Munyika yeantenna, kune mutemo wakadaro. Kana antenna yakamirakanyanga ine polarizedinotumira, inogona kugamuchirwa chete neantenna yakamiswa yakatwasuka; kana antenna yakamiswa yakatwasuka, inogona kugamuchirwa chete neantenna yakamiswa yakatwasuka; kana ruoko rwerudyikanyanga yakatenderera ine polarizedInotumira, inogona kugamuchirwa chete neantenna yakatenderera ine polarized kurudyi; kana antenna yakatenderera ine polarized kuruboshwe ikatamiswa, inogona kugamuchirwa chete neantenna yakatenderera ine polarized kurudyi; Antenna yakatenderera ine polarized inotumira uye inogona kugamuchirwa chete neantenna yakatenderera ine polarized kuruboshwe.

RFMISOZvigadzirwa zveantenna zvenyanga dzakatenderedzwa dzakatenderedzwa
Antena inonzi vertically polarized inoreva mafungu anoburitswa neantena, uye gwara rayo re polarization rakamira.
Nzira yekupokana kwemafungu inoreva nzira yemagetsi emagetsi.
Saka, nzira yekupolarization yemafungu yakamira, zvinoreva kuti nzira ye electric field vector yakamira.
Saizvozvowo, antenna yakatenderedzwa nepakati zvinoreva kuti divi remafungu rakatambanudzwa, zvinoreva kuti divi remagetsi remafungu aanoburitsa rakafanana nenyika.
Polarization yakatwasuka uye polarization yakatwasuka dzose dziri mbiri mhando dzepolarization yakatwasuka.
Kunonzi linear polarization zvinoreva polarization yemafungu, kureva kuti, divi remagetsi rinonongedza munzira yakatarwa. Fixed zvinoreva kuti harizoshanduke.
Antena yakatenderera inoreva kupolarization kwemafungu, kureva, kutungamira kwesimba remagetsi, iro rinotenderera nekufamba kweangular kwakafanana w sezvo nguva ichichinja.
Saka polarization yedenderedzwa yeruoko rweruboshwe neruoko rwerudyi inoonekwa sei?
Mhinduro yacho iri nemaoko ako.
Bvisa maoko ese ari maviri, zvigunwe zvawo zvakanongedzera kwakanangana nekupararira kwemafungu, wobva waona kuti ndezvipi zvigunwe zveruoko zvakakotama zvinotenderera nenzira imwecheteyo ne polarization.
Kana ruoko rwerudyi rwakafanana, zvinoreva polarization yeruoko rwerudyi; kana ruoko rweruboshwe rwakafanana, zvinoreva polarization yeruoko rweruboshwe.
Zvadaro, ndichashandisa mafomura kukutsanangurirai. Zvino ngatitii kune mafungu maviri ane polarized linearly.
Nzira imwe chete yekupokana ndiyo nzira ye x uye amplitude ndiyo E1; nzira imwe yekupokana ndiyo nzira ye y uye amplitude ndiyo E2; mafungu ese ari maviri anopararira achitevedza nzira ye z.
Kupfuura mafungu maviri aya, simba rese remagetsi nderiri:
Kubva pane fomura iri pamusoro apa, pane mikana yakawanda:
(1) E1≠0, E2=0, saka nzira yekupolarization ye plane wave ndiyo x-axis
(2) E1=0, E2≠0, saka nzira yekupolarization ye plane wave ndiyo y-axis
(3) Kana E1 naE2 dziri nhamba chaidzo kwete 0, saka nzira yekupolarization ye plane wave inoumba kona inotevera ne x-axis:
(4) Kana paine musiyano wechikamu pakati peE1 neE2, sezvakaratidzwa mumufananidzo uri pazasi, plane wave inogona kuva right-hand polarized wave kana rounded polarized wave.
Kuti maantenna akatenderedzwa nemativi maviri agamuchire mafungu akatenderedzwa nemativi maviri, uye maantenna akatenderedzwa nemativi maviri agamuchire mafungu akatenderedzwa nemativi maviri, unogona kunzwisisa nekutarisa mufananidzo uri pazasi.
Asi zvakadini nemafungu akatenderera? Mukuita kwekugadzira denderedzwa repolarization, inowanikwa nekuisa panzvimbo pemapolarization maviri ane musiyano wezvikamu.
Kuti udzidze zvakawanda nezve antenna, ndapota shanyira:
