Dipole ifunze ni antene igizwe n'udukingirizo tubiri tubangikanye duhujwe ku mpera zombi, tugakora imiterere ifunze, aho amashanyarazi ari hagati. Uburebure bwose bwa antene ni igice cy'uburebure bw'umurambararo, niyo mpamvu yitwa antene ya dipole ifunze igice cy'umuraba.
Ingano y'inshuro
Antene ya dipole ifite umuraba ufunze ikora ku ntera iri hagati ya 3 kHz na 300 GHz, kandi ikoreshwa cyane cyane mu byuma byakira televiziyo.
Imiterere n'amahame ngenderwaho y'imikorere ya Dipole ya Half-Wave Folded
Ubwo bwoko bwa antene bukunze gukoreshwa hamwe na antene za array kugira ngo bwongere impedance y'injira aho itumanaho rigera. Uburyo busanzwe bwo gukoreshwa ni antene ya Yagi. Ishusho iri hepfo igaragaza antene ya dipole ifite igice cy'umuraba.
Ugereranyije na antene isanzwe ya dipole, antene ya dipole ifunze itanga indi conductor iringaniye (ni ukuvuga indi nsinga cyangwa inkoni). Mu gushyira conductor nyinshi ziringaniye iruhande rw'izindi zifite insulation hagati yazo, antene yo mu bwoko bwa array ishobora gukorwa.
Ishusho iri hepfo igaragaza ihame ry'imikorere ya antene ya dipole ifite igice cy'umuraba ifunze iyo ishyushye.
Iyo umurambararo w'umuyoboro mukuru w'amashanyarazi ari umwe n'uwa kondakita ingana muri dipole ifunze, impedance y'aho antene inyura yiyongeraho incuro enye (kare ya ebyiri). Uku kwiyongera kw'impedance y'amashanyarazi ni yo mpamvu nyamukuru ituma antene ifunze ya dipole ikoreshwa cyane. Bitewe n'imiterere yayo ifite imiyoboro ibiri, impedance yayo isanzwe ni hafi 300 Ω.
Uburyo bwo gutanga imirasire
Imiterere y'imirasire ya dipole ifite igice cy'umuraba isa n'iya antene ifite igice cy'umuraba. Ishusho iri hepfo igaragaza imiterere y'imirasire y'uruhererekane rw'imirasire y'uruhererekane rw'umuraba.
Antene ya dipole ifite umuraba ufunze ikoreshwa mu bikorwa aho hakenewe kohereza ingufu nyinshi kandi aho hakenewe impedance nyinshi.
Iyi dipole ifunze ni yo kintu cy’ingenzi gitanga urumuri muri antene ya Yagi. Ishusho iri hepfo igaragaza antene ya Yagi (izaganirwaho birambuye nyuma). Muri iyi antene, aho itumanaho rihurira hahujwe na dipole ifunze nk'igice cy'ingenzi. Mu myaka mike ishize, ubwo bwoko bwa antene bwakoreshejwe cyane mu kwakira televiziyo.
Izi zikurikira ni inyungu za antene ya dipole ifite umuraba ugonganye.
1.Yakira ibimenyetso biringaniye.
2. Ifata ibimenyetso byifuzwa bivuye ku murongo runaka w'amajwi nta gutakaza ubuziranenge.
3. Dipole ipfunyitse yongera imbaraga z'ikimenyetso.
