Turnstile junction Ortho-mode Transducer for W-band radar seeker

Computer‐aided development and experimental investigation of a double‐ridged orthomode transducer for modern satellite and space communication systems

“…A wider operating frequency band is provided only by the counterpart antenna from Reference 106, but its matching and isolation are much worse and unacceptable by many modern radio engineering appliances. The values of rectangular waveguide ports isolation, which are obtained in proposed antenna and counterparts from References 104,105 are comparable to each other. Moreover, in designed antenna system the reflection coefficient was improved by 7–15 dB.…”

“…In order to demonstrate advantages in performance of proposed antenna system based on developed doubleridged OMT let us compare it with several existent counterparts based on other types of waveguide polarization duplexers. [104][105][106][107] Achieved characteristics of bandwidth, matching and isolation are summarized in Table 1.…”

“…Table 1 clearly demonstrates benefits in performance, which are provided by the developed dual‐polarization antenna system based on double‐ridged OMT. Designed antenna allows to operate in wider frequency bands compared to the counterparts reported in References 103–105. A wider operating frequency band is provided only by the counterpart antenna from Reference 106, but its matching and isolation are much worse and unacceptable by many modern radio engineering appliances.…”
