Yego. Nyamara, sisitemu ya antenna yo hambere yakoreshaga ibiryo bigororotse, bitari insinga za coaxial.
Umugozi wa RF coaxial ukeneye kumvikana mubice bibiri.
RF: RF bivuga imirongo ya electromagnetic ishobora gukwirakwira mu kirere, kuva kuri 300kHz kugeza 300GHz.
RF ni radiyo yumurongo wa radiyo, amagambo ahinnye yumurongo muremure - uhinduranya amashanyarazi ya electronique.
Ibindi bisimburana bihindura munsi yincuro 1000 kumasegonda byitwa - imiyoboro yumurongo, kandi ko ibyo bihinduka inshuro zirenga 10000 kumasegonda byitwa high - umuyoboro mwinshi. RF nkiyi yo hejuru - inshuro nyinshi.
RF (300K - 300G) numuyoboro mwinshi murwego rwo hejuru (kurenza 10K).
Mubyigisho bya elegitoroniki, iyo umuyoboro unyuze mu kiyobora, umurima wa magneti uba ukikijwe nuyobora; iyo guhinduranya amashanyarazi bitembera mu kiyobora, umurima wa electromagnetic uhinduranya ukorwa hafi yuyobora. Ibi byitwa electromagnetic wave.
Imiyoboro ya electromagnetique ifite imirongo iri munsi ya 100kHz yakirwa nubutaka bwisi kandi ntishobora kwanduzwa neza. Nyamara, imiyoboro ya electromagnetique ifite imirongo iri hejuru ya 100kHz irashobora gukwirakwira mu kirere kandi ikagaragazwa na ionosire ku nkombe y’ikirere, bigatuma intera ndende -.
Twise hejuru - inshuro ya electromagnetic waves hamwe na - ubushobozi bwo kohereza intera ya radiyo (RF).
Ikoranabuhanga rya RF rikoreshwa cyane mu itumanaho ridafite umugozi; sisitemu ya tereviziyo ya kabili ikoresha itumanaho rya RF.
Umugozi wa Coaxial: Kubera ko abayobora bombi (umuyobozi w'imbere / umuyoboro w'imbere) badahuje imiterere y'ubutaka, hamwe n'umuyoboro umwe w'imbere uherereye ku murongo w'undi muyoboro w'inyuma wa silindrike, witwa "umugozi wa coaxial."
Ikiranga insinga za coaxial nuko umurima wa electromagnetique uba ufunzwe cyane nuyobora hanze, bikemerera gukoreshwa kumurongo mwinshi.
Icyitonderwa: Umuyoboro winyuma wumugozi wa coaxial ni umuyobora kandi urwego rukingira (rukora nk'umuzingi kandi rutanga ibikorwa byo kurwanya -).
Umugozi wa coaxial ukoreshwa mu kohereza ibimenyetso bya RF witwa "umugozi wa RF coaxial."
Ikimenyetso cyakiriwe na antenne cyoherezwa kumpera yimbere hifashishijwe umurongo wa federasiyo, kandi ibimenyetso bisohoka kuva kumpera yimbere nabyo byoherezwa mubikoresho bitandukanye byakira binyuze kumurongo ugaburira.
Muri iki gihe, dukunze kubona ibyokurya bihuza hamwe nogukwirakwiza bikoreshwa muri sisitemu yo kongera ibimenyetso nka minisiteri ya mbere - umurongo wa signal utagira umurongo (China Mobile, China Unicom, China Telecom, nibindi), tunel, hamwe nubutaka.
