23 dBi Standard-Gain Horn Antennas | 18–110 GHz
23 dBi Standard-Gain Horn Antennas from 18 to 110 GHz
Use a stable, band-matched rectangular horn for antenna-range calibration, gain comparison, radiation-pattern measurements and waveguide system development.
Establish a known reference for gain and pattern measurements.
Standard-gain horns provide a practical reference antenna with predictable directional behavior. Select the horn around the exact test band, mating waveguide and flange—not just the nominal band name.
Frequency coverage
Choose the model whose published range fully covers the measurement band.
Waveguide and flange
Verify WR size, flange designation, alignment and mating hardware before ordering.
Polarization
Orient the rectangular aperture consistently with the required linear polarization.
Test geometry
Plan separation distance, alignment, mounting and reflections around the measurement setup.
Seven standard models cover K through W band.
All models below provide 23 dBi typical gain, 1.10:1 maximum VSWR, vertical linear polarization and a published temperature range of -55°C to +85°C.

Overlapping bands: adjacent horns overlap in frequency, but their WR inputs and flanges differ. Select the horn that matches the system waveguide and the measurement band.
Match frequency range, input and flange.
