I-antenna ye-Microstripuhlobo olusha lwe-microwavei-antennaesebenzisa imichilo yokuhambisa ephrintiwe ku-substrate ye-dielectric njengeyunithi yokukhanyisa i-antenna. Ama-antenna e-Microstrip asetshenziswe kabanzi ezinhlelweni zokuxhumana zanamuhla ngenxa yobukhulu bawo obuncane, isisindo esilula, iphrofayili ephansi, kanye nokuhlanganiswa okulula.
Indlela i-antenna ye-microstrip esebenza ngayo
Umgomo wokusebenza we-microstrip antenna usekelwe ekudlulisweni kanye nemisebe yamagagasi kagesi. Ngokuvamile iqukethe i-radiation patch, i-dielectric substrate kanye ne-ground plate. I-radiation patch iphrintiwe ebusweni be-dielectric substrate, kuyilapho i-ground plate itholakala kolunye uhlangothi lwe-dielectric substrate.
1. I-Radiation patch: I-radiation patch iyingxenye ebalulekile ye-antenna ye-microstrip. Iwumugqa omncane wensimbi obhekene nokubamba nokukhipha amaza kagesi.
2. I-substrate ye-dielectric: I-substrate ye-dielectric ivame ukwenziwa ngezinto ezilahlekelwa kancane, ezihlala njalo nge-dielectric, njenge-polytetrafluoroethylene (PTFE) noma ezinye izinto ze-ceramic. Umsebenzi wayo ukusekela i-radiation patch futhi isebenze njengendawo yokusabalala kwamagagasi kagesi.
3. Ipuleti lomhlabathi: Ipuleti lomhlabathi liyingqimba enkulu yensimbi etholakala kolunye uhlangothi lwe-dielectric substrate. Lakha ukuxhumanisa okunamandla ne-radiation patch futhi linikeza ukusatshalaliswa kwensimu kagesi okudingekayo.
Uma isignali ye-microwave ifakwa ku-antenna ye-microstrip, yakha igagasi elima phakathi kwe-patch yemisebe kanye ne-ground plate, okuholela emisebeni yamagagasi kagesi. Ukusebenza kahle kwemisebe kanye nephethini ye-antenna ye-microstrip kungalungiswa ngokushintsha ukuma nosayizi we-patch kanye nezici ze-substrate ye-dielectric.

Umehluko phakathi kwe-antenna ye-microstrip kanye ne-antenna ye-patch
I-antenna ye-patch iwuhlobo lwe-antenna ye-microstrip, kodwa kukhona umehluko othile ngesakhiwo kanye nesimiso sokusebenza phakathi kwalokhu okubili:
1. Umehluko wesakhiwo:
I-antenna ye-Microstrip: ngokuvamile iqukethe i-patch yemisebe, i-substrate ye-dielectric kanye ne-ground plate. I-patch ilenga ku-substrate ye-dielectric.
I-antenna ye-patch: Ingxenye ekhipha imisebe ye-antenna ye-patch inamathele ngqo kwi-substrate ye-dielectric, ngokuvamile ayinaso isakhiwo esimisiwe esisobala.
2. Indlela yokondla:
I-antenna ye-Microstrip: I-feed ivame ukuxhunywa ku-patch ekhipha imisebe ngama-probe noma imigqa ye-microstrip.
I-antenna ye-Patch: Izindlela zokudla zihlukahlukene kakhulu, okungaba ukudla okusemaphethelweni, ukudla kwe-slot noma ukudla kwe-coplanar, njll.
3. Ukusebenza kahle kwemisebe:
I-antenna ye-Microstrip: Njengoba kukhona igebe elithile phakathi kwe-patch yemisebe ne-ground plate, kungase kube nokulahleka kwegebe lomoya elithile, okuthinta ukusebenza kahle kwemisebe.
I-antenna ye-patch: Ingxenye ekhipha imisebe ye-antenna ye-patch ihlanganiswe eduze ne-substrate ye-dielectric, evame ukuba nokusebenza kahle kwemisebe okuphezulu.
4. Ukusebenza komkhawulokudonsa:
I-antenna ye-Microstrip: I-bandwidth incane kakhulu, futhi i-bandwidth idinga ukwandiswa ngokuklama okuhle.
I-antenna ye-Patch: I-bandwidth ebanzi ingatholakala ngokuklama izakhiwo ezahlukahlukene, njengokwengeza izimbambo ze-radar noma ukusebenzisa izakhiwo ezinezingqimba eziningi.
5. Izikhathi zokufaka isicelo:
I-antenna ye-Microstrip: ifanele izinhlelo zokusebenza ezinezidingo eziqinile zokuphakama kwephrofayili, njengokuxhumana ngesathelayithi kanye nokuxhumana ngeselula.
Ama-antenna e-Patch: Ngenxa yokwahlukahluka kwawo kwesakhiwo, angasetshenziswa ezinhlobonhlobo zezinhlelo zokusebenza, kufaka phakathi i-radar, ama-LAN angenantambo, kanye nezinhlelo zokuxhumana zomuntu siqu.
Ekuphetheni
Ama-antenna e-Microstrip kanye nama-antenna e-patch womabili ama-antenna e-microwave asetshenziswa kakhulu ezinhlelweni zokuxhumana zesimanje, futhi anezici zawo nezinzuzo zawo. Ama-antenna e-Microstrip ahamba phambili ezinhlelweni zokusebenza ezivinjiwe isikhala ngenxa yesimo sawo esiphansi kanye nokuhlanganiswa okulula. Ama-antenna e-patch, ngakolunye uhlangothi, avame kakhulu ezinhlelweni zokusebenza ezidinga i-bandwidth ebanzi kanye nokusebenza kahle okuphezulu ngenxa yokusebenza kahle kwemisebe ephezulu kanye nokuklanywa kwawo.
Ukuze ufunde kabanzi ngama-antenna, sicela uvakashele:
