I-ANT051 I-Four Element Spiral Antenna Array
| Umholi-mw | Isingeniso se-Four Element Spiral Antenna Array |
Sethula i-Leader microwave tech.,(umholi-mw) izinto ezintsha zakamuva kubuchwepheshe be-antenna - ama-array e-stereo e-helical egxilile enamapulangwe amaningi. Lolu chungechunge oluphambili luklanyelwe ukuguqula indlela esibona futhi sisebenzise ngayo amasistimu wezimpondo, zilethe ukusebenza okungenakuqhathaniswa nokuguquguquka kumklamo ohlangene futhi ophumelelayo.
Inhliziyo yalolu hlu oluguquguqukayo yi-elementi ye-helical antenna, ehlanganiswe ngokucophelela esakhiweni seplathifomu ecijile. Isakhiwo siqukethe indawo ephezulu kanye nezinhlangothi eziningi, ngayinye exhunywe emaphethelweni angaphezulu. Izinhlangothi zezinhlangothi ezincikene nazo zixhumene, okudala inkundla engenamthungo neqinile yezinto ze-antenna.
Idizayini eyingqayizivele yesakhiwo seplathifomu ecijile ivumela izakhi ze-antenna e-helical ukuthi zibekwe phezulu nasezinhlangothini, okukhuphula ukumbozwa kwamalungu afanayo nokusebenza. Lokhu kulungiselelwa kuvumela amalungu afanayo ukuthi akhiphe imishayo eminingi ngendlela ye-stereoscopic, ngaleyo ndlela kuthuthukisa amandla okwamukela nawokudlulisela esistimu ye-antenna.
Esinye sezici ezibalulekile zesakhiwo seplathifomu ecijile wumumo ojwayelekile we-polygonal wendawo engaphezulu, okuthuthukisa ngokwengeziwe ukusatshalaliswa okufanayo kwama-elementi e-antenna futhi kuthuthukise ukusebenza okuphelele kohlu. Lokhu kuqinisekisa ukuthi amalungu afanayo angaletha amandla esignali angaguquki nathembekile kuzo zonke izinhlelo zokusebenza nezindawo.
