ANT051 Isine Element Spiral Antenna Array
| Inkokeli-mw | Intshayelelo kwiSine Element Spiral Antenna Array |
Ukwazisa iNkokheli ye-microwave tech.,(inkokeli-mw) into entsha yamva nje kubuchwephesha be-eriyali - i-eriyali esisigxina enemiqadi emininzi yoluhlu lwestereo. Olu luhlu lwe-edge lwenzelwe ukuguqula indlela esibona ngayo kwaye sisebenzise iinkqubo ze-eriyali, ukuhambisa ukusebenza okungenakulinganiswa kunye nokuguquguquka kuyilo oluhlangeneyo nolusebenzayo.
Intliziyo yolu luhlu lwenguquko yi-helical antenna element, edityaniswe ngononophelo kwisakhiwo seqonga le-tapered. Isakhiwo siquka indawo ephezulu kunye namacala amaninzi, ngalinye lidityaniswe kumda wendawo ephezulu. Amacala emacaleni akufutshane nawo aqhagamshelwe, okwenza iqonga elingenamthungo nelomeleleyo lezinto ze-eriyali.
Uyilo olukhethekileyo lwesakhiwo seqonga le-tapered livumela izinto ze-antenna ze-helical ukuba zibekwe phezulu kunye namacala, ukwandisa ukugubungela uluhlu kunye nokusebenza. Olu lungelelwaniso lwenza ukuba uluhlu lukhuphe imiqadi emininzi ngendlela yestereoscopic, ngaloo ndlela iphucula amandla okwamkela kunye nokuhanjiswa kwenkqubo ye-eriyali.
Enye yeempawu eziphambili zesakhiwo seqonga le-tapered yimilo yepolygonal eqhelekileyo yomphezulu ongaphezulu, ophucula ngakumbi ukuhanjiswa okufanayo kwezinto ze-antenna kunye nokwandisa ukusebenza ngokubanzi koluhlu. Oku kuqinisekisa ukuba uluhlu luyakwazi ukuhambisa amandla omqondiso angaguqukiyo kunye nokuthembeka kuzo zonke iintlobo zezicelo kunye nokusingqongileyo.
