Antena yenyanga ine polarized mbiri inogona kutumira nekugamuchira mafungu emagetsi ane polarized uye vertical polarized uku ichichengetedza mamiriro enzvimbo isina kuchinja, kuitira kuti kukanganisa kwekutsauka kwenzvimbo yesystem kunokonzerwa nekuchinja nzvimbo yeantenna kuitira kuti isangane nezvinodiwa zvekuchinja kwepolarization, uye kuitira kuti kunyatsorongeka kwesystem kuve nani. Antena yenyanga ine polarized mbiri ine mabhenefiti ekuwedzera kukuru, kutungamira kwakanaka, kupatsanurwa kwepamusoro kwepolarization, kugona kwesimba rakawanda, nezvimwewo, uye yakadzidzwa zvakanyanya uye yakashandiswa zvakanyanya. Antena ine polarized mbiri inogona kutsigira linear polarization, elliptical polarization uye circular polarization waveforms.
Maitiro Ekushanda:
| Nzira Yokugamuchira |
| • Kana antenna ikagamuchira waveform yakatsetseka yakatsetseka, chiteshi chakatsetseka chete ndicho chinogona kuigamuchira, uye chiteshi chakatsetseka chinobviswa. • Kana antenna ikagamuchira waveform yakatsetseka yakatsetseka, chiteshi chakatsetseka chete ndicho chinogona kuigamuchira, uye chiteshi chakatsetseka chinobviswa. • Kana antenna ikagamuchira waveform yedenderedzwa kana kuti yakatenderera, maports akatwasuka neakatambanudzwa anogamuchira zvikamu zvakatwasuka neakatambanudzwa zvechiratidzo, zvichiteerana. Zvichienderana nedenderedzwa rekuruboshwe (LHCP) kana denderedzwa rekuruboshwe (RHCP) rewaveform, pachava nekunonoka kana kufambira mberi kwemadhigirii makumi mapfumbamwe kana kupfuura pakati pemaports. Kana waveform yakatenderera zvakakwana, amplitude yechiratidzo kubva pachiteshi ichave yakafanana. Nekushandisa coupler chaiyo (90 degrees) yehybrid, chikamu chakatwasuka nechikamu chakatwasuka zvinogona kusanganiswa kuti zvidzore waveform yakatenderera kana yakatenderera. |
| Nzira yekutumira |
| • Kana antenna ikashandiswa nechiteshi chakamira, inotumira waveform ye polarization yemutsetse wakamira. • Kana antenna ikadyiswa nechiteshi chakatarwa, inotumira waveform ye polarization yemutsara wakatarwa. • Kana antenna ikaendeswa kumaports akamira uye akatwasuka ne90-degree phase difference, equal amplitude signals, LHCP kana RHCP waveform inotumirwa zvichienderana nephase lagging kana kufambira mberi pakati pesignals mbiri. Kana amplitude yesignal yemaports maviri isina kuenzana, elliptical polarization waveform inotumirwa. |
| Nzira yekutumira |
| • Kana antenna ikashandiswa mukutumira nekugamuchira, nekuda kwekuparadzaniswa pakati pemaports akamira neakatwasuka, inogona kutumira nekugamuchira panguva imwe chete. |
RF MISOine maantenna maviri akatevedzana ane polarized maviri, rimwe rakavakirwa pachimiro che quad-ridge uye rimwe rakavakirwa paWaveguide Ortho-Mode Transducer (WOMT). Anoratidzwa muMufananidzo 1 neMufananidzo 2 zvichiteerana.
Mufananidzo 1 Antena yenyanga ine mativi mana ine mativi maviri

Kufanana uye musiyano uripo pakati pemaantenna maviri aya zvinoratidzwa muTafura 1. Kazhinji, antenna yakavakirwa pachimiro chequad-ridge inogona kufukidza bandwidth yakakura yekushanda, kazhinji kupfuura octave band, senge 1-20GHz uye 5-50GHz. Nehunyanzvi hwekugadzira hwakanaka uye nzira dzekugadzirisa dzakanyatsojeka,RF MISOAntenna ine ultra-wideband dual-polarized inogona kushanda kusvika kuma frequency akakwira ema millimeter waves. Bandwidth yekushanda yema antennas eWOMT inogumira nekuda kwe bandwidth yekushanda ye waveguide, asi gain yayo, beam width, side lobes uye cross polarization/port-to-port isolation zvinogona kuva nani. Parizvino pamusika, ma antennas akawanda ane dual-polarized akavakirwa paWOMT ane 20% chete ye bandwidth yekushanda uye haagone kufukidza standard waveguide frequency band. Antenna ine dual-polarized yeWOMT yakagadzirwa naRF MISOinogona kufukidza bhendi remafungu ese ewaveguide, kana pamusoro pebhendi reoctave. Kune mamodheru akawanda ekusarudza kubva.
