Butler Matrix

I-Butler matrix luhlobo lwenethiwekhi yokwenza imisebe esetyenziswa kwii-antenna arrays nakwiinkqubo ze-phased array. Imisebenzi yayo ephambili yile:

● Ukulawula ngomqadi – Ingalawula umqadi we-antenna kwii-engile ezahlukeneyo ngokutshintsha i-input port. Oku kuvumela inkqubo ye-antenna ukuba iskena umqadi wayo ngombane ngaphandle kokushukumisa ii-antenna ngokwasemzimbeni.
● Ukwakheka kwemisebe emininzi – Ingondla uluhlu lwee-antenna ngendlela evelisa imisebe emininzi ngaxeshanye, nganye ijonge kwicala elahlukileyo. Oku kwandisa ukugquma kunye novakalelo.
● Ukwahlulwa kwemitha – Yahlula isignali yokufaka ibe ziiports ezininzi zokukhupha ezinobudlelwane besigaba esithile. Oku kwenza uluhlu lwe-antenna oludibeneyo lwenze imida yokuqondisa.
● Ukudibanisa imisebe – Umsebenzi wokwahlulahlula imisebe. Idibanisa imiqondiso evela kwizinto ezininzi ze-antenna ibe yimveliso enye enengeniso ephezulu.

I-Butler matrix ifezekisa le misebenzi ngesakhiwo sayo see-hybrid couplers kunye nee-fixed phase shifters ezicwangciswe ngendlela ye-matrix layout. Ezinye zeempawu eziphambili:

● Utshintsho lwesigaba phakathi kwee-output ports ezikufutshane ludla ngokuba ngama-90 degrees (ikota yobude bexesha).
● Inani leemitha lilinganiselwe linani leemitha (i-N x N i-Butler matrix ivelisa iimitha ze-N).
● Izikhokelo zemitha zimiselwa yijiyometri ye-matrix kunye nesigaba.
● Ukulahleka okuphantsi, ukusebenza okungenamsebenzi, kunye nokusebenza ngokulinganayo.

Ngoko ke ngamafutshane, umsebenzi ophambili we-Butler matrix kukunika amandla i-antenna array ngendlela evumela i-dynamic beamforming, i-beam steering, kunye nobuchule be-multi-beam ngokusebenzisa ulawulo lwe-elektroniki ngaphandle kwezinto ezihambayo. Yiteknoloji evumela ii-arrays eziskeniweyo nge-elektroniki kunye nee-radar ze-array eziphasejiweyo.

I-Concept Microwave ngumthengisi wehlabathi jikelele we-butler matrix, exhasa uvavanyo lwe-MIMO yeendlela ezininzi ukuya kuthi ga kwii-antenna ports eziyi-8+8, kuluhlu olukhulu lwamaza.
