YIC RFScanner Overview

Antenna Pattern Measurement and Diagnostic Tool on your Lab-bench

YIC Technologies RFScanner

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

The RFScanner measures the amplitude and phase of near-field magnetic emissions and uses these data provides far-field patterns, bisections, EIRP and TRP and other parameters 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 in real-time.

  • Frequency Range of 300 MHz to 6.0 GHz
  • Far-Field Patterns and Bisections including EIRP / TRP / PRD, Circular and linear polarization and axial ratio patterns
  • Near-Field Insights such as Amplitude and Phase distribution available in seconds
  • Gain, Efficiency and S11 chart with Supported VNAs
  • "Real-time" real-fast
  • Can be used to evaluate either standalone (i.e. passive) antennas or antennas that are embedded in wireless devices (i.e. active antennas).
  • Simple set up and Easy to use

The RFScanner can also integrate with a network analyzer or a Spectrum Analyzer with a Tracking generator to measure gain, efficiency and S11 of an antenna across a frequency range. Users can execute real-time analysis of their embedded antenna designs and test multiple design iterations, on the lab bench, in seconds at each stage of the design process.

The RFScanner gives wireless engineers the freedom to do rapid prototyping and explore new designs, new materials and new forms. Wireless engineers and designers can test multiple design variations and optimize complex embedded antenna designs at their lab bench in seconds without wasting time waiting in congested anechoic chamber lines. They can optimize positioning and effects from layout, monitor changes from packaging or layout changes or verify performance of final product in real-time and then go to the chambers for final certification requirements with their mind at ease, knowing that their design will achieve a first-time pass.

With the Circular Polarization (CP) option, the RFS calculates the right and left hand circularly polarized patterns and displays axial ratio patterns. RFS can be integrated into virtually any automated test bed and production line by using DLL programming.

As a golden sample comparison tool with real time results, the RFS is also ideal for sample lot testing and product verification for wireless service providers or for manufacturing support. The RFS allows design teams to reduce testing time by at least one order of magnitude, provides an easy-to-use, cost effective, and proven tabletop solution
