Introduction - ETS-Lindgren 3112 User Manual

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
40 GHz. These antennas were designed and built specifically from EMI
measurements and specifications compliance testing. However, they can also be
used for antenna gain, pattern measurement, surveillance, automotive and
military EMC immunity applications.
M 3112
ODEL
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.
M 3106B
ODEL
The Model 3106B Double-Ridged Waveguide
Horn Antenna 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 horizontal or vertically.
The Model 3106B has high gain and excellent
VSWR characteristics over the entire
frequency range (see Appendix B). It is
especially effective for generating high
electromagnetic field with relatively low power
input. The antenna is also useful for receiving
low level signals where high gain
characteristics are needed
