Abstract

A dual-polarized probe enables the simultaneous sampling of two orthogonal polarizations which decreases the time for the characterization of co- and cross-polar properties of the antenna under test in transmission mode by 50%. In this work, a dual-polarized probe comprising of a square waveguide and grating polarizer based orthomode transducer is presented. The Ku-band dual-polarized probe is manufactured in-house using additive manufacturing and coated with conductive paint. The simulated and measured —10-dB impedance bandwidth is between 10.7-14.5 GHz. The peak simulated and measured coupling between the orthogonal polarizations is less than —60 dB and —40 dB, respectively.
