Elva’s SGPH series of standard gain horn antennas cover the frequency range of 18 to 220 GHz in ten waveguide bands. They can be issued with rectangular or circular waveguide. Lens technology significantly allows decreasing mechanical sizes of horns and correcting beam for the best performance. These horns are ideal solution for measurement gain of other antennas, short range radars and radiometers.
Elva’s SLHA series of standard gain horn lens antennas cover the frequency range of 18 to 220 GHz in ten waveguide bands. They can be issued with rectangular or circular waveguide. Lens technology significantly allows decreasing mechanical sizes of horns and correcting beam for the best performance. These horns are ideal solution for measurement gain of other antennas, short range radars and radiometers.
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.
These Octave range EMC horn antennas offer an unrivalled facility for EMI/RFI testing, evaluation and electronic surveillance. The band of 0.5 GHz to 18 GHz can be covered with only 2 to 4 EMC antennas.
The Broadband Horn antennas BBHA 9120 offer a very low SWR in their nominal frequency range and a very broad bandwidth. The gain increases with frequency up to approx. 18 dBi, depending on the horn's size and shape. The increasing gain with frequency helps to compensate cable losses. The BBHA 9120 series is suitable for both, transmission and receiving applications.
RPG has been designing and manufacturing electroformed corrugated horns for over 20 years. Quality control of the process to space-qualification standards ensures no fluid or air-inclusions, which is damaging in a vacuum environment. The cut-away inspection of a corrugated horn shown above. Corrugated feed horns have been made higher than 1.5THz.
RPG standard pyramidal gain horns are used to measure gain of other antennas. These horns are offered with 15, 20 and 25 dB gain over a frequency of50 to 1700 GHz. The standard gain horns are ideally suited for reference sources in dual channel antenna test receivers, and can be used as pickup horns for radiation monitoring.
The Model 3116B Double-Ridged Waveguide Horn is a the latest addition to a family of double-ridge guide horns for EMC measurement from ETS-Lindgren. This model corrects the lower gain at the upper end of the frequency range, commonly found in ridged waveguide antennas.
Cobham Sensor Systems builds two distinct types of horn antennas: Standard Gain or Calibration Horns, and Broadband Horns. Standard Gain Horns are optimized for low VSWR and provide equal E- and H- plane 3dB beamwidths. These horns are most often used as gain standards for antenna testing. VSWR data are typically supplied with each horn. Calibration data is also available upon request.
The TDK RF Solutions HRN-0118 Horn Antenna is designed specifically for radiated emissions and immunity measurements in EMC test environments. The HRN-0118 provides optimal performance over the frequency range of 1 to 18 GHz.
