  • Page 5: Introduction

    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.
  • Page 6 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.

  • Page 7: Positioner Options

    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.
