XHUMANA MANJE

I-planar spiral antenna wuthi olusetshenziselwa ukudlulisa nokwamukela amasignali ajikelezayo e-polarized electromagnetic emkhathini, enezici nezindlela ezilandelayo.

Isici

1. Imodi ye-polarization: I-Planar spiral antenna inemodi ye-polarization yesandla sokunxele noma imodi ye-polarization yesandla sokudla.
2. Ukumatanisa kokuphazamiseka: I-Planar spiral antenna inokusebenza okuhle kokumadanisa kwe-impedance.
3. Isiqondiso sokukhishwa kwemisebe: I-antenna inokusebenza okuhle kokuqondiswa kwe-radiation, lapho isiqondiso semisebe esiphezulu sisendleleni evamile kuzo zombili izinhlangothi zendiza futhi ikhipha amaza ayindilinga ayindilinga.
4. Izici ezingancikile kumafrikhwensi: njengama-equiangular spiral antennas, umumo wazo unqunywa i-engeli futhi akubandakanyi ubude bomugqa, izici zazo azithintwa izinguquko zefrikhwensi, futhi zinebhendi yefrikhwensi ebanzi kakhulu.

Isicelo

1. Ukuma kolwazi: Ngenxa yemodi ye-polarization yesandla sobunxele noma yesandla sokudla kanye nokusebenza kahle kokuqondisa emisebeni, i-antenna yophondo ingathola ngokunembile amasignali kazibuthe kagesi emikhombandlela ethile kanye ne-polarizations yokutholwa kabusha kokuma okuhlosiwe kanye nemithombo yesignali.
2. Ukuxhumana ngesathelayithi: I-antenna ye-RF horn ingasetshenziswa njengomthombo wokuphakelayo wamasathelayithi abonisayo, ngokuphakela kahle amasiginali wesathelayithi abuthaka atholiwe emishinini eyamukelayo.
3. Eminye imikhakha: I-antenna ye-Microwave horn iphinde ibe nezinhlelo zokusebenza ezinhlelweni zokuxhumana ze-ultra wideband, i-radar yezempi, i-biotechnology, neminye imikhakha, njengokugwema ukuphazamiseka phakathi kokuxhumana kwe-ultra wideband nezinhlelo zokuxhumana ze-narrowband.

Qualwaveihlinzeka ngama-antenna ajikelezayo ahlanganisa imvamisa yebanga elifika ku-40GHz. Sinikeza izimpondo ezijwayelekile zokuzuza kwenzuzo engu-5dB, kanye nezimpondo ezimbili ezenziwe ngezifiso ngokwezidingo zamakhasimende.
