Iyo mbiri-polarized nyanga antenna inogona kufambisa uye kugashira yakachinjika polarized uye yakatwasuka polarized electromagnetic waves ichichengeta chinzvimbo chisina kuchinjika, kuitira kuti sisitimu nzvimbo yekutsauka kukanganisa kunokonzerwa nekuchinja antenna chinzvimbo kuti isangane nezvinodiwa zvepolarization switch inobviswa, uye kuitira kuti kurongeka kwehurongwa kuve nani. Iyo mbiri-polarized nyanga antenna ine mabhenefiti ekuwana yakakwira, kutungamira kwakanaka, yakakwira polarization yekuzviparadzanisa nevamwe, yakakwirira simba simba, nezvimwewo, uye yakadzidzwa nekushandiswa zvakanyanya. Iyo mbiri-polarized antenna inogona kutsigira mutsara polarization, elliptical polarization uye denderedzwa polarization waveforms.
Operating Mode:
| Receiving Mode |
| • Kana antenna yagamuchira mutsara wepolarized vertical waveform, yakatwasuka chete ndiyo inogona kuigamuchira, uye chiteshi chakachinjika chinobva chaiswa chega.• Kana antenna yagamuchira mutsara yakachinjika waveform, yakachinjika ndiyo chete inogona kuigamuchira, uye chiteshi chakatwasuka pacho panobva pagarwa. isolated. • Kana antenna ikagamuchira elliptical kana denderedzwa polarization waveform, yakatwasuka uye yakachinjika zviteshi zvinogashira zvakamira uye zvakachinjika zvikamu zvechiratidzo, zvichiteerana. Zvichienderana neruboshwe-ruvoko denderedzwa polarization (LHCP) kana kurudyi-kurudyi denderedzwa polarization (RHCP) yeiyo waveform, pachave ne 90-degree chikamu lagging kana kufambira mberi pakati pezviteshi. Kana iyo waveform yakanyatso denderedzwa polarized, iyo chiratidzo amplitude kubva pachiteshi ichave yakafanana. Nekushandisa yakakodzera (90 degree) hybrid coupler, iyo yakatwasuka chikamu uye yakachinjika chikamu chinogona kusanganiswa kudzoreredza denderedzwa kana elliptical waveform. |
| Transmitting Mode |
| • Kana antenna ichidyiswa nechiteshi chakatwasuka, inotumira mutsara wakatwasuka polarization waveform. • Kana antenna ichidyiswa nechiteshi chehorizontal, inotumira iyo yakatwasuka mutsara polarization waveform. • Kana antenna ichipihwa kune yakatwasuka uye yakachinjika zviteshi nemusiyano we90-degree phase, akaenzana amplitude masaini, iyo LHCP kana RHCP waveform inofambiswa zvinoenderana nechikamu chekusarira kana kufambira mberi pakati pezvikwangwani zviviri. Kana iyo masaini amplitudes emadoko maviri asina kuenzana, iyo elliptical polarization waveform inofambiswa. |
| Transceiving Mode |
| • Kana iyo antenna inoshandiswa mukutumira uye kugamuchira maitiro, nekuda kwekuparadzaniswa pakati pezvikepe zvakamira uye zvakadzikama, inogona kutumira uye kugamuchira panguva imwe chete. |
RF MISOinopa maviri akatevedzana maviri-polarized antennas, imwe yakavakirwa pane yequad-ridge chimiro uye imwe yakavakirwa paWaveguide Ortho-Mode Transducer (WOMT). Izvo zvinoratidzwa muMufananidzo 1 uye Mufananidzo 2 maererano.

Mufananidzo 2 Dual-polarized nyanga antenna yakavakirwa paWOMT
Kufanana uye kusiyana pakati pemaantenna maviri kunoratidzwa muTebhu 1. Kazhinji kutaura, antenna inobva pane quad-ridge structure inogona kuvhara bandwidth yakawanda yekushanda, kazhinji yakawanda kupfuura octave band, yakadai se1-20GHz uye 5-50GHz. Nehunyanzvi hwekugadzira dhizaini uye yakakwirira-chaiyo nzira dzekugadzirisa,RF MISO's Ultra-wideband dual-polarized antenna inogona kushanda kune yakakwirira frequency yemamita masaisai. Iyo inoshanda bandwidth yeWOMT-yakavakirwa antenna inogumira neiyo inoshanda bandwidth yewaveguide, asi kuwana kwayo, danda upamhi, mativi lobes uye kuyambuka polarization / chiteshi-kune-chiteshi kuparadzaniswa kunogona kuve nani. Parizvino pamusika, akawanda maviri-polarized antennas akavakirwa paWOMT ane 20% chete yeanoshanda bandwidth uye haakwanise kuvhara yakajairwa waveguide frequency band. Iyo WOMT-yakavakirwa mbiri-polarized antenna yakagadzirwa naRF MISOinogona kuvhara iyo yakazara waveguide frequency bhendi, kana pamusoro peiyo octave bhendi. Kune akawanda mamodheru ekusarudza kubva.
