Antenna na Yagi eriya ce mai amfani da ƙarshen wuta wadda ta ƙunshi oscillator mai aiki (yawanci oscillator mai naɗewa), mai nuna haske mai aiki, da kuma daraktoci da dama masu aiki da aka shirya a layi ɗaya. A shekarun 1920, Hidetsugu Yagi da Taiki Uta daga Jami'ar Tohoku da ke Japan sun ƙirƙiro wannan eriya, wadda aka sani da "Antenna na Yagi Uta" ko kuma kawai "Antenna na Yagi".

Halaye

1. Ƙarfin alkibla: Eriya tana da kyakkyawan alkibla kuma tana iya mai da hankali kan raƙuman rediyo a wani takamaiman alkibla. Matsakaicin alkiblar hasken iri ɗaya ce da ta darakta, tana rage cunkoso da tsangwama a cikin alkiblar da ba ta da manufa.
2. Ƙara riba: Idan aka kwatanta da eriya ta dipole, eriya ta ƙaho tana da ƙarin riba kuma tana iya kama sigina masu nisa, inganta ingancin karɓa da tsabta.
3. Tsarin da ya sauƙaƙa: ya ƙunshi masu juyawa masu aiki, masu nuna haske, da kuma wasu masu gudanarwa masu motsi waɗanda aka tsara a layi ɗaya, tsarin yana da sauƙi, kayan suna da sauƙin samu, farashin yana da ƙasa, kuma yana da sauƙi, mai ƙarfi, kuma yana da sauƙin ciyarwa.

Aikace-aikace

1. Fagen sadarwa: Eriya ta ƙaho ta RF da ake amfani da ita don sadarwa ta gajeren zango da ta gajeren zango, kamar sadarwa ta rediyo mai nisa, kuma ana iya amfani da ita azaman eriya ta waje don amplifiers na siginar wayar hannu don haɓaka siginar wayar hannu. Tana iya faɗaɗa kewayon ɗaukar hoto da inganta ƙarfin sigina a cikin hanyoyin sadarwar Wi-Fi, wanda ya dace da haɗa gine-gine masu nisa ko faɗaɗa ɗaukar hoto mai girma.
2. A fannin watsa labarai da talabijin, ana amfani da eriya ta ƙaho ta microwave a matsayin eriya mai karɓar talabijin, wadda za ta iya karɓar siginar talabijin a takamaiman alkibla kuma ta inganta tasirin karɓa.
3. Filin radar: Saboda yanayinsa na alkibla da kuma kamawa, ana iya amfani da eriya ta ƙaho mai tsawon milimita don gano abubuwan da ake hari a cikin tsarin radar.
4. Sauran fannoni: Eriya ta ƙaho ta Mm tana da aikace-aikace a masana'antu, tsarin tattara bayanai da sa ido (SCADA), da kuma dalilai na kimiyya da na likitanci, kamar sadarwa mara waya tsakanin kayan aikin tattara bayanai daga nesa da na sa ido, da kuma karɓar sigina da watsawa a wasu gwaje-gwajen kimiyya.
An yi amfani da eriya ta Yagi sosai a fannoni da dama na sadarwa ta waya saboda sauƙin tsarinta, ƙarancin farashin masana'antu, da kuma kyakkyawan aiki.

QualwaveKayayyakin Antennas na Yagi suna rufe kewayon mita har zuwa 173MHz. Muna bayar da eriya ta ƙaho ta gain na yau da kullun na gain 7dBi, da kuma eriya ta ƙaho mai siffar polarized guda biyu bisa ga buƙatun abokan ciniki.
