RFMISOIbikoresho bya antene z'ihembe ry'uruziga
Antene yitwa vertically polarized antenna yerekeza ku muraba usohoka na antene, kandi icyerekezo cyayo cya polarization kiba gihagaze.
Icyerekezo cya polarization cy'umuraba kivuga icyerekezo cya vector y'amashanyarazi.
Bityo rero, icyerekezo cya polarization y'umuraba ni gihagaze, bivuze ko icyerekezo cya vector y'amashanyarazi ari gihagaze.
Mu buryo nk'ubwo, antene ifite polarike itambitse bivuze ko icyerekezo cy'imiraba kiri mu buryo butambitse, bivuze ko icyerekezo cy'amashanyarazi cy'imiraba isohora gihuye n'isi.
Polarization ihagaze na polarization itambitse byombi ni ubwoko bwa polarization ihagaze.
Icyo bita linear polarization bivuga polarization y'imiraba, ni ukuvuga icyerekezo cy'umurima w'amashanyarazi cyerekeza mu cyerekezo gihamye. Fixed bisobanura ko itazahinduka.
Antene ifite uruziga ihuza imiterere y'umuraba, ni ukuvuga icyerekezo cy'umuyoboro w'amashanyarazi, uzenguruka ku muvuduko umwe w uko igihe gihinduka.
None se, uburinganire bw'abakoresha ukuboko kw'ibumoso n'abakoresha ukuboko kw'iburyo bugenwa gute?
Igisubizo kiri mu maboko yawe.
Kuramo amaboko yombi, ibikumwe byabo byerekeza mu cyerekezo cy’aho umuraba ukwirakwira, hanyuma urebe intoki z’ukuboko zihengamye zizenguruka mu cyerekezo kimwe n’aho umuraba ukwirakwira.
Iyo ukuboko kw'iburyo ari kumwe, ni ukwihuza kw'iburyo; iyo ukuboko kw'ibumoso ari kumwe, ni ukwihuza kw'ibumoso.
Hanyuma, nzakoresha formula kugira ngo ngusobanurire. Noneho tuvuge ko hari imiraba ibiri ihuza umurongo umwe.
Icyerekezo kimwe cya polarization ni icyerekezo cya x naho amplitude ni E1; icyerekezo kimwe cya polarization ni icyerekezo cya y naho amplitude ni E2; imiraba yombi ikwirakwira mu cyerekezo cya z.
Ugereranije n'imiraba ibiri, ingufu z'amashanyarazi zose hamwe ni izi:
Ukurikije formula yavuzwe haruguru, hari uburyo bwinshi bushoboka:
(1) E1≠0, E2=0, hanyuma icyerekezo cya polarization y'umuraba w'indege ni x-axis
(2) E1=0, E2≠0, hanyuma icyerekezo cya polarization y'umuraba w'indege ni umurongo wa y
(3) Niba E1 na E2 byombi ari imibare nyayo atari 0, icyo gihe icyerekezo cya polarization y'umuraba w'indege kigize inguni ikurikira hamwe na x-axis:
(4) Iyo hari itandukaniro ry’icyiciro runaka hagati ya E1 na E2, nk'uko bigaragara ku ishusho iri hepfo, umuraba w’indege ushobora guhinduka umuraba uzunguruka w’iburyo cyangwa umuraba uzunguruka w’ibumoso.
Kugira ngo antene zizunguruka zifashe imiraba igororotse, na antene zizunguruka zifashe imiraba igororotse, ushobora kubyumva urebye ishusho iri hepfo.
Ariko se bite ku miraba izunguruka? Mu gihe cyo kubona uruziga, iboneka hakoreshejwe imiterere ibiri igororotse ifite itandukaniro ry'ibyiciro.
Kugira ngo umenye byinshi kuri antene, sura:
