I-eriyali yeMicrostripluhlobo olutsha lwemicrowavei-eriyaliesebenzisa imicu yokuqhuba eprintiweyo kwi-dielectric substrate njengeyunithi emitha ye-eriyali. Ii-antenna ze-Microstrip zisetyenziswe ngokubanzi kwiinkqubo zonxibelelwano zanamhlanje ngenxa yobukhulu bazo obuncinci, ubunzima obulula, iphrofayili ephantsi, kunye nokudibanisa okulula.
Isebenza njani i-eriyali ye-microstrip
Umgaqo wokusebenza we-eriyali ye-microstrip usekwe kuthumelo kunye nemitha yemitha yamaza ombane. Ngokuqhelekileyo iqulethe i-radiation patch, i-dielectric substrate kunye ne-ground plate. I-patch ye-radiation ishicilelwe kumphezulu we-dielectric substrate, ngelixa i-plate yomhlaba ibekwe kwelinye icala le-dielectric substrate.
1. Isixhobo sokusasazeka kwemitha: Isixhobo sokusasazeka kwemitha siyinxalenye ephambili ye-eriyali ye-microstrip. Ngumcu wentsimbi obhityileyo onoxanduva lokubamba kunye nokukhupha amaza ombane.
2. I-Dielectric substrate: I-substrate ye-dielectric ngokuqhelekileyo yenziwe ngelahleko ephantsi, i-high-dielectric-constant materials, njenge-polytetrafluoroethylene (PTFE) okanye ezinye izinto ze-ceramic. Umsebenzi wayo kukuxhasa ipatch yemitha kwaye isebenze njengendawo yokusasaza i-electromagnetic wave.
3. Ipleyiti ephantsi: Ipleyiti yomhlaba ngumaleko wesinyithi omkhulu obekwe kwelinye icala le-dielectric substrate. Yenza i-capacitive coupling kunye ne-radiation patch kwaye ibonelela ngokusasazwa kwentsimi ye-electromagnetic.
Xa isignali ye-microwave ifakwe kwi-eriyali ye-microstrip, yenza amaza okuma phakathi kwepatshi yemitha kunye nepleyiti ephantsi, ekhokelela kwimitha yemitha yamaza ombane. Ukusebenza kwe-radiation kunye nepateni ye-eriyali ye-microstrip inokulungelelaniswa ngokutshintsha imilo kunye nobukhulu bepetshi kunye neempawu ze-dielectric substrate.

Umahluko phakathi kwe-eriyali ye-microstrip kunye ne-eriyali yokupakisha
I-eriyali yePatch luhlobo lwe-eriyali ye-microstrip, kodwa kukho umahluko othile kulwakhiwo kunye nomgaqo wokusebenza phakathi kwezi zimbini:
1. Umahluko kwisakhiwo:
I-antenna ye-Microstrip: ngokuqhelekileyo iqukethe i-radiation patch, i-dielectric substrate kunye neplate yomhlaba. I-patch imisiwe kwi-dielectric substrate.
I-antenna ye-Patch: I-antenna ye-radiation ye-patch antenna ifakwe ngokuthe ngqo kwi-dielectric substrate, ngokuqhelekileyo ngaphandle kwesakhiwo esimisiweyo esicacileyo.
2. Indlela yokutyisa:
I-eriyali yeMicrostrip: Ifidi idla ngokuqhagamshelwa kwipetshi yokusasazeka ngeprobes okanye imigca yemicrostrip.
I-antenna ye-Patch: Iindlela zokutyisa zahluke kakhulu, ezinokuthi zibe kukutya okusemacaleni, ukutya okufakwe kwi-slot okanye ukutya kwe-coplanar, njl.
3. Ukusebenza kakuhle kwemitha:
I-antenna ye-Microstrip: Ekubeni kukho i-gap ethile phakathi kwe-patch ye-radiation kunye ne-plate yomhlaba, kunokubakho umlinganiselo othile welahleko ye-air gap, echaphazela ukusebenza kakuhle kwe-radiation.
I-antenna ye-Patch: Isixhobo sokukhanya se-eriyali ye-patch idityaniswe ngokusondeleyo kunye ne-dielectric substrate, ehlala inokusebenza okuphezulu kwemitha.
4. Ukusebenza kobubanzi:
I-antenna ye-Microstrip: I-bandwidth incinci, kwaye i-bandwidth kufuneka inyuswe ngoyilo oluphuculweyo.
I-antenna ye-Patch: I-bandwidth ebanzi inokufezekiswa ngokuyila izakhiwo ezahlukeneyo, ezinjengokongeza iimbambo ze-radar okanye ukusebenzisa izakhiwo ezininzi.
5. Izihlandlo zokufaka isicelo:
I-antenna ye-Microstrip: ilungele izicelo ezineemfuno ezingqongqo kubude beprofayili, njengonxibelelwano lwesathelayithi kunye nonxibelelwano lweselula.
Ii-antenna ze-Patch: Ngenxa yokwahluka kwesakhiwo, zinokusetyenziswa kuluhlu olubanzi lwezicelo, kubandakanywa i-radar, ii-LAN ezingenazintambo, kunye neenkqubo zonxibelelwano lomntu.
Ukuququmbela
Ii-eriyali zeMicrostrip kunye nee-eriyali eziziqwenga zombini zisetyenziswa ngokuqhelekileyo ii-eriyali ze-microwave kwiinkqubo zonxibelelwano zanamhlanje, kwaye zineempawu zazo kunye nezinto eziluncedo. I-antennas ze-Microstrip zigqwesa kwizicelo ze-space-constrained ngenxa yeprofayili yazo ephantsi kunye nokudibanisa okulula. Ii-eriyali zePatch, kwelinye icala, zixhaphake kakhulu kwizicelo ezifuna i-bandwidth ebanzi kunye nempumelelo ephezulu ngenxa yokusebenza kwazo okuphezulu kwemitha kunye nokuyilwa.
