The A.H. Systems' Horn Antenna is a broadband antenna that offers excellent performance over the frequency range of 18 GHz to 26.5 GHz. High gain, low VSWR, and input handling capability up to 50 watts make this horn antenna excellent for both radiated emissions and immunity.
These millimeter wave standard gain conical and pyramidal horns feature a low cost, low VSWR, and a light weight. They’re ideal for applications involving antenna measurements and array elements, and can also be used as feeds for prime focus and Cassegrain antennas.
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 a constant antenna factor.
The double ridge guide horn antennas from A.H. Systems are designed to provide excellent performance over the 170 MHz to 40 GHz frequency range. Features include individual calibration, linear polarization, and a high power input capability.
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.
The Model ATH4G8 is a wide band, high gain, microwave horn antenna that provides a minimum gain of 11.5dB over isotropic. The Model ATH4G8 supplies the constant high intensity fields necessary for RFI/EMI field testing within and beyond the confines of a shielded room.
