MultiPort Antenna Data Acquisition (MPADA) is a tool for automating S parameter data collections from MIMO antennas. The tool enables automatic testing and control to a set of RF switches and Vector Network Analyzer (VNA).

Features

• Web based VNA control (remote access possible)
• Single sweep across single/multiple antenna elements
• Time series S-parameter sweep concurrent with other modalities
• Sequential S-parameter sweep concurrent with other modalities

Installation

• (Recommended) Create python environment
• Install required packages $ pip install -r requirements.txt
  • if manual install is desired, please refer Required Packages
• Verify VISA driver as required by PyVISA
• Start MPADA!
  • $ python app.py
  • • navigate to http://127.0.0.1:7860
• Happy sweeping!

Hardware Requirements

• Vector Network Analyzer
  • tested on Keysight PNA series but works on most VNAs support standard SCPI
• RF switch
  • e.g., HMC321A
• Microcontroller
  • e.g., FT232H, C232HD, RP2040 in u2if mode
• Antenna
  • aka your design!
• Cable, adapter, etc.

Roadmap

• add support to import/export antenna configurations
• add support to dynamic antenna port configuration

Required Packages

• python
• gradio
• python-dotenv
• matplotlib
• numpy
• pandas
• pyvisa
• pyftdi
