1.0 Introduction
The ETS-Lindgren family of double-ridged waveguide horn antennas consists of
linearly polarized broadband antennas ranging in frequency from 100 MHz to
40GHz. These antennas were designed and built specifically for EMI
measurements and specifications compliance testing. However, they can also be
used for antenna gain, pattern measurement, surveillance, automotive and
military EMC immunity applications.
The Model 3112 Double-Ridged Waveguide
Horn Antenna is a linearly-polarized antenna
covering the frequency range of 100 MHz to 1
GHZ.
The Model 3112 is especially effective for
generating high electromagnetic fields with
relatively low power input. The antenna is also
useful for receiving low-level signals where high
gain characteristics are needed.
The Model 3106B Double-Ridged Waveguide
Horn is a linearly polarized broadband antenna
covering a frequency range of 200 MHz to 2.5
GHz. It is precision machined from aluminum,
making it lightweight and durable. Two brackets
are attached to the sides of the antenna so it can
be polarized either horizontally or vertically.
The Model 3106B has high gain and excellent
VSWR characteristics over the entire frequency
range. It is especially effective for generating
high electromagnetic fields with relatively lower
power input. The antenna is also useful for
receiving low level signals where high gain
characteristics are needed.
6 | Introduction
The Model 3119 Double Ridged Waveguide
Horn Antenna is a linearly polarized broadband
antenna covering the frequency range of 400
MHz to 6 GHz.
The Model 3119 is ideally suited for immunity
over 1 GHz, and as a reference antenna for
wireless testing. In addition, the 3119 is useful
for antenna pattern measurement as a source
antenna.
The Model 3115 Double Ridged Waveguide
Horn Antenna is a linearly polarized broadband
antenna covering the frequency range of 750
MHz to 18GHz.
The Model 3115 is ideally suited for IEC 61000-
4-3 and MIL-STD 461E immunity tests as well as
ANSI C634 and EN 55033 emissions testing. In
addition, the 3115 is useful for antenna pattern
measurement as a source antenna.
The Model 3117 Double Ridged Waveguide
Horn Antenna is a linearly polarized broadband
antenna covering the 1 GHz to 18 GHz
frequency range.
A single well defined main lobe radiation pattern
over the entire frequency range provides
excellent illumination of the Equipment Under
Test (EUT). The Model 3117 antenna is ideally
suited for IEC61000 4 3 and MIL STD 461/462
immunity tests as well as ANSI C634 and
EN 55033 emissions tests.
Introduction | 7
The ETS Lindgren Model 3116B Double Ridged
Waveguide Horn is a linearly polarized
broadband antenna covering the frequency
range 18 GHz to 40 GHz. The Model 3116B was
designed and built specifically for emissions and
susceptibility testing.
The Model 3116B is precision machined from
aluminum. A 50 ΩType K (2.92mm) female
connector is mounted on the base block of the
antenna for increased performance at high
frequencies
Models 3112 and 3117 shown with optional mounting systems.
Positioner Options
For instructions regarding mounting for each positioning system, see the user
manual for each positioner or the Mounting Instruction section of this manual.
MODEL 3112 POSITIONING SYSTEM
The Model 3112 features an
option for a fixed height pneumatic
assisted polarization positioning
system. The positioning system is
ideal when using the Model 3112
for immunity testing.
