Minimum Scattering Probe for High Accuracy Planar NF Measurements

Dual polarized wideband probes are convenient for accurate and time efficient Planar Near Field (PNF) antenna testing

Traditional probe designs  are  often bandwidth limited and electrically large leading to high scattering [3]-[4] in PNF  measurements with  short probe-AUT distances.  In  this paper, a  full  octave bandwidth probe design  with minimum scattering characteristics is  presented, discussing design considerations,  trade-offs  and experimental results  of  the manufactured hardware.
