High-Frequency Spherical Near-Field Range

Our high-frequency spherical near-field test range, located in our Los Angeles office, extends the frequency range of our testing services up to 110.0 GHz and beyond. This is an ideal system for characterizing low gain antennas at mm-wave frequencies that would normally be difficult to measure. The anechoic chamber measures 2.4 m (8 ft) wide, 4.0 m (13 ft) long and 3.4 m (11 ft) high and lined with 0.3 m (12 in.) white pyramidal absorber.
