I-antenna ye-Microstripwuhlobo olusha lwe-microwaveuthiesebenzisa ama-conductive strips aphrintwe ku-dielectric substrate njengeyunithi ekhipha imisebe ye-antenna. Ama-antenna e-Microstrip asetshenziswe kabanzi ezinhlelweni zokuxhumana zesimanje ngenxa yobukhulu bawo obuncane, isisindo esilula, iphrofayili ephansi, nokuhlanganiswa okulula.
Isebenza kanjani i-antenna ye-microstrip
Umgomo wokusebenza we-antenna ye-microstrip usekelwe ekudluliselweni nasemisebeni yamagagasi kagesi. Ngokuvamile iqukethe i-radiation patch, i-dielectric substrate kanye ne-ground plate. I-patch ye-radiation iphrintiwe ebusweni be-dielectric substrate, kuyilapho i-ground plate itholakala ngakolunye uhlangothi lwe-dielectric substrate.
1. Isiqephu sokukhishwa kwemisebe: I-radiation patch iyingxenye ebalulekile yothi lwe-microstrip. Kuwumugqa wensimbi ozacile onesibopho sokuthwebula nokukhipha imisebe yamagagasi kagesi.
2. I-Dielectric substrate: I-substrate ye-dielectric ngokuvamile yenziwe ngezinto ezilahlekile, ezine-dielectric-constant, njenge-polytetrafluoroethylene (PTFE) noma ezinye izinto zobumba. Umsebenzi wawo ukusekela isiqeshana semisebe futhi sisebenze njengendawo yokusabalalisa amaza kagesi.
3. I-Ground plate: I-ground plate iyisendlalelo esikhulu sensimbi esitholakala ngakolunye uhlangothi lwe-dielectric substrate. Yakha i-capacitive coupling ne-radiation patch futhi ihlinzeka ngokusatshalaliswa kwensimu ye-electromagnetic edingekayo.
Lapho isignali ye-microwave ifakwa ku-antenna ye-microstrip, yenza igagasi elimile phakathi kwe-radiation patch kanye ne-ground plate, okuholela emisebeni yamaza kagesi. Ukusebenza kahle kwemisebe kanye nephethini ye-antenna ye-microstrip kungalungiswa ngokushintsha ukwakheka nosayizi wesichibi kanye nezici ze-dielectric substrate.
I-RFMISOIzincomo zochungechunge lwe-Microstrip Antenna:
I-RM-DAA-4471 (4.4-7.5GHz)
I-RM-MPA1725-9 (1.7-2.5GHz)

Umehluko phakathi kwe-microstrip antenna kanye ne-patch antenna
I-patch antenna iwuhlobo lwe-microstrip antenna, kodwa kunomehluko othile ngesakhiwo kanye nesimiso sokusebenza phakathi kwalokhu kokubili:
1. Umehluko wesakhiwo:
I-Microstrip antenna: imvamisa iqukethe i-radiation patch, i-dielectric substrate kanye ne-ground plate. I-patch imisiwe ku-substrate ye-dielectric.
I-patch antenna: Ingxenye ekhipha imisebe ye-patch antenna ixhunywe ngokuqondile ku-dielectric substrate, imvamisa ngaphandle kwesakhiwo esimisiwe esisobala.
2. Indlela yokondla:
I-Microstrip antenna: Okuphakelayo kuvame ukuxhunywa esiqeshini esikhipha imisebe ngokusebenzisa ama-probe noma imigqa ye-microstrip.
I-patch antenna: Izindlela zokuphakela zihluke kakhulu, okungaba ukuphakela onqenqemeni, ukuphakelwa kwe-slot noma ukuphakela nge-coplanar, njll.
3. Ukusebenza kahle kwemisebe:
I-Microstrip antenna: Njengoba kunegebe elithile phakathi kwe-patch ye-radiation kanye ne-ground plate, kungase kube nenani elithile lokulahlekelwa kwegebe lomoya, elithinta ukusebenza kahle kwemisebe.
I-patch antenna: Into ekhipha imisebe ye-patch antenna ihlanganiswe eduze ne-dielectric substrate, evame ukuba nokusebenza kahle kwemisebe ephezulu.
4. Ukusebenza komkhawulokudonsa:
I-Microstrip antenna: Umkhawulokudonsa umncane kakhulu, futhi umkhawulokudonsa udinga ukwenyuswa ngomklamo owenziwe kahle.
I-patch antenna: Umkhawulokudonsa obanzi ungafinyelelwa ngokuklama izakhiwo ezihlukahlukene, njengokwengeza izimbambo ze-radar noma ukusebenzisa izakhiwo ezinezendlalelo eziningi.
5. Izikhathi zokufaka isicelo:
I-Microstrip antenna: ifanele izinhlelo zokusebenza ezinezidingo eziqinile ekuphakameni kwephrofayela, njengokuxhumana ngesathelayithi nokuxhumana kweselula.
Ama-patch antenna: Ngenxa yokuhlukahluka kwesakhiwo, angasetshenziswa kuhlelo olubanzi lwezinhlelo zokusebenza, okuhlanganisa i-radar, ama-LAN angenawaya, nezinhlelo zokuxhumana zomuntu siqu.
Ekuphetheni
Ama-antenna ama-Microstrip nama-patch antenna womabili ama-microwave antenna asetshenziswa kakhulu ezinhlelweni zokuxhumana zesimanje, futhi anezici zawo kanye nezinzuzo zawo. Ama-antenna e-Microstrip ahamba phambili ezinhlelweni ezivinjelwe isikhala ngenxa yephrofayili yazo ephansi nokuhlanganiswa okulula. Ngakolunye uhlangothi, ama-patch antenna avame kakhulu ezinhlelweni ezidinga umkhawulokudonsa obanzi kanye nokusebenza kahle okuphezulu ngenxa yokusebenza kahle kwawo okuphezulu kwemisebe nokuklama kwawo.
