Munyika yeantenna, kune mutemo wakadaro.Kana a verticallypolarized antennainotumira, inogona kugamuchirwa chete neiyo vertically polarized antenna;kana antenna yakatwasuka polarized ichitumira, inogona chete kugashirwa nehorizontally polarized antenna;kana ruoko rworudyicircularly polarized antennainotumira, inogona chete kugamuchirwa nerudyi-rudyi denderedzwa polarized antenna;kana antenna yeruboshwe-ruboshwe inotenderera, inogona kugamuchirwa chete nerudyi-rudyi denderedzwa polarized antenna;Iyo denderedzwa polarized antenna inotapurirana uye inogona chete kugamuchirwa neruboshwe-ruboshwe denderedzwa polarized antenna.

RFMISOYakatenderedzwa polarized nyanga antenna zvigadzirwa
Iyo inonzi vertically polarized antenna inoreva wave unoburitswa neantenna, uye kutungamira kwayo kwepolarization kwakamira.
Polarization direction yemafungu inoreva gwara remagetsi.
Naizvozvo, iyo polarization inotungamira yemafungu yakamira, izvo zvinoreva kuti kutungamira kwemagetsi field vector kwakamira.
Saizvozvovo, antenna yakatwasuka polarized zvinoreva kuti mafambiro emasaisai akachinjika, zvichireva kuti nzvimbo yemagetsi yakanangana nemasaisai ainoburitsa inofanana nenyika.
Vertical polarization uye horizontal polarization ese ari maviri marudzi emutsara polarization.
Iyo inonzi linear polarization inoreva polarization yemafungu, ndiko kuti, kutungamira kwenzvimbo yemagetsi kunongedza munzira yakatarwa.Yakagadziriswa inoreva kuti haizoshanduki.
Iyo denderedzwa polarized antenna inoreva polarization yemafungu, ndiko kuti, kutungamira kwenzvimbo yemagetsi, iyo inotenderera pauniform angular velocity w kana nguva ichichinja.
Saka sei denderedzwa reruboshwe uye rekurudyi-ruoko rwerudyi rinotemwa?
Mhinduro iri nemaoko ako.
Bvisa maoko ese kunze, zvigunwe zvadzo zvakanongedza kwainofambiswa nemasaisai, wobva waona kuti ndeupi ruoko rwakakotama zvigunwe zvinotenderera nenzira imwechete nepolarization.
Kana ruoko rwerudyi rwakafanana, irwo rudyi-ruoko rwepolarization;kana ruoko rworuboshwe rwakafanana, i-left-handed polarization.
Zvadaro, ini ndichashandisa mafomula kuti ndikutsanangurire.Zvino ngatitii kune maviri linearly polarized masaisai.
Imwe nzira yepolarization ndiyo x kutungamira uye amplitude ndeye E1;imwe polarization kutungamira ndiyo y kutungamira uye amplitude ndeye E2;masaisai ose ari maviri anopararira achitevedza z direction.
Kukurira mafungu maviri, iyo yakazara magetsi munda ndeye:
Kubva pane fomula iri pamusoro, pane zvakawanda zvinogoneka:
(1) E1≠0, E2 = 0, ipapo iyo polarization kutungamira kweiyo ndege wave ndiyo x-axis.
(2) E1 = 0, E2≠0, ipapo iyo polarization kutungamira kweiyo ndege wave ndiyo y-axis.
(3) Kana E1 neE2 ari ese ari manhamba chaiwo uye asiri 0, saka iyo polarization kutungamira kweiyo ndege wave inoumba kona inotevera ine x-axis:
(4) Kana paine musiyano wechikamu pakati peE1 neE2, sezvaratidzwa pamufananidzo uri pazasi, iyo ndege inobhururuka inogona kuita ruoko rwerudyi rwakatenderedzwa polarized wave kana kuruboshwe-ruboshwe denderedzwa polarized wave.
Kuti antenna akatwasuka polarized agamuchire vertically polarized antennas, uye yakachinjika polarized antennas kuti igamuchire yakachinjika polarized mafungu, unogona kuzvinzwisisa nekutarisa pamufananidzo uri pazasi.
Asi zvakadini nemafungu ane circularized polarized?Mukuita kwekutora denderedzwa polarization, inowanikwa nekupfuura maviri mutsara polarizations ane chikamu mutsauko.
Kuti udzidze zvakawanda nezve antennas, ndapota shanya:
