ETS-LINDGREN’S MODEL 3186 is dual stacked log periodic dipole array antennas (LPDA), each of the two separate LPDAs comprising the dual array are 100 Ω antennas. When assembled in parallel, the results are a 50 Ω input impedance array. This array provides increased gain when compared to a single LPDA. The arrangement of the two LPDA in the arrays provides a very constant pattern across the entire frequency range.
This antenna is ideal as a receive antenna for CISPR emissions testing above 1 GHz. It is also ideal when performing the site VSWR test as per CISPR 16.
Frequency Range The antenna covers a frequency range of 1 GHz to 18 GHz, making it ideal as a receive antenna for CISPR 16 based testing above 1 GHz.
This antenna can be used with ETS-Lindgren’s Model 3183 for performing the site VSWR chamber validation method per CISPR 16.
Low VSWR The typical VSWR for the model 3186 is less than 2:1.
Low Input Power This antenna is mainly a receive antenna, with a maximum input power of 20W continuous wave and a peak power of 30W.
Constant Beamwidth and Flat Directivity The model 3186 was designed to provide a very constant illumination from 1 GHz to 18 GHz. The Beamwidth in the two principal planes is 59.8 degrees for the E-plane (the polarization plane) and 57.0 degrees for the H-plane (the orthogonal plane) while the directivity is about 10 dB across the entire frequency range.
