WIDEBAND HORN ANTENNAS

Wideband horn antennas are designed to deliver extremely broad frequency coverage, high efficiency, and stable directional characteristics across microwave and millimeter-wave bands. Their optimized flare geometry ensures smooth gain variation, low VSWR, and excellent linear phase response, making them ideal for EMC testing, spectrum analysis, antenna characterization, and high-dynamic-range measurement systems.

DIOON wideband horns provide consistent performance across multi-octave bandwidths, rugged mechanical construction, and precise repeatability in both laboratory and field environments.
