I-antenna ye-microstripluhlobo olutsha lwe-microwavei-antennaesebenzisa imicu yokuhambisa umbane eprintiweyo kwi-dielectric substrate njengeyunithi yokurhawuzelela i-antenna. Ii-antenna ze-microstrip zisetyenziswa kakhulu kwiinkqubo zonxibelelwano zanamhlanje ngenxa yobukhulu bazo obuncinci, ubunzima obulula, iprofayili ephantsi, kunye nokudibanisa okulula.
Indlela esebenza ngayo i-antenna ye-microstrip
Umgaqo osebenzayo we-microstrip antenna usekelwe ekudlulisweni nasekukhanyeni kwamaza e-electromagnetic. Ihlala iqulathe i-radiation patch, i-dielectric substrate kunye ne-ground plate. I-radiation patch iprintwa kumphezulu we-dielectric substrate, ngelixa i-ground plate ikwelinye icala le-dielectric substrate.
1. I-Radiation patch: I-radiation patch yinxalenye ebalulekileyo ye-microstrip antenna. Yi-strip encinci yesinyithi enoxanduva lokubamba nokukhupha amaza e-electromagnetic.
2. I-Dielectric substrate: I-dielectric substrate idla ngokwenziwa ngezinto ezingasebenzi kakuhle, ezihlala zisebenza rhoqo kwi-dielectric, ezifana ne-polytetrafluoroethylene (PTFE) okanye ezinye izinto ze-ceramic. Umsebenzi wayo kukuxhasa i-radiation patch kwaye isebenze njengendawo yokusasazwa kwamaza e-electromagnetic.
3. Ipleyiti engaphantsi komhlaba: Ipleyiti engaphantsi komhlaba lulwaleko olukhulu lwesinyithi olukwelinye icala le-dielectric substrate. Yenza i-capacitive coupling kunye ne-radiation patch kwaye ibonelela ngosasazo olufunekayo lwentsimi ye-electromagnetic.
Xa isignali ye-microwave ifakwa kwi-antenna ye-microstrip, yenza i-standing wave phakathi kwe-radiation patch kunye ne-ground plate, nto leyo ebangela i-radiation yamaza e-electromagnetic. Ukusebenza kakuhle kwe-radiation kunye nepatheni ye-antenna ye-microstrip kunokulungiswa ngokutshintsha imo kunye nobukhulu be-patch kunye neempawu ze-dielectric substrate.

Umahluko phakathi kwe-antenna ye-microstrip kunye ne-antenna ye-patch
I-antenna ye-patch luhlobo lwe-antenna ye-microstrip, kodwa kukho umahluko othile kwisakhiwo kunye nomgaqo wokusebenza phakathi kwezi zimbini:
1. Umahluko kwisakhiwo:
I-antenna ye-Microstrip: idla ngokuba ne-radiation patch, i-dielectric substrate kunye ne-ground plate. I-patch ixhonywe kwi-dielectric substrate.
I-antenna yepetshi: Into ekhupha imitha ye-antenna yepetshi incamathele ngqo kwi-substrate ye-dielectric, ngesiqhelo ayinasakhiwo esicacileyo esixhonyiweyo.
2. Indlela yokondla:
I-antenna ye-Microstrip: I-feed idla ngokudityaniswa ne-patch ekhupha imitha ngokusebenzisa ii-probes okanye imigca ye-microstrip.
I-antenna yePatch: Iindlela zokutya zahlukahlukene ngakumbi, ezinokuba kukutya okunomphetho, ukutya okutyiwayo okanye ukutya okufana ne-coplanar, njl.
3. Ukusebenza kakuhle kwemisebe:
I-antenna ye-Microstrip: Ekubeni kukho umsantsa othile phakathi kwe-radiation patch kunye ne-ground plate, kunokubakho ukulahleka komsantsa othile womoya, nto leyo echaphazela ukusebenza kakuhle kwe-radiation.
I-antenna yepetshi: Into ekhupha imitha ye-antenna yepetshi idityaniswe ngokusondeleyo ne-dielectric substrate, edla ngokuba nokusebenza kakuhle kwemitha.
4. Ukusebenza kwe-bandwidth:
I-antenna ye-Microstrip: I-bandwidth incinci kakhulu, kwaye i-bandwidth kufuneka yonyuswe ngoyilo olucwangcisiweyo.
I-antenna yepetshi: I-bandwidth ebanzi inokufezekiswa ngokuyila izakhiwo ezahlukeneyo, njengokongeza iimbambo zeradar okanye ukusebenzisa izakhiwo ezineeleya ezininzi.
5. Izihlandlo zokusetyenziswa:
I-antenna ye-Microstrip: ifanelekile kwizicelo ezineemfuno ezingqongqo zokuphakama kweprofayili, njengonxibelelwano lwesathelayithi kunye nonxibelelwano lweselula.
Ii-antenna zepetshi: Ngenxa yokwahluka kwazo ngokwesakhiwo, zingasetyenziswa kuluhlu olubanzi lwezicelo, kubandakanya i-radar, ii-LAN ezingenazingcingo, kunye neenkqubo zonxibelelwano lomntu ngamnye.
Ukuququmbela
Ii-antenna ze-Microstrip kunye nee-antenna ze-patch zombini zii-antenna ze-microwave ezisetyenziswa kakhulu kwiinkqubo zonxibelelwano zanamhlanje, kwaye zineempawu zazo kunye neenzuzo zazo. Ii-antenna ze-Microstrip zibalaseleyo kwizicelo ezixinzelelweyo ngenxa yokuba azibonakali kakuhle kwaye kulula ukuzidibanisa. Ii-antenna ze-patch, kwelinye icala, zixhaphake kakhulu kwizicelo ezifuna i-bandwidth ebanzi kunye nokusebenza kakuhle ngenxa yokusebenza kakuhle kwemitha kunye nokuyilwa kwazo.
