ETS-Lindgren’s Model 3117 Double-ridged Waveguide is a the latest addition to a family of double ridge waveguide horns for microwave and 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 3117 exhibits high gain and low VSWR across its operational frequency band, accepting moderate power input of 300 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.
