Babban Gain L-Band Directional Karkashin Eriya /Helical Eriya

Eriya helical/Spiral eriya nau'in eriya ce ta musamman wacce zata iya watsawa da karɓar siginonin lantarki masu ƙarfi da ke jujjuya sararin samaniya. Irin wannan eriya yawanci ana amfani da ita a cikin tashoshin ƙasa don sadarwar tauraron dan adam kuma yana kunshe da karkatattun karfe tare da kyawawan halaye. Yawancin lokaci ana ciyar da ita ta hanyar kebul na coaxial, inda ainihin waya ta coaxial ke haɗa zuwa ƙarshen waya mai karkace kuma ana haɗa madubin waje zuwa ragar ƙarfe ko faranti. Siffofin radiation na eriya karkace suna da alaƙa da kewayen karkace ta: lokacin da kewayen ya fi ƙanƙanta da tsayin raƙuman raƙuman ruwa, babban jagorar radiation yana daidai da karkace axis; lokacin da kewaye ke kusa da tsayin raƙuman ruwa, mafi ƙarfi radiation yana bayyana a cikin al'amuran karkace.

Eriya Helical/Spiral eriya suna da fa'idodi masu zuwa:

1. Radiation yafi mayar da hankali a cikin axis shugabanci na eriya.
2. Mai ikon samar da raƙuman ruwa masu madauwari, tare da tsayayya da tasirin hanyoyi da yawa da tsangwama na sigina.
3. Rarraba na yanzu akan eriya yana nuna siffar igiyar ruwa mai tafiya, wanda ke taimakawa wajen cimma daidaitaccen tasirin radiation.
4. Rashin shigar da shigar yana kusa da tsantsar tsayin daka, wanda ke sauƙaƙa ƙirar hanyar sadarwar da ta dace kuma yana inganta inganci.
5. Yana da halayen watsa labarai kuma yana iya kiyaye ingantaccen aikin radiation a cikin kewayon mitar mai faɗi.

Saboda girman halayen su na lebur, kyakkyawan aikin polarization na madauwari, da kyakkyawan ƙarshen-wuta da iyawar wuta, an yi amfani da eriya mai ɗimbin yawa a fagage da yawa kamar sararin samaniya, yanayin yanayi, matsayi, da hanyoyin sadarwa. Tare da ci gaba da haɓaka fasahar sadarwar mara waya, ana sa ran ingantaccen aikin lantarki na eriyar helical zai ba su ƙarin aikace-aikace da sararin ci gaba a nan gaba.
