Ingancin aneriyayana nufin ikon eriya don canza ƙarfin shigar da wutar lantarki zuwa makamashi mai haske.A cikin sadarwa mara waya, ingancin eriya yana da tasiri mai mahimmanci akan ingancin watsa sigina da amfani da wutar lantarki.
Ana iya bayyana ingancin eriya ta wannan dabara:
Inganci = (Ƙarfin Radiated / Ƙarfin shigarwa) * 100%
Daga cikin su, Radiated Power shine makamashin lantarki da eriya ke haskakawa, kuma ikon shigar da ita ita ce shigar da makamashin lantarki zuwa eriya.
Abubuwan da yawa suna shafar ingancin eriya, gami da ƙirar eriya, abu, girman, mitar aiki, da sauransu. Gabaɗaya magana, mafi girman ingancin eriyar, gwargwadon yadda zai iya canza shigar da wutar lantarki zuwa makamashi mai haske, ta haka ne. inganta ingancin watsa sigina da rage yawan amfani da wutar lantarki.
Don haka, inganci muhimmin mahimmancin la'akari ne lokacin ƙira da zaɓin eriya, musamman a aikace-aikacen da ke buƙatar watsa nisa ko suna da ƙaƙƙarfan buƙatu akan amfani da wutar lantarki.
1. Ingantaccen Eriya
Hoto 1
Za'a iya bayyana ma'anar ingancin eriya ta amfani da Hoto 1.
Ana amfani da jimlar ingancin e0 don ƙididdige asarar eriya a shigarwar da cikin tsarin eriya.Dangane da Hoto na 1 (b), waɗannan asarar na iya kasancewa saboda:
1. Tunani saboda rashin daidaituwa tsakanin layin watsawa da eriya;
2. Gudanarwa da asarar dielectric.
Ana iya samun jimlar ingancin eriya daga wannan dabara:
Wato, jimlar ingantaccen aiki = samfurin rashin daidaituwa daidai, ingancin madugu da ingancin dielectric.
Yawancin lokaci yana da matukar wahala a ƙididdige ingancin gudanarwa da ingancin dielectric, amma ana iya ƙaddara su ta hanyar gwaje-gwaje.Duk da haka, gwaje-gwaje ba za su iya bambanta asarar biyu ba, don haka za a iya sake rubuta dabarar da ke sama kamar:
ecd shine ingancin radiation na eriya kuma Γ shine ma'aunin tunani.
2. Riba da Ganewar Riba
Wani ma'auni mai amfani don kwatanta aikin eriya shine riba.Duk da cewa ribar eriya tana da alaƙa da kai tsaye, siga ce da ke la'akari da ingancin eriya da kai tsaye.Jagoranci siga ce kawai wanda ke bayyana halayen jagoranci na eriya, don haka ana ƙaddara ta kawai ta tsarin radiation.
An ayyana ribar eriya a ƙayyadaddun shugabanci a matsayin "sau 4π rabon ƙarfin radiation a wannan hanyar zuwa jimillar ƙarfin shigarwa."Lokacin da ba a kayyade alkibla ba, ana samun ribar da ake samu a mafi girman tasirin radiation gaba ɗaya.Don haka, akwai gabaɗaya:
Gabaɗaya, yana nufin ribar dangi, wanda aka ayyana a matsayin "raɗin samun wutar lantarki a ƙayyadaddun shugabanci zuwa ikon eriyar tunani a cikin hanyar tunani".Dole ne ƙarfin shigar da wannan eriya ya zama daidai.Eriyar tunani na iya zama vibrator, ƙaho ko wata eriya.A mafi yawan lokuta, ana amfani da tushen wurin da ba na gaba ba azaman eriyar tunani.Saboda haka:
Dangantakar da ke tsakanin jimillar wutar da ke haskakawa da jimillar ikon shigarwa ita ce kamar haka:
Bisa ga ma'auni na IEEE, "Gain ba ya haɗa da asara saboda rashin daidaituwa (asarar tunani) da rashin daidaituwa na polarization (asarar)."Akwai ra'ayoyi guda biyu na riba, ɗayan ana kiransa riba (G) ɗayan kuma ana kiransa achievable gain (Gre), wanda ke la'akari da asarar hasara.
Dangantakar da ke tsakanin riba da shugabanci ita ce:
Idan eriya ta yi daidai da layin watsawa, wato, impedance shigar da eriya Zin daidai yake da sifa ta Zc na layin (|Γ| = 0), to riba da ribar da za a iya samu daidai suke (Gre = G). ).
