Izinto ezithinta uthi

1. Ngokwemvelo yomsebenzi, ingahlukaniswa ibe i-antenna yokudlulisa nokwamukela i-antenna.

2. Ngokusho kwenhloso, ingahlukaniswa ngama-antenna okuxhumana, ama-antenna okusakaza, ama-TV, ama-radar antenna, njll.

3. Ngokobude begagasi obusebenzayo, ingahlukaniswa ibe i-antenna yamagagasi amade, i-antenna yegagasi elide, i-medium wave antenna, i-wave wave antenna, i-ultra short wave antenna, i-microwave antenna, njll.

4. Ngokwesakhiwo kanye nesimiso sokusebenza, ingahlukaniswa ibe izimpondo zomugqa kanye nezimpondo ezingaphezulu.Amapharamitha wesici achaza uthi iphethini, i-directivity coefficient, inzuzo, i-impedance yokufaka, ukusebenza kahle kwemisebe, i-polarization kanye nemvamisa.

Ama-antenna angahlukaniswa abe izinhlobo ezimbili ngokuya ngenani lobukhulu: izimpondo ezinohlangothi olulodwa kanye nezimpondo ezimbili.Ama-antenna anohlangothi olulodwa akhiwa izintambo eziningi.Lezi zintambo kungaba imigqa eqondile esetshenziswa kumakhalekhukhwini, noma ezinye izimo ezihlakaniphile, njengezintambo.Izindlebe zikagwaja ezindala ngaphambilini bezisetshenziswa kumasethi we-TV.I-Monopole kanye nezinti ezinezigaba ezimbili ziyizimpondo ezimbili eziyisisekelo ezinohlangothi olulodwa.Ama-antenna anezinhlangothi ezimbili ayahlukahluka kakhulu, okuhlanganisa okufana neshidi (ucezu lwesikwele sensimbi), okufana ne-array (inqwaba yezingcezu ephethinini ehlelwe kahle enezinhlangothi ezimbili), kanye nezimo ezifana nezimpondo nezindishi.

I-base station antenna idlala indima ebaluleke kakhulu kulo lonke uhlelo lwezokuxhumana, ikakhulukazi isiteshi sokuxhumana njengendawo yokuxhumana.Ama-antenna asesiteshini asetshenziswa ngokujwayelekile afaka ama-antenna enziwe ngengilazi enziwe ngengilazi ezuzisa kakhulu, ama-antenna anezindandatho ezine (ama-antenna anendandatho eyisishiyagalombili), kanye nezimpondo eziqondisayo.

Ngokwalokhu okungenhla.Kukhona ezinye ezithinta umphumela we-antenna.Izinto zemvelo, njengezintaba, izihlahla, izindlu, njll. Kukhona nesimo sezulu, ngoba amafu abonisa uthi.Okwesibili ukugxambukela kwama-antenna.Ekugcineni, kukhona ezinye iziphazamiso kazibuthe kagesi, njengemibhoshongo yomakhalekhukhwini, imibhoshongo ye-TV, nemibhoshongo yokusakaza.
