I-Antennas idlala indima ebalulekile enqubweni yezimpawu zokuxhumana ezingenantambo, ezisebenza njengendlela yokuhambisa imininingwane nge-Space. Ikhwalithi nokusebenza kwezimpondo zibumba ngqo ikhwalithi nokusebenza kahle kwezokuxhumana okungenantambo. Ukufana kwe-Imperance kuyisinyathelo esibalulekile ekuqinisekiseni ukusebenza okuhle kokuxhumana. Ngokwengeziwe, izimpondo zingabonakala njengohlobo lwenzwa, ngokusebenza ngaphandle kokuthola nokudlulisa amasiginali. Ama-antenna akwazi ukuguqula amandla kagesi abe amasiginali wokuxhumana angenantambo, ngaleyo ndlela afinyelele umbono wamagagasi ama-electromagnetic kanye namasiginali endaweni ezungezile. Ngakho-ke, umklamo we-antenna nokwenza kahle kuhlobene nokwenziwa kuphela ekusebenzeni kwezinhlelo zokuxhumana, kepha nasekwazi ukukwazi ukubona izinguquko endaweni ekhona. Ensimini ye-elekthronikhi yezokuxhumana, ukuze uzuze ngokuphelele iqhaza le-antennas, onjiniyela basebenzisa amasu ahlukahlukene wokufanisa ukuqhathanisa ukuqinisekisa ukusebenzisana okusebenzayo phakathi kwe-antenna nohlelo lwesekethe elizungezile. Izindlela ezinjalo zezobuchwepheshe zihlose ukwenza ngcono ukusebenza kahle kokudluliselwa kwesiginali, ukunciphisa ukulahleka kwamandla, kanye nokuqinisekisa ukusebenza okuhle kwamabanga ajwayelekile ahlukahlukene. Njengoba kunje, izimpondo ziyinto esemqoka ezinhlelweni zokuxhumana ezingenantambo, futhi zidlala indima ebalulekile njengezinzwa zokubona nokuguqula amandla kagesi.
** Umqondo wokufanisa i-antenna **
Ukufana kwe-Antenna Impodance kuyinqubo yokuxhumanisa i-antenance ye-antenna ngokukhishwa komthombo wesiginali noma ukuvinjwa kokufakwa kwensiza etholakalayo, ukuze kufinyelelwe isimo sokudluliswa esiphezulu sesiginali. Ukuze udlulise ukuhambisa ama-antennas, ama-mismatches okususa kungaholela ekunciphiseni amandla, anciphise ibanga lokuhambisa, kanye nomonakalo ongaba khona ezingxenyeni ze-antenna. Okokuthola izimpondo, ama-mismatches okulimazeka azoholela ekunciphiseni ukuzwela, ukwethulwa kokuphazanyiswa komsindo, kanye nomthelela kwikhwalithi yesiginali etholakele.
** Indlela Yokuhambisa Indlela: **
Isimiso: Sebenzisa i-Transfer Line theory ukufezekisa ukufana ngokushintsha isimo sokuvikelwa komugqa wokuhambisa.
Ukuqaliswa: Kusetshenziswa imigqa yokudlulisela, abaguqukayo nezinye izinto.
Ububi: Inani elikhulu lezakhi zandisa ubunzima obuyinkimbinkimbi kanye nokusetshenziswa kwamandla.
** Indlela yokuhlanganisa i-capacition: **
Isimiso: Ukuqhathaniswa kwe-Imperance phakathi kwe-antenna ne-Signal Source / Idivaysi yokuthola itholakala nge-capacitor yochungechunge.
Isikali esisebenzayo: esetshenziselwa imvamisa ephansi kanye ne-antennas ephakeme yemvamisa.
Ukucatshangelwa: Umphumela ofanayo uthonywa ukukhethwa kwe-capacitor, amaza aphezulu angangenisa ukulahleka okwengeziwe.
** Indlela ye-Short-Circuit: **
Isimiso: Ukuxhuma ingxenye yokufushanisa kuze kube sekupheleni kwe-antenna kwakha umdlalo nomhlabathi.
Izici: Elula ukusebenzisana kepha alungele ukuphendula imvamisa, alilungele zonke izinhlobo zokungaziphathi kahle.
** Indlela yeTransformer: **
Isimiso: Ukufanisa ukungcola kwe-antenna nesifunda ngokuguqula ngezilinganiso ezihlukile ze-transformer.
Ukusebenza: ikakhulukazi kufanelekile ama-antenna avamizela aphansi.
Umphumela: Kufezekisa ukufana kwe-Impotance ngenkathi futhi kwandisa ama-amplitude namandla, kepha wethula ukulahleka okuthile.
** I-Chip inductor coupling indlela: **
Isimiso: Izingwegwe ze-chip zisetshenziselwa ukufeza ukuqhathanisa ukuguquguquka kuma-antennas amvamisa, kuyilapho kunciphisa ukuphazanyiswa komsindo.
Isicelo: I-SONnjelwe Ngokuvamile kuzinhlelo zokusebenza zemvamisa ephezulu njenge-RFID.
I-Concept Microwave ngumkhiqizi ochwepheshe wezakhi ze-5G RF zezinhlelo ze-antenna eChina, kufaka phakathi isihlungi se-RF Lowpass, isihlungi se-bandppass, isihlungi se-bandch, i-coupler ephakemeyo. Zonke zingenziwa ngokwezifiso ngokuya ngokwalokho okuvuselelayo kwakho.
