ANT051 Four Element Spiral Antenna Array
| Mtsogoleri-mw | Chiyambi cha Four Element Spiral Antenna Array |
Tikubweretsa ukadaulo waposachedwa wa microwave wa Leader., (leader-mw) muukadaulo wa antenna - ma stereo a antenna a helical okhala ndi mipata yambiri. Mndandanda wamakono uwu wapangidwa kuti usinthe momwe timaonera ndikugwiritsa ntchito makina a antenna, kupereka magwiridwe antchito osayerekezeka komanso kusinthasintha kwa kapangidwe kakang'ono komanso kogwira mtima.
Mtima wa gulu losinthali ndi chinthu cha antenna chozungulira, chomwe chimaphatikizidwa mosamala mu kapangidwe ka nsanja yocheperako. Kapangidwe kake kali ndi pamwamba ndi mbali zingapo, zomwe chilichonse chimalumikizidwa m'mphepete mwa pamwamba. Mbali za mbali zoyandikana nazo zimalumikizananso, zomwe zimapangitsa nsanja yolimba komanso yopanda msoko ya zinthu za antenna.
Kapangidwe kapadera ka kapangidwe ka nsanja yopapatiza kamalola zinthu za antenna zozungulira kuyikidwa pamwamba ndi m'mbali, zomwe zimapangitsa kuti kufalikira kwa array kukhale kwakukulu komanso magwiridwe antchito. Kapangidwe kameneka kamalola array kutulutsa ma beams angapo mwanjira ya stereoscopic, motero kumawonjezera mphamvu zolandirira ndi kutumiza kwa dongosolo la antenna.
Chimodzi mwa zinthu zofunika kwambiri pa kapangidwe ka nsanja yopapatiza ndi mawonekedwe okhazikika a pamwamba pa polygonal, zomwe zimapangitsa kuti zinthu za antenna zigawike mofanana komanso kuti zigwire bwino ntchito yonse ya gulu. Izi zimatsimikizira kuti gululi likhoza kupereka mphamvu yodalirika komanso yokhazikika ya chizindikiro pa ntchito zosiyanasiyana komanso malo osiyanasiyana.
