Izinto ezichaphazela i-eriyali

1. Ngokobume bomsebenzi, inokwahlulwa ibe yi-antenna yokudlulisa kunye nokufumana i-antenna.

2. Ngokwenjongo, inokwahlulwa ibe zii-antenna zonxibelelwano, ii-antenna zokusasaza, ii-antenna zeTV, ii-antenna ze-radar, njl.

3. Ngokobude obusebenzayo, inokohlulwa ibe yi-antenna ende yamaza, i-eriyali yamaza ende, i-eriyali yamaza aphakathi, i-eriyali yamaza amaza amafutshane, i-eriyali emfutshane ye-ultra, i-antenna ye-microwave, njl.

4. Ngokutsho kwesakhiwo kunye nomgaqo wokusebenza, unokwahlula kwii-antenna zomgca kunye ne-antennas surface.Iimpawu zeempawu ezichaza i-eriyali yipatheni, i-directivity coefficient, inzuzo, i-impedance yegalelo, ukusebenza kakuhle kwemitha, i-polarization kunye nokuphindaphinda.

Ii-eriyali zinokwahlulwa zibe ziindidi ezimbini ngokwenani lemilinganiselo: i-eriyali ene-dimensional enye kunye ne-two-dimensional eriyali.Ii-eriyali ezinomgangatho omnye zenziwe ngeengcingo ezininzi.Ezi ngcingo mhlawumbi imigca ethe ngqo esetyenziswa kwiselula, okanye ezinye iimilo smart, kanye njengeentambo.Iindlebe ezindala zemvundla bezisetyenziswa ngaphambili kwiiseti zeTV.I-Monopole kunye nee-eriyali ezinenqanaba ezimbini zezona zisisiseko ezinomda omnye.Ii-antenna ezi-two-dimensional zihluka ngokubanzi, kubandakanywa i-sheet-like (i-square piece of metal), i-array-like (iqela leengqungquthela kwipatheni ye-dimensional ehlelwe kakuhle), kunye neembombo ezifana nophondo kunye nesitya.

I-eriyali yesitishi esisisiseko idlala indima ebaluleke kakhulu kuyo yonke inkqubo yonxibelelwano, ngakumbi isikhululo sonxibelelwano njengendawo yonxibelelwano.Ii-eriyali zesiseko ezisetyenziswa ngokuqhelekileyo ziquka i-eriyali yeglasi eyomeleziweyo yeplastiki enenzuzo ephezulu, i-eriyali ezine-ring-ring array (ii-eriyali ezine-array esibhozo), kunye ne-eriyali ezalathisayo.

Ngokutsho koku ngasentla.Kukho ezinye ezichaphazela umphumo we-eriyali.Izinto zendalo, ezifana neentaba, imithi, izindlu, njl. Kukho nemozulu, kuba amafu abonakalisa i-eriyali.Okwesibini kukuphazamiseka okufanayo kwee-eriyali.Okokugqibela, kukho ezinye iziphazamiso ze-electromagnetic, ezinje ngeenqaba zeselfowuni, iinqaba zeTV, kunye neenqaba zokusasaza.
