“…The turnstile-junction-based OMT proposed in [10] achieved |S 11 | < −20 dB, and |S 21 | < −50 dB, for more than 50% bandwidth [11]. The turnstile OMT based probe antennas have been used in spherical near-field measurement [12], [13]. The OMT based on Bøifot junction can also provide high isolation and wide-band operation [14], [15].…”

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.

“…For the higher mm-wave frequencies, dual-port probes are challenged by reduced performances of orthomode transducers (OMT) and switches. Dual-port probes above 40 GHz based on OMTs with a turnstile junction for higher-order modes cancellation with two receiver channels have recently been reported [3], [4]. In this work, we present a first-order dual-port probe based on a high-directivity conical horn, designed and manufactured inhouse, and commercially available cables, OMT, switch, and coax-to-waveguide adapters.…”
