Butler Matrix

Butler matrix ndi mtundu wa netiweki yopangira beamforming yomwe imagwiritsidwa ntchito mu ma antenna arrays ndi ma phased array systems. Ntchito zake zazikulu ndi izi:

● Kuwongolera kwa denga - Kumatha kuwongolera denga la antenna ku ngodya zosiyanasiyana mwa kusintha doko lolowera. Izi zimathandiza makina a antenna kuti azitha kujambula denga lake popanda kusuntha ma antenna.
● Kupanga kwa mipiringidzo yambiri - Imatha kudyetsa gulu la ma antenna m'njira yomwe imapanga mipiringidzo yambiri nthawi imodzi, iliyonse ikuloza mbali ina. Izi zimawonjezera kuphimba ndi kukhudzidwa.
● Kugawanika kwa denga - Kumagawa chizindikiro cholowera m'madoko angapo otulutsa omwe ali ndi ubale wapadera wa magawo. Izi zimathandiza kuti gulu la antenna lolumikizidwa lipange mayendedwe owongolera.
● Kuphatikiza kwa denga - Ntchito yogawana denga. Imaphatikiza zizindikiro kuchokera ku zinthu zingapo za antenna kukhala chinthu chimodzi chomwe chimapangitsa kuti pakhale phindu lalikulu.

Matrix ya Butler imakwaniritsa ntchito izi kudzera mu kapangidwe kake ka ma hybrid couplers ndi ma fixed phase shifters omwe amakonzedwa mu matrix layout. Makhalidwe ena ofunikira:

● Kusintha kwa gawo pakati pa madoko otulutsa omwe ali pafupi nthawi zambiri kumakhala madigiri 90 (kotala la kutalika kwa mafunde).
● Chiwerengero cha matabwa chimachepetsedwa ndi chiwerengero cha madoko (N x N Butler matrix imapanga matabwa a N).
● Malangizo a mtanda amatsimikiziridwa ndi matrix geometry ndi phasing.
● Kutayika kochepa, kungokhala chete, komanso kugwira ntchito mobwezerana.

Mwachidule, ntchito yaikulu ya Butler matrix ndikudyetsa gulu la antenna m'njira yomwe imalola mphamvu ya beamforming, beam steering, ndi multi-beam kudzera mu electronic control popanda ziwalo zosuntha. Ndi ukadaulo wothandiza wa ma electronically scanned arrays ndi ma phased array radar.

Concept Microwave ndi kampani yogulitsa matrix padziko lonse lapansi, yomwe imathandizira kuyesa kwa MIMO kwa njira zambiri zama antenna mpaka ma 8+8, pamlingo waukulu.
