Compact Range Feed Horns

> Main use:

• Illumination of compact range reﬂectors

• Direct range illumination or ﬁeld probing

• Illumination of communication reﬂector antennas

> Delivered documents:

• Measured VSWR

•

Measured radiation pattern main cuts

(0°, 45°, 90° and 135°)

octave, dual linear medium gain…)

➊ TECHNICAL PERFORMANCE

• Rotationally symmetric radiation pattern

• Low cross polarization

• Stable amplitude taper with frequency

• Optimized reﬂector edge and chamber

wall illumination

➋ DESIGN

• High precision mechanical mounting

• Corrugated aperture

Which CR feed horn do you need?

Suited for Main characteristics

Low Gain Compact range with Lower amplitude

short focal length taper, lower weight,

options for full

octave bandwidth,

higher reﬂector

edge and wall

illumination, higher

cross-polarization

Medium Gain Standard focal Best overall

length ORBIT/FR performance,

reﬂectors compliant to the

compact range

catalogue speciﬁcations

High Gain Measurement applications Higher amplitude taper,

for antennas smaller lower reﬂector edge

than the speciﬁed quiet and wall illumination,

zone size that require reduced quiet zone size

high accuracy low

Mechanical drawing Medium gain feed horns with dual polarization for more efficient range utilization are available upon request. Half octave single linear feed horns The medium gain corrugated horn is the first choice for general purpose compact ranges. It offers the best overall performance in regard to amplitude taper, cross polarization performance, reflector edge illumination, chamber wall illumination, and feed leakage into the quiet zone. • Alignment pin for accurate and repeatable mounting.
