ETS-Lindgren 3116B Double-Ridged Waveguide Horn, 18 - 40 GHz

The ETS-Lindgren 3116B Double-Ridged Waveguide Horn is a the latest addition to a family of doubleridge 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. Users of this antenna benefit from uniform illumination of target surfaces and accurate gain measurement. In addition, the ETS-Lindgren 3116B exhibits high gain and low VSWR across its operational frequency band, accepting moderate power input of 20 watts.

The electrical characteristics of this antenna were designed and modeled using powerful workstations running electromagnetic simulation software. Equally important, experienced RF engineers worked with our manufacturing team to produce a practical and affordable realization of the modeling process. All production units are individually calibrated at our A2LA accredited lab.

ETS-Lindgren 3116B Features

Broadband
The 3116B horn antenna sweeps from 18 GHz to 40 GHz without stopping for band breaks, making it ideal for automated testing.

Power Input
The Model 3116B uses a Type K (2.92 mm) precision connector and accepts up to 20 watts of continuous input power. The antenna’s high gain and low VSWR over its operating frequency translates into efficient amplifier use and higher field strengths.

Uniform Gain, Low VSWR
The Model 3116B has a more uniform gain and antenna factor because of the better behavior of its radiation pattern. Since the pattern is stable over frequency, the gain and the AF also remain stable. The gain has less than 3 dB variation over the entire range. Similar antennas of this class exhibit large variations of the gain and the AF as the frequency increases.
