NSI offers broadband dual pol log periodic antennas for use as near-field measurement probes or range illuminators.
The wide bandwidth of these probes allow replacement of several standard Open Ended Waveguide (OEWG) Probes, eliminating the need to change probes frequently. The probe is delivered with typical measured probe correction data from NSI to serve as the probe model for the near-field measurement process.
These probes are ideal for spherical near-field measurements, and can be used for limited planar and cylindrical near-field measurements when the required angular span is limited to less than the probe 10 dB beam width as shown in the radiation pattern data in the data sheets.
Frequency coverage from 0.15 to 18.0 GHz (with 2 probes)
Includes NSI Pattern Calibration Files (typical)
Includes mounting flange and outline drawing
Cross polarization > 20 dB
