Ezweni le-antenna, kukhona umthetho onjalo. Umai-antenna ehlanganisiweidlulisa, ingamukelwa kuphela yi-antenna evundlile ngokuvundlile; lapho i-antenna evundlile ngokuvundlile idlulisa, ingamukelwa kuphela yi-antenna evundlile ngokuvundlile; lapho isandla sokudlai-antenna egobile eyindilingaidlulisa, ingamukelwa kuphela yi-antenna egobile eyisiyingi esesandleni sokudla; lapho i-antenna egobile eyisiyingi esesandleni sokudla idlulisa, ingamukelwa kuphela yi-antenna egobile eyisiyingi esesandleni sokudla; I-antenna egobile eyisiyingi iyadlulisa futhi ingamukelwa kuphela yi-antenna egobile eyisiyingi esesandleni sokudla.

I-antenna ebizwa ngokuthi i-vertical polarized ibhekisela kugagasi elikhishwa yi-antenna, futhi isiqondiso sayo se-polarization siqondile.
Isiqondiso se-polarisation segagasi sibhekisela esiqondisweni se-vector yensimu kagesi.
Ngakho-ke, isiqondiso se-polarization segagasi siqondile, okusho ukuthi isiqondiso se-electric field vector siqondile.
Ngokufanayo, i-antenna evundlile isho ukuthi isiqondiso samagagasi sivundlile, okusho ukuthi isiqondiso sensimu kagesi samagagasi esiwakhiphayo sihambisana nomhlaba.
Ukuphola okuqondile kanye nokuphola okuvundlile kokubili kuyizinhlobo zokuphola okuqondile.
Okubizwa ngokuthi i-linear polarization kubhekisela ku-polarization yamagagasi, okungukuthi, isiqondiso sensimu kagesi sikhomba ohlangothini oluqondile. I-Fixed isho ukuthi ngeke ishintshe.
I-antenna egobile eyindilinga ibhekisela ekugobileni kwegagasi, okungukuthi, isiqondiso sensimu kagesi, esijikeleza ngesivinini se-angular esifanayo u-w njengoba isikhathi sishintsha.
Ngakho-ke ukuhlukaniswa okujikelezayo kwesandla sobunxele nesandla sokudla kunqunywa kanjani?
Impendulo itholakala ngezandla zakho.
Khipha izandla zombili, izithupha zazo zikhomba ohlangothini lokusabalala kwamagagasi, bese ubona ukuthi yimiphi iminwe yesandla egobile ejikeleza ohlangothini olufanayo nokwahlukana.
Uma isandla sokunene sifana, kuba ukuhlukaniswa kwesandla sokunene; uma isandla sokhohlo sifana, kuba ukuhlukaniswa kwesandla sokhohlo.
Okulandelayo, ngizosebenzisa amafomula ukukuchazela. Manje ake sithi kukhona amagagasi amabili ahlukaniswe ngomugqa.
Isiqondiso esisodwa se-polarization siyisiqondiso sika-x kanti i-amplitude ingu-E1; isiqondiso esisodwa se-polarization siyisiqondiso sika-y kanti i-amplitude ingu-E2; womabili amagagasi asakazeka ngesiqondiso sika-z.
Uma kuqhathaniswa namagagasi amabili, insimu kagesi iyonke yile:
Kusukela kufomula engenhla, kunezindlela eziningi:
(1) E1≠0, E2=0, bese isiqondiso se-polarization segagasi lendiza siyi-x-axis
(2) E1=0, E2≠0, bese isiqondiso se-polarization segagasi lendiza siyi-y-axis
(3) Uma u-E1 no-E2 kuyizinombolo zangempela hhayi u-0, khona-ke isiqondiso se-polarization segagasi lendiza sakha i-engeli elandelayo nge-x-axis:
(4) Uma kukhona umehluko wesigaba esithile phakathi kwe-E1 ne-E2, njengoba kuboniswe esithombeni esingezansi, igagasi lendiza lingaba igagasi eliyindilinga eliyindilinga eliyindilinga noma igagasi eliyindilinga ...
Ukuze ama-antenna ahlukaniswe ngokuvundlile athole amagagasi ahlukaniswe ngokuvundlile, kanye nama-antenna ahlukaniswe ngokuvundlile athole amagagasi ahlukaniswe ngokuvundlile, ungakuqonda ngokubheka isithombe esingezansi.
Kodwa kuthiwani ngamagagasi ahlukaniswe ngendilinga? Enqubweni yokuthola i-polarization eyindilinga, itholakala ngokufaka esikhundleni i-polarizations ezimbili eziqondile ezinomehluko wesigaba.
Ukuze ufunde kabanzi ngama-antenna, sicela uvakashele:
