Pfungwa yeantenna dze arrayYakatanga kutangira kuma1930 uye pakutanga yaiumbwa nezvinhu zvakawanda zveantenna kuti ivandudze mashandiro ekutaurirana uye radar systems. Nekufambira mberi kwetekinoroji, array antennas dzakakura zvishoma nezvishoma kuita masisitimu ese akagadzirwa nehuwandu hwakawanda hwe antenna elements, izvo zvinogona kuita kuti zviratidzo zvive zvakaoma uye kugadzira beam. Muma1950, array antennas dzakatanga kushandiswa zvakanyanya muminda yemauto neyendege. Mushure mezvo, nekuvandudzwa kwetekinoroji ye microwave nekutaurirana, array antennas dzakashandiswa muminda yakaita se satellite communications, radar, mobile communications uye wireless networks.
Musimboti wekushanda
Antena yeArray isystem yeantenna ine zvinhu zvakawanda zveantenna zvakarongwa nenzira yakatarwa uye nzvimbo. Nheyo yekushanda kwemaantena eArray yakavakirwa papfungwa dzekugadzira beam uye kunanga beam.
Kana wave yechiitiko yasvika pa antenna ye array, chinhu chega chega che antenna chinogamuchira wave yechiitiko yakafanana ine kunonoka kwakasiyana kwechikamu. Kunonoka kwechikamu pakati pezvinhu izvi zve antenna kunowanikwa nekugadzirisa mitsetse yekunonoka kana ma phase shifters mudunhu. Nekugadzirisa kunonoka kwechikamu chechinhu chega chega che antenna, kugadzirwa uye kupindira kwema wave echiitiko mu array kunogona kudzorwa.
Kuburikidza nekudzora kunonoka kwechikamu, ma antenna e array anogona kugadzira danda. Danda rinoreva divi guru resimba rinoburitswa ne antenna, rakafanana nedanda rakasimba rechiedza kana danda reruzha rakanongedzwa munzira yakati. Nekugadzirisa kunonoka kwechikamu chega chega che antenna, mafungu anouya anogona kuiswa pamusoro uye kuwedzerwa mune dzimwe nzira uye kudzimwa uye kudzikiswa mune dzimwe nzira. Nenzira iyi, antenna ye array inogona kugadzira danda rakatetepa uye rakanangana, nokudaro zvichiwedzera kuwana nekutungamira kwe antenna system.
Kutungamira kwe antenna ye array kunogona kugadziriswa nekuchinja kunonoka kwe phase. Nekudzora kunonoka kwe phase, kona yekunongedzera ye beam inogona kuchinjwa kuti iendeswe kune chinangwa kana nzvimbo yaunoda. Izvi zvinoita kuti antenna dze array dzive nemashandisirwo akakosha muma radar system, communication systems uye wireless networks, uye dzinogona kuita mabasa akadai sekutevera chinangwa, signal direction uye interference cancel.
Pamusoro pekugadzira beamforming nekutungamira, ma array antenna ane zvimwe zvakanakira, zvakaita se spatial multiplexing, anti-interference capabilities, uye flexibility. Nekushandisa kudyidzana kuripo pakati pezvinhu zve antenna mu array, masaini akawanda anogona kugamuchirwa nekutumirwa panguva imwe chete, nokudaro zvichiwedzera kugona kwesystem uye kushanda zvakanaka.
Muchidimbu, ma antenna e array anowana beamforming uye directionivity nekugadzirisa phase delayer yechinhu chega chega che antenna kuti awane radiation yakawedzerwa uye kugamuchira munzira dzakatarwa. Ane mashandisirwo akasiyana-siyana mukutaurirana, radar uye wireless networks, zvichipa zvakanakira zvakaita se high gain, directionivity uye flexibility.
