QHAGAMSHELANA NGOKU

I-dual directional loop coupler sisixhobo esidityanisiweyo se-microwave esenza ukuba ugqithiso olusebenzayo kunye nokudibanisa imiqondiso kwiindlela zamaza ezahlukeneyo.

Ngokukodwa, i-microwave i-dual directional loop coupler yenziwe yi-waveguide ejikelezayo kunye namaza amaninzi adibeneyo. Ngokulungelelanisa amandla okudibanisa phakathi kokudibanisa .
I-Waveguide kunye ne-loop waveguide, ukuhanjiswa kwesalathiso samandla phakathi kwee-waveguides ezahlukeneyo kunokufezekiswa. Inxalenye ephambili ye-coupler ye-directional loop yibhloko ye-dielectric ejikelezayo, ngokuqhelekileyo ihlanganiswe ne-tubular okanye i-sheet-like block, kunye nomgca we-microstrip ojikelezayo ngaphakathi kwebhloko. Xa isignali ye-high-frequency ingena kwibhloko ye-dielectric annular ukusuka kwelinye lamachweba, iya kuhamba ngokuthe ngcembe kwindlela ejikelezayo ngexesha elifutshane kwaye ekugqibeleni isasazwe kwamanye amachweba. Ngethuba lenkqubo yokudlulisa, ngenxa yeempawu ze-resonance yebhloko ye-dielectric kunye nendlela emiselweyo yesekethe, ukuhlukana kwesigaba sokutshintsha kugcinwe kwii-degrees ze-90, ukufezekisa ukuhanjiswa kwamandla ngokuchanekileyo.

Isicelo:

Ii-couplers ze-loop eziphindwe kabini zisetyenziswa ngokubanzi kunxibelelwano lwe-microwave, iinkqubo ze-radar, unxibelelwano lwesathelayithi, ii-antenna arrays, kunye namanye amacandelo. Phakathi kwabo, isicelo kwiinkqubo zonxibelelwano ezingenazintambo zibanzi ngokukodwa, njenge-3G, i-4G, i-5G inethiwekhi yonxibelelwano lweselula kunye neenethiwekhi ze-WLAN, kunye nokufunyanwa kwe-radar kunye nokusasazwa kwethelevishini.

Iimpawu:

Xa kuthelekiswa nee-couplers zesiqhelo ze-180 degree, i-broadband ephindwe kabini eyalathisa loop coupler ineengenelo ezinje nge-bandwidth ebanzi, ilahleko esezantsi, umthamo omncinci kunye nobunzima, kunye nokwenza lula kunye nokudityaniswa. Ukungalungi kukuba ulawulo oluchanekileyo oluphezulu luyafuneka ngexesha lenkqubo yokuvelisa, kwaye kunokubakho nemiba efana nokungalingani kwesigaba kunye nokuguquguquka kwamandla ngexesha lokusebenza. Ngoko ke, ukuyila okukhethekileyo kunye namanyathelo afunekayo ukulungiswa kunye nembuyekezo.

Qualwaveibonelela nge-broadband kunye namandla aphezulu adibanisa i-loop loop couplers kuluhlu olubanzi ukusuka kwi-1.72 ukuya kwi-18GHz. I-couplers isetyenziswa ngokubanzi kwizicelo ezininzi.
