Model 3117

The Model 3117 Double Ridged

Waveguide

is a the latest addition

to a family of double ridge

waveguides 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 Model 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.

FEATURES

Single Lobe Radiation Pattern

The Model 3117 maintains a single

main lobe pattern in the direction

of the horn axis over its frequency

range. This characteristic is

essential for even distribution of

electromagnetic energy on a target

surface, and accurate measurement

of gain and vector information.

The Model 3117’s unique design

suppresses the propagation of

high order modes. The result is

an antenna with a well-defined

single lobe radiation pattern that

outperforms other antennas in its

class.

Ultra Broadband

The Model 3117 sweeps from

1 GHz to 18 GHz without stopping

for band breaks, making it ideal
