  • Page 7: 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 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.

  • Page 8: Model 3119

    3119 ODEL The Model 3119 Double-Ridged Waveguide Horn 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.

  • Page 9: Model 3116C

    3116C ODEL The Model 3116C Double-Ridged Waveguide Horn is a linearly polarized broadband antenna covering the frequency range 10 GHz to 40 GHz. It is designed and built specifically for emissions and susceptibility testing. The Model 3116C is precision-machined from aluminum. A 50 Ω Type K (2.92 mm) female connector is mounted on the base block of the antenna for increased performance at high...
