Microstrip eriyasabon nau'in microwave neeriyawanda ke amfani da igiyoyi masu ɗawainiya da aka buga akan madaidaicin dielectric azaman naúrar haskaka eriya. An yi amfani da eriya ta Microstrip a cikin tsarin sadarwar zamani saboda ƙananan girman su, nauyin nauyi, ƙananan bayanan martaba, da haɗin kai mai sauƙi.
Yadda eriyar microstrip ke aiki
Ka'idar aiki na eriyar microstrip ta dogara ne akan watsawa da radiation na igiyoyin lantarki. Yawanci ya ƙunshi facin radiation, dielectric substrate da farantin ƙasa. Ana buga facin radiation a saman ma'auni na dielectric, yayin da farantin ƙasa ya kasance a daya gefen dielectric substrate.
1. Radiation patch: Facin radiation wani maɓalli ne na eriyar microstrip. Siriri siririn tsiri ne na ƙarfe da ke da alhakin ɗauka da haskaka igiyoyin lantarki.
2. Dielectric substrate: Dielectric substrate yawanci ana yin shi da ƙananan hasara, kayan aiki masu mahimmanci-dielectric, irin su polytetrafluoroethylene (PTFE) ko wasu kayan yumbu. Ayyukansa shine tallafawa facin radiation kuma yayi aiki azaman matsakaici don yaduwar igiyoyin lantarki.
3. Farantin ƙasa: Farantin ƙasa shine ƙaramin ƙarfe mafi girma wanda yake a wancan gefen dielectric substrate. Yana samar da haɗin kai mai ƙarfi tare da facin radiation kuma yana ba da rarraba filin lantarki mai mahimmanci.
Lokacin da aka ciyar da siginar microwave cikin eriyar microstrip, yana samar da igiyar igiyar tsaye tsakanin facin radiation da farantin ƙasa, yana haifar da hasken raƙuman lantarki. Za'a iya daidaita ingancin radiation da ƙirar eriyar microstrip ta hanyar canza siffa da girman facin da halayen ma'auni na dielectric.

Bambanci tsakanin eriyar microstrip da eriyar faci
Eriya Patch wani nau'i ne na eriyar microstrip, amma akwai wasu bambance-bambance a cikin tsari da ƙa'idar aiki tsakanin su biyun:
1. Bambance-bambancen tsari:
Microstrip eriya: yawanci yana kunshe da facin radiation, dielectric substrate da farantin ƙasa. An dakatar da facin akan ma'aunin dielectric.
Eriya Patch: Abubuwan da ke haskakawa na eriyar faci ana haɗe kai tsaye zuwa ga ma'aunin wutar lantarki, yawanci ba tare da tsayayyen tsari ba.
2. Hanyar ciyarwa:
Eriyar Microstrip: Yawancin ciyarwar ana haɗa shi da facin mai haskakawa ta hanyar bincike ko layin microstrip.
Eriya mai faci: Hanyoyin ciyarwa sun fi bambanta, waɗanda zasu iya zama ciyarwar gefe, ciyarwar ramuka ko ciyarwar coplanar, da sauransu.
3. Ingantaccen Radiation:
Microstrip eriyar: Tun da akwai wani tazara tsakanin facin radiation da ƙasa farantin, za a iya samun wani adadin iska ratar asarar, wanda rinjayar da radiation yadda ya dace.
Eriyar Patch: Abubuwan da ke haskakawa na eriyar facin an haɗe su tare da ma'aunin wutar lantarki, wanda yawanci yana da ingancin hasken wuta.
4. Ayyukan bandwidth:
Eriyar Microstrip: bandwidth yana da ɗan kunkuntar, kuma bandwidth yana buƙatar haɓaka ta hanyar ingantaccen ƙira.
Eriya mai faci: Ana iya samun faffadan bandwidth ta hanyar zayyana sassa daban-daban, kamar ƙara haƙarƙarin radar ko amfani da sifofi masu yawa.
5.Lokacin aikace-aikace:
Microstrip eriyar: dace da aikace-aikace waɗanda ke da tsauraran buƙatu akan tsayin bayanin martaba, kamar sadarwar tauraron dan adam da sadarwar wayar hannu.
Faci eriya: Saboda bambancin tsarin su, ana iya amfani da su a cikin aikace-aikace daban-daban, gami da radar, LANs mara waya, da tsarin sadarwa na sirri.
