ONANI TSOPANO

Planar spiral antenna ndi mlongoti womwe umagwiritsidwa ntchito potumiza ndi kulandira ma siginecha ozungulira a polarized electromagnetic mumlengalenga, okhala ndi mawonekedwe ndikugwiritsa ntchito zotsatirazi.

Khalidwe

1. Polarization mode: Planar spiral antenna ili ndi polarization mode kumanzere kapena kumanja kwa polarization mode.
2. Kufananiza kwa Impedans: Mlongoti wa Planar spiral uli ndi ntchito yabwino yofananira.
3. Kayendetsedwe ka cheza: Mlongoti uli ndi kayendetsedwe kabwino ka ma radiation, ndipo mayendedwe opitilira ma radiation amakhala mbali zonse za ndege komanso mafunde ozungulira mozungulira.
4. Makhalidwe osadalira pafupipafupi: monga ma antennas ozungulira, omwe mawonekedwe ake amatsimikiziridwa ndi ngodya ndipo samaphatikizapo kutalika kwa mzere, mawonekedwe awo samakhudzidwa ndi kusintha kwafupipafupi, ndipo ali ndi bandi yotakata kwambiri.

Kugwiritsa ntchito

1. Chidziwitso choyang'ana: Chifukwa cha kumanzere kapena kumanja kwa polarization ndikuwongolera kwabwino kwa ma radiation, mlongoti wa nyanga amatha kulandira molondola maginito amagetsi m'njira zinazake ndi ma polarizations kuti azindikire komwe chandamale ndi magwero azizindikiro.
2. Kulankhulana kwa satellite: Mlongoti wa nyanga wa RF ukhoza kugwiritsidwa ntchito ngati gwero la chakudya cha ma satellite owonetsera, kudyetsa mogwira mtima ma siginecha ofooka omwe alandilidwa ku zida zolandirira.
3. Magawo ena: Mlongoti wa nyanga ya Microwave umagwiranso ntchito mu njira zoyankhulirana zamtundu wambiri, radar yankhondo, sayansi yazachilengedwe, ndi magawo ena, monga kupewa kusokoneza pakati pa kulumikizana kwa ma ultra wideband ndi njira zolumikizirana za narrowband.

Qualwaveamapereka ma planar spiral antennas amaphimba ma frequency mpaka 40GHz. Timapereka tinyanga ta nyanga za phindu la 5dB, komanso tinyanga tambiri tomwe timapanga polarized malinga ndi zomwe makasitomala amafuna.
