 ft in length, width and height. It features a quiet zone with better than 20 dB attenuation using an automated measurement system for RF, microwave and millimeter-wave frequencies. The chamber is located in the Wisenbaker Engineering Building (WEB) room 160.
This facility is currently used to characterize the input match as well as 2D and 3D radiation patterns of the antennas from 400 MHz to 40 GHz. The maximum antenna (or system) size should be 24 x 24 inches with a depth of 24 inches or less. Usage of the chamber is conducted through the iEMSL’s Measurement Services program.
