4 × 4 Butler matrix Ldc-0.5 / 7-18-180s-4x4

I-4 × 4 Butler matrix Ldc-0.5 / 7-180s inethiwekhi ye-beangforming esetshenziswayo esetshenziswa kabanzi ezinhlelweni ze-antenna ukufezekisa ukulawulwa kokuqondisa okuqondile. Ithola amandla okusebenza okuphezulu komholi-MW-degree kanye ne-180-degree couplers, okuyizakhi ezibucayi eziqinisekisa ukunemba kwesigaba esikhethekile, ukungalingani okungafani nokungalingani okuvelele, nokuphindwaphindwa okuvelelayo. Lawa ma-couplers aklanyelwe ukuhlukanisa futhi ahlanganise amasiginali ngokuthembekile okuphezulu, okwenza ubuqili be-butler matrix ukukhiqiza imishayo eminingi ngokusebenza okungaguquki kulo lonke uhla lwemvamisa ebanzi.

Ukucushwa okungu-4 × 4 kuxhasa okokufaka okune namachweba okukhipha amane, okwenza kube kuhle ngezicelo ezifana nezinhlelo zokuhlelwa kwezigaba, izinhlelo zokuxhumana ezingenantambo, nezinhlelo ze-radar. Amandla awo okudala ama-orthogonal beams avumela ukufakwa kwesiginali okuthuthukile kanye nokuncishiswa kokuphazanyiswa, ethuthukisa ukusebenza kahle kohlelo. Ukusetshenziswa kwama-coupler we-hybrid abaholi-MW kuqinisekisa ukuthi i-matrix igcina ukulahleka kokufaka okuphansi kanye nokuhlukaniswa okuphezulu, okubalulekile ukuze kugcinwe ukuthembeka kwesiginali ezindaweni eziyinkimbinkimbi ze-multing beam ezindaweni eziyinkimbinkimbi ezinamabala amaningi.

Ngomklamo wayo onamandla kanye nokusebenza okuphezulu, i-4 × 4 butler matrix Ldc-0.5 / 7-180s yisisombululo esithembekile sezinhlelo ezisezingeni eliphakeme ze-RF nezinhlelo zeMicrowave, zivumelanisa ubuchwepheshe bokuxhumana kwanamuhla. Inhlanganisela yayo yokunemba, ukuqina, nokuphindaphinda kwenza kube yinto ekhethwayo yonjiniyela abafuna izixazululo zokusebenza okuphezulu.
