QuinStar’s QWH series of standard gain horn antennas cover the frequency range of 18 to 220 GHz in 10 waveguide bands. They are available with either a rectangular aperture (pyramidal shape) to connect to a rectangular waveguide or a circular aperture (conical shape) to connect to either rectangular or circular waveguide. The pyramidal horns have a nominal mid-band gain of 24dB, with 21dB typical for the conical horns. QuinStar fabricates these horns using a high-precision electroforming process. They are gold plated for use in virtually any environment.
Standard gain horns are useful for a wide variety of applications, including antenna testing, RF radiation pattern measurement, and in subsystems. These horns are often used as calibration standard or reference for antenna gain measurements. Conical horns can be used to radiate or receive either linearly or circularly polarized waves. Both shapes can be used as feed horns for lens and reflector antennas. QuinStar precisely fabricates these horns to control the aperture size and flare angle.
QuinStar offers custom horn antennas that produce customer-specific beam shapes and gain covering broad ranges. Refer to series QRR for custom feed horns.
