VNA Modules Aid Antenna Testing

Jan. 9, 2013
VNA test modules help reduce the size of test systems for characterizing millimeter-wave antennas through 500 GHz.

A line of compact modules from OML for vector network analyzers (VNAs) helps characterize millimeter-wave antennas from 50 to 500 GHz. The modules are compatible with modern VNAs, including antenna test systems from Nearfield Systems. The modules, which are available in RoHS compliant versions for WR-10, WR-05, WR-03, and WR-02.2 frequency bands, enable a small variable-positioning pedestal for characterizing antennas in terms of gain, polarization, and antenna pattern for both near- and far-field operation. The waveguide flange interface used on the modules is compatible with MIL-DTL-3922/67D.
