I-ANT051 yeZinto ezine ezijikelezayo ze-Antenna Array
| Inkokeli-mw | Intshayelelo kwi-Four Element Spiral Antenna Array |
Ukwazisa ubuchwepheshe be-microwave yeNkokeli. (leader-mw) obutsha bamva nje kwitekhnoloji ye-antenna - ii-antenna stereo arrays ezizinzileyo ezineemitha ezininzi ze-helical. Olu luhlu oluphambili lwenzelwe ukuguqula indlela esizibona kwaye sizisebenzisa ngayo iinkqubo ze-antenna, zibonelela ngokusebenza okungenakuthelekiswa nanto kunye nokuguquguquka kuyilo oluncinci nolusebenzayo.
Intliziyo yale array iguqukayo yi-antenna element ye-helical, edityaniswe ngononophelo kwisakhiwo seqonga elinciphileyo. Isakhiwo siqulathe umphezulu ophezulu kunye namacala amaninzi, ngalinye liqhagamshelwe kumphetho womphezulu ophezulu. Amacala amacala akufutshane nawo adibene, okwenza iqonga elingenamthungo neliqinileyo lezinto ze-antenna.
Uyilo olulodwa lwesakhiwo seqonga elithambileyo luvumela izinto ze-antenna ezijikelezayo ukuba zibekwe phezulu nasemacaleni, nto leyo eyenza ukuba i-array ikwazi ukugubungela kakuhle kunye nokusebenza kakuhle. Olu lungiselelo lwenza ukuba i-array ikhuphe imisebe emininzi ngendlela ye-stereoscopic, ngaloo ndlela iphucula amandla okwamkela kunye nokudlulisa inkqubo ye-antenna.
Enye yezona zinto zibalulekileyo zesakhiwo seqonga elithambileyo yimilo eqhelekileyo ye-polygonal yomphezulu ophezulu, nto leyo ephucula ngakumbi ukusasazwa okufanayo kwezinto ze-antenna kwaye iphucule ukusebenza kwe-array iyonke. Oku kuqinisekisa ukuba i-array inokubonelela ngamandla esignali ahambelanayo nathembekileyo kuzo zonke iintlobo zezicelo kunye neendawo.
