ETS-Lindgren 3116C Overview

ETS-Lindgren 3116C

The Model 3116C Double-Ridged Waveguide Horn is 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. Users of this antenna benefit from uniform illumination of target surfaces and accurate gain measurement.

Electrical characteristics of this antenna were designed and modeled using powerful workstations running electromagnetic simulation software. 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.

Frequency Range

The Model 3116C sweeps from 10 GHz to 40 GHz without stopping for band breaks, making it ideal for automated testing.

Power Input

The Model 3116C accepts up to 20 W 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 3116C 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 4 dB variation over the entire range.

Flexible Mounting

The Model 3116C comes with a bracket that accepts either a 1/4? 20 thread screw or rear stinger mount.

Individually Calibrated

The 3116C is individually calibrated at 1m per SAE ARP 958.

Standard Configuration

  • Antenna Assembly
  • Actual Antenna Factors and a Signed Certificate of Calibration Conformance Included in Manual
  • Mounting bracket drilled to accept ETS-Lindgren or other tripod mounts with 1/4 in x 20 threads
