Antenna y'ihembe ni iki?Ni ayahe mahame nyamukuru akoreshwa?

Antenna y'ihembeni antenne yubuso, antenne ya microwave hamwe nuruziga cyangwa urukiramende rwambukiranya aho terminal ya waveguide ifungura buhoro buhoro.Nubwoko bukoreshwa cyane bwa antenna ya microwave.Imirasire yacyo igenwa nubunini bwumunwa nubwoko bwikwirakwizwa.Muri byo, ingaruka z'urukuta rw'amahembe ku mirasire zirashobora kubarwa ukoresheje ihame ryo gutandukanya geometrike.Niba uburebure bw'ihembe budahindutse, ubunini bwubuso bwumunwa hamwe na quadratic fase itandukaniro biziyongera uko inguni ifungura amahembe yiyongera, ariko inyungu ntizahinduka nubunini bwubuso bwumunwa.Niba ukeneye kwagura imirongo yumurongo wa disikuru, ugomba kugabanya imitekerereze ku ijosi no kumunwa wumuvugizi;kwigaragaza bizagabanuka uko ubunini bwumunwa bwiyongera.Imiterere ya antenne yamahembe iroroshye, kandi igishushanyo kiroroshye kandi cyoroshye kugenzura.Mubisanzwe bikoreshwa nka antenne yo hagati.Parabolike yerekana amahembe antenne ifite intera yagutse, lobes zo hepfo hamwe nubushobozi buhanitse bikoreshwa mugutumanaho kwa microwave.

Imirasire ya antenne yamahembe irashobora kubarwa uhereye kumurima ukoresheje ihame rya Huygens.Umwanya wubuso bwumunwa ugenwa nubunini bwumunwa hamwe nuburyo bwo gukwirakwiza amahembe.Inyigisho ya geometrike irashobora gukoreshwa mukubara ingaruka zurukuta rwamahembe kumirasire, kugirango igishushanyo kibarwa nagaciro kapimwe gishobora kuba cyumvikanye neza kugeza kuruhande rwa kure.Ibiranga imirasire bigenwa nubunini no gukwirakwiza umurima hejuru yumunwa, mugihe inzitizi igenwa no kwerekana ijosi ryumuvugizi (intangiriro yo guhagarika) hamwe nubuso bwumunwa.Iyo uburebure bw'ihembe buhoraho, niba impande zifungura ihembe zigenda ziyongera buhoro buhoro, ubunini bwubuso bwumunwa hamwe na quadratic phase itandukanya nabyo biziyongera icyarimwe, ariko inyungu ntabwo yiyongera icyarimwe nubunini bwa umunwa hejuru, kandi hari inyungu nigiciro kinini.Ubunini bwumunwa, umuvugizi ufite ingano yitwa umuvugizi mwiza.Amahembe asanzwe hamwe namahembe ya piramide akwirakwiza imiraba ya serefegitura, mugihe amahembe ameze nkabafana afungura hejuru yubuso bumwe (E cyangwa H hejuru) akwirakwiza imiraba ya silindrike.Ubuso bwumunwa wamahembe numurima ufite itandukaniro rya quadratic.Ingano ya fonctionnement ya quadratic ifitanye isano n'uburebure bw'ihembe n'ubunini bw'akanwa.

Antenne yamahembe ikoreshwa mubice bikurikira: 1. Kugaburira telesikopi nini ya radio, kugaburira antenne kugaburira sitasiyo ya satelite, hamwe na antenne yerekana itumanaho rya microwave;2. Antenne yibice kubice byiciro;3. Antenne Mubipimo, antene yamahembe ikoreshwa nkurwego rusanzwe rwa kalibrasi no kwipimisha izindi antene yunguka cyane.
