A Butler matrix imhando yebeamforming network inoshandiswa mune antenna arrays uye phased array system.Mabasa ayo makuru ndeaya:
● Beam steering - Inogona kutungamira danda reantenna kumakona akasiyana nekuchinja chiteshi chekuisa.Izvi zvinobvumira iyo antenna system kuti itarise nemagetsi danda rayo pasina kufambisa antennas.
● Multi-beam formation - Inogona kudyisa antenna array nenzira inobudisa matanda akawanda panguva imwe chete, imwe neimwe inotarisa kune imwe nzira.Izvi zvinowedzera kuvhara uye kunzwa.
● Beam kupatsanurwa - Inopatsanura chiratidzo chekuisa muhuwandu hwekubuda kwechiteshi nehukama hwechikamu.Izvi zvinogonesa iyo yakabatana antenna array kuti igadzire matanda ekuraira.
● Beam combining - Basa rinopindirana rekutsemura danda.Iyo inosanganisa masaini kubva kune akawanda antenna zvinhu kuita imwechete inobuda ine yakakwirira pfuma.
Iyo Butler matrix inozadzisa mabasa aya kuburikidza nechimiro chayo chehybrid couplers uye yakagadziriswa phase shifters yakarongwa mune matrix marongerwo.Zvimwe zvakakosha zvivakwa:
● The phase shift between adjacent output ports inowanzoita 90 degrees (quarter wavelength).
● Nhamba yemapuranga inogumira nehuwandu hwezvikepe (N x N Butler matrix inobudisa N matanda).
● Beam mirayiridzo inotarirwa nematrix geometry uye phasing.
● Kurasikirwa kwakaderera, kungoita, uye kushandiswa kwekudzorera.
Saka muchidimbu, basa guru reButler matrix ndere kudyisa antenna array nenzira inobvumira dynamic beamforming, danda kutungamira, uye akawanda-beam kugona kuburikidza nemagetsi kutonga pasina zvikamu zvinofamba.Iyo tekinoroji inogonesa yemagetsi scanned arrays uye akaganhurwa array radar.
Concept Microwave mutengesi wepasirese webutler matrix, inotsigira multichannel MIMO kuyedzwa kweanosvika 8 + 8 antenna ports, pamusoro pehombe frequency renji.
