Technical Education Webinar Series

Title: Making Long-distance Antenna Measurements Simple and Easy

Date: December 6, 2022

Time: 8am PT / 11am ET

Sponsored by: Anritsu Company

Presented by: Michael Yang, Senior Technologist, Anritsu Company

Abstract:

Outdoor antenna test ranges are used in similar ways to large RF test chambers but may be used to test larger/higher power antennas over longer distances. This includes far-field testing for lower frequencies, as the distance from the antenna to the far-field is a function of wavelength. The distances from the antenna to the test port and the desired dynamic range make these measurements difficult with traditional test and measurement methods. Moreover, for antenna null testing and beam steering testing, the measurement antenna may require repositioning that may impact the uncertainty of the measurements.

This webinar will review traditional long cable insertion loss test solutions and the limitations and drawbacks of these methods. It will also discuss an innovative distributed modular VNA architecture that can simplify the setup and measurement for both measured dynamic range and group delay.
