RFlect - Antenna Plot Tool

Version: 3.0.0

RFlect is a comprehensive antenna plotting tool, currently designed specifically for visualizing and analyzing antenna measurements from the Howland Company 3100 Antenna Chamber and WTL Test Lab outputs. Additionally, it offers support for .csv VNA files from Copper Mountain RVNA and S2VNA software of S11/VSWR/Group Delay(S21(s)) measurements, making it a versatile choice for a wide range of antenna data processing needs. Through its user-friendly graphical interface, RFlect provides an intuitive way to handle various antenna metrics and visualize results.

Installation

1. Run the provided installer from the latest release (RFlect_vX.X.X.exe)
2. Follow the on-screen instructions to complete the installation.

How to Use

Select Scan Type:

• Choose from Active, Passive, or .csv (VNA/S-Parameters) scan.

  

Adjust Settings (if needed):

• Click the Settings button to open the settings window.
• Depending on your scan type selection, adjust the relevant settings.
  • For VNA/S11 LogMAG scans, you can set limit lines.
  • Select Group Delay & SFF(future implementation) for Group Delay Measurements, Peak to Peak Delay Difference, etc from 2-Port S2VNA .csv files
  • For Passive scans, select between G&D or HPOL/VPOL.
  • Datasheet Plots Check Option will additionally plot Peak Phi & Theta Gain vs Frequency with Total Gain vs Freq. Also plots Elevation/Azimuth 2D cuts for 3-planes.
  • For Active scans, future implementation

Import Data:

• Click the Import File(s) button.
• Follow the on-screen prompts to select and import your data files.

View Results:

• If you've selected a VPOL/HPOL Passive scan, or Active Scan, you can click View Results to visualize the data.
• For other scan types, results will be displayed after data import.
