Double Ridge Guide Horn Antennas

Broadband antennas, compared to half wave dipoles, reduce test time because the technician did not have to stop the test to adjust the dipole antenna for each frequency. Most compliance standards now require the use of such antennas. The latest version of Mil-Std 461E states the used of broadband double ridge guide horn antenna as the antenna of choice for frequencies above 200 MHz.

A.H. Systems Double Ridge Guide Horns are broadband antennas that offer excellent performance over the frequency range of 170 MHz to 40 GHz. These Horn antennas are an excellent choice for both radiated immunity and emissions testing. Here are several double ridge guide horn antennas ideal for most compliance standards and/or general field measurements.

Standard Gain Horns

The Standard Gain Horn Antennas are designed specifically for utilization in emissions and immunity testing over the frequency range of 1 to 40 GHz. Each antenna is linearly polarized and has medium gain, low VSWR, and constant antenna factor. The Standard Gain Horn performance is very precise and predictable through design parameters. Comparisons of measured versus computed antenna factors and gain have been shown to be +/- .5 dB. Therefore, the antenna is considered to be a standard reference, similar to that of a resonant dipole below 1 GHz. The coax-to-waveguide adapter is the only power-limiting component on the antenna and can be removed if high fields are desired. Each Standard Gain Horn comes with a tripod mount that adapts to any tripod with ΒΌ-20 male threads. Horizontal and vertical polarization is obtained by rotating the antenna on the tripod.
Gain: 15 dB, also available in 10 dB or 20 dB gain.
