ETS-Lindgren's Model 3150B Dual Stacked LPDA is a dual stacked log periodic dipole array antenna (LPDA), with each of the two LPDAs being 100 antennas. When assembled in parallel, the result is a 50 input impedance array. This array provides increased gain when compared to a single LPDA. Low VSWR provides an excellent match with the amplifier, resulting in a high field generated related to input power. This antenna is suitable for situations where high fields need to be generated, such as military and in automotive EMC applications.

Key Features
  • 80 MHz to 1 GHz Frequency Range
  • Avg. 2:1 VSWR Across Range
  • Up to 5 kW Maximum Input Power
  • Suitable for Immunity Testing

Product Features

Frequency Range

The 3150B covers the 80 MHz to 1 GHz frequency range. This antenna can generate 200 V/m with less than 1 kW of input power at 1 m distance for the 100 MHz to 1 GHz range. When combined with ETS-Lindgrens 3159 or 3158 High Power Biconical Antennas, the 3150B becomes integral part of ETS-Lindgrens high severity level immunity solution.

Low VSWR

The Model 3150B's average VSWR is 2: 1 across the frequency range. This antenna comes fitted with a 7/16 DIN coaxial connector, which can handle 3 kW at 1 GHz and up to 5 kW of input power at 80 MHz.

Applications

The Model 3150B generates high fields as required in automotive EMC applications per standards such as ISO 11541-2 or MIL-STD susceptibility testing. Additionally, this antenna can be used as a receive antenna.
