I-ANT051 I-Antenna Array Yezinto Ezine Ezijikelezayo
| Umholi-mw | Isingeniso ku-Four Element Spiral Antenna Array |
Sethula ubuchwepheshe be-microwave bomholi (leader-mw) obusha bamuva kubuchwepheshe be-antenna - ama-stereo e-antenna e-helical amaningi aqinile. Le array esezingeni eliphezulu iklanyelwe ukuguqula indlela esibona futhi sisebenzisa ngayo izinhlelo ze-antenna, iletha ukusebenza okungenakuqhathaniswa kanye nokuguquguquka ngendlela eklanywe kahle neyinkimbinkimbi.
Inhliziyo yalolu hlu oluguquguqukayo yi-element ye-antenna eyisiyingi, ehlanganiswe ngokucophelela esakhiweni seplatifomu esinciphile. Isakhiwo sakhiwe indawo ephezulu kanye nezinhlangothi eziningi, ngayinye exhunywe emaphethelweni ongaphezulu. Izinhlangothi zezinhlangothi eziseduze nazo zixhumene, okudala iplatifomu engenamthungo neqinile yezingxenye ze-antenna.
Umklamo oyingqayizivele wesakhiwo sepulatifomu esithambile uvumela izakhi ze-antenna ezilengayo ukuthi zibekwe phezulu nasemaceleni, okwandisa ukumbozwa kwe-array kanye nokusebenza kwayo. Lokhu kulungiselelwa kwenza i-array ikwazi ukukhipha imisebe eminingi ngendlela ye-stereoscopic, ngaleyo ndlela ithuthukise amakhono okwamukela nokudlulisa uhlelo lwe-antenna.
Esinye sezici ezibalulekile zesakhiwo sepulatifomu esinciphile ukuma okuvamile kwe-polygonal kwendawo ephezulu, okuthuthukisa kakhulu ukusatshalaliswa okufanayo kwezinto ze-antenna futhi kwenze ngcono ukusebenza kwe-array. Lokhu kuqinisekisa ukuthi i-array ingaletha amandla esignali ahambisanayo nathembekile kuzo zonke izinhlelo zokusebenza nezindawo ezahlukahlukene.
