Measurement Method Antenna Measurements in Anechoic Chambers The influence of atmospheric conditions and surrounding objects are non-ideal for accurate antenna measurements. An anechoic chamber offers a non-reflective, no-echo room for performing the antenna measurements. The anechoic chamber can simulate outer space, which is the most ideal location for antenna measurements. All gain measurements were performed in accordance with IEEE Std. 149 (IEEE Standard Procedures for Antenna Measurements). Losses of any test cables were calibrated out post-measurement. Please refer to Figure 1 as the measurement chamber diagram 1. Perform chamber calibration using reference antennas. 2. Center the EUT in the chamber using the laser alignment system. 3. Connect the antenna micro-coax cable to the mast cable. 4. Capture antenna gain pattern using the automated measurement software. 5. Export the measurement data. 6. De-embed any additional cable losses in the setup (i.e., losses of any test cables that are not present in the actual product assembly). 7. Post-process the measured data to extract the peak gain.
