Zibukeka njani iiAntennas ezichasene nokuxinana?
Uluhlu i-antennaEzi zixhobo zisetyenziswa kwizicelo zokulwa nokuphazamiseka zifumene ingqwalasela ebanzi kushishino ngenxa yokukwazi kwazo ukunciphisa imiphumo yokuphazamiseka nokuphucula ukwamkelwa kwemiqondiso. Ngenxa yemfuno ekhulayo yeenkqubo zonxibelelwano ezithembekileyo nezisebenza kakuhle kumacandelo ahlukeneyo afana nonxibelelwano, i-aerospace, ukhuselo kunye neemoto, umkhwa wokusebenzisa ii-antennas ezidibeneyo ukuzikhusela kokuphazamiseka uye wanda.
Eli shishini linomdla ngakumbi kwii-antennas ezidibeneyo ezinokucinezela ngempumelelo imithombo eyahlukeneyo yokuphazamiseka efana nokuphazamiseka kwe-co-channel, ukuphazamiseka kwe-adjacent-channel kunye nezibonakaliso zokuphazamiseka ezenziweyo. Olu hlobo luqhutywa yimfuno yeenkqubo zonxibelelwano eziqinileyo ezikwaziyo ukusebenza kwiindawo ezixineneyo nezinengxolo ze-electromagnetic.
Njengoko imfuno yeenkqubo zonxibelelwano ezingenazingcingo ezingenazingcingo isanda, kulindeleke ukuba ii-antenna ze-array zezicelo ezichasene nokuphazamiseka ziqhubeke nokukhula ngokuthandwa. Njengoko itekhnoloji engenazingcingo ithandwa ngakumbi kwaye iinethiwekhi ze-5G zisetyenziswa, imfuneko yezisombululo eziphambili zokulwa nokuphazamiseka iya kubonakala ngakumbi, nto leyo eqhubela phambili ukwamkelwa kwee-antenna ze-array kushishino.
Ukuya phambili, uphuhliso lwee-antenna ze-array ezinezakhono eziphambili zokucubungula isignali, iteknoloji yokuguqula i-beamforming, kunye nobuchule be-cognitive radio kulindeleke ukuba ibe yindawo ephambili ekugxilwe kuyo. Olu phuculo luya kwenza ii-antenna ze-array zikwazi ukuziqhelanisa neemeko zokuphazamiseka ezitshintshayo, ziphucule ukusebenza kakuhle kwe-spectral kwaye ziphucule ukusebenza kwenkqubo iyonke.
Ukongeza, ukudibanisa ubukrelekrele bokwenziwa kunye ne-algorithms yokufunda koomatshini kwiinkqubo ze-antenna ezidibeneyo kulindeleke ukuba kuguqule amandla okulwa nokuphazamiseka, okuvumela ukubonwa, ukuhlelwa kunye nokunciphisa ukuphazamiseka ngexesha langempela. Olu dibaniso luya kuvula indlela ye-antenna ezizimeleyo nezizilungelelanisayo ezinokulwa ngempumelelo nokuphazamiseka kwiindawo ezintsonkothileyo nezitshintshayo.
Ngamafutshane, ngenxa yesidingo seenkqubo zonxibelelwano eziqinileyo nezithembekileyo, eli shishini linomdla ngakumbi kwii-antenna ze-array zezicelo zokulwa nokudibanisa. Uphuhliso lwexesha elizayo lwee-antenna ze-array luza kugxila ekuqhubekeni kwe-signal processing, i-adaptive beamforming, i-cognitive radio kunye nokuhlanganiswa kobukrelekrele bokwenziwa, nto leyo eza kudala indlela yetekhnoloji yokulwa nokuphazamiseka kwiminyaka embalwa ezayo.
