Ibyerekeye antenne, hano kugirango nkubwire ~

Antenna, ishobora gukoreshwa mu kohereza ibimenyetso no kwakira ibimenyetso, irahindurwa, igasubiranamo, kandi irashobora gufatwa nka transducer, nigikoresho cyimbere hagati yumuzunguruko n'umwanya.Iyo bikoreshejwe mu kohereza ibimenyetso, ibimenyetso byumuvuduko mwinshi wamashanyarazi bitangwa nisoko yikimenyetso bihindurwamo imiraba ya electromagnetique mumwanya kandi ikoherezwa mubyerekezo runaka.Iyo ikoreshwa mu kwakira ibimenyetso, imiraba ya electromagnetic mumwanya ihindurwamo ibimenyetso byamashanyarazi hanyuma ikoherezwa kubakira binyuze mumigozi.

Antenne iyo ariyo yose ifite ibipimo bimwe na bimwe bishobora gusobanurwa neza, bishobora gukoreshwa mugusuzuma imikorere ya antene, harimo ibipimo biranga amashanyarazi hamwe nibikoresho biranga imashini.

Itondekanya rya antene

Antenna irashobora gushyirwa mubice ukurikije inzira zitandukanye, cyane cyane:

Gutondekanya ukoresheje: birashobora kugabanywa muri antenne y'itumanaho, antenne ya tereviziyo, antenne ya radar n'ibindi

Ukurikije umurongo wa bande ikora: urashobora kugabanywa muri antenne ngufi, antenne ultra-short-wave antenna, antenna ya microwave nibindi

Ukurikije ibyiciro byubuyobozi: birashobora kugabanywa muri antene ya byose, antenne yicyerekezo, nibindi

Ukurikije imiterere itondekanya: irashobora kugabanywamo antenne y'umurongo, antenne planari nibindi

Antenna yerekeza: Icyerekezo cya antenne kigarukira gusa kuri horizontal ya dogere 360.

Antenne ya Omnidirectional irashobora gukoreshwa kenshi mukwakira / kohereza ibimenyetso mubyerekezo byose icyarimwe.Ibi birashobora kwifuzwa niba ikimenyetso gikeneye kwakirwa / koherezwa mubyerekezo byose, nka hamwe na radio gakondo.Nyamara, hari igihe usanga icyerekezo cyikimenyetso kizwi cyangwa kigarukira.Kurugero, hamwe na telesikope ya radio, birazwi ko ibimenyetso bizakirwa mubyerekezo runaka (biva mumwanya), mugihe antenne ya omni-icyerekezo idakora neza mugutora ibimenyetso byoroheje biva mu nyenyeri.Muri iki gihe, antenne yicyerekezo hamwe na antenne yunguka irashobora gukoreshwa kugirango yakire ingufu zerekana ibimenyetso mubyerekezo runaka.

Urugero rwa antenne yerekeza cyane ni antenne ya Yagi.Ubu bwoko bwa antene ni inshuro zikoreshwa mu kohereza / kwakira ibimenyetso byitumanaho intera ndende mugihe icyerekezo cyibimenyetso byinjira cyangwa intego bizwi.Urundi rugero rwa antenne iyobora cyane ni antide ya mahembe yunguka.Iyi antenne ikoreshwa kenshi mugupima no gupima porogaramu, nko mugihe upima imikorere yindi antenne, cyangwa mugihe wakiriye / wohereje ibimenyetso mumurongo muremure wa waveguide.Antenne yubuyobozi irashobora kandi gukorwa mubishushanyo mbonera byoroheje byerekana isahani yoroheje yo guhimba byoroshye kumasoko asanzwe ya RF nka PCBS.Iyi antenne ya plaque isanzwe ikoreshwa mubitumanaho byabaguzi ninganda kuko usanga bihendutse kubikora kandi biremereye kandi bito.
