How is the Axial Ratio of a Polarizer Measured?

SAGE Millimeter often receives questions on measuring the axial ratio for polarizers. In this blog post, SAGE Millimeter (SAGE MM) reveals the step-by-step process of axial ratio measurement for its SAS series polarizers. A Vector Network Analyzer (VNA), Orthomode Transducer (OMT), and Mode Transition will be used to test the axial ratio. Figure 1 shows … Continue reading How is the Axial Ratio of a Polarizer Measured?
