The RFScanner is a compact bench-top scanner that characterizes antennas in your own lab environment
in real-time..

RFScanner measures the amplitude and phase of very-near-field magnetic emissions and uses these data to calculate and display far-field patterns and other parameters in real-time.


  • The RFScanner maximum radiator size is 10 cm x 16 cm. 
  • RFScanner can be used to evaluate either standalone (i.e. passive) antennas or antennas that are embedded in wireless devices (i.e. active antennas). 
  • RFScanner can be used with a few specific models of to display S11 and then calculate antenna gain and efficiency. 
  • RFScanner calculates the right and left hand circularly polarized patterns and displays axial ratio patterns. 


RFScanner provides far-field patterns, bisections, EIRP and TRP in seconds. Novel near-field
results, including amplitude, polarity and phase give insights into the root causes of antenna performance
challenges and help troubleshoot far-field radiation patterns.
