Minimum Scattering Probe for High Accuracy Planar NF Measurements

Technical Publications
Tuesday, November 29, 2016

Dual  polarized  wideband  probes  are convenient for accurate  and  time  efficient Planar  Near Field  (PNF)  antenna testing  [1]-[2].  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.
