This quad ridged horn is a versatile antenna that can be used for a variety of purposes, including spherical near-field (SNF) testing and far-field range illumination. With its wide frequency bandwidth, it can replace several standard Open-Ended Waveguide (OEWG) probes or horns, eliminating the need to manually change range antennas. Quad ridged horns are typically smaller than equivalent OEWG probes at low frequencies, making near-field testing easier and more convenient.
Features
- Frequency range 4.0–40.0 GHz far-field use
 - Frequency range 4.0–20.0 GHz spherical near-field use
 - Wide bandwidth and low return loss
