Zomwe ndi mbale za satellite komanso zolunjika

Ma Antennas okhala ndi gawo lagalasi amagawidwa kukhala offset ndi Direct focus. Zonsezi ndi mbale zowoneka bwino, koma zimakhala ndi kusiyana kwakukulu. Mlongoti wa offset sagwiritsidwa ntchito mochuluka ngati wachiwiri. Palinso dzina lina la antennas olunjika – axisymmetric, popeza symmetry yawo imamangidwa mozungulira mbali imodzi. Galasi lawo ndi paraboloid ya revolution, mawonekedwe ake ndi ozungulira, kapangidwe kake kamathandizira kuti pakhale mgwirizano wa geometric axis ndi magetsi. Pamtunda womwewo pali chosinthira chomwe chimamangiriridwa m’mphepete mwa chowonetsera ndi zomangamanga zapadera. [id id mawu = “attach_3559” align = “aligncenter” wide = “400”]
Mbale yoyang’ana mwachindunji [/ mawu] Mlongoti wothandizira akuwoneka kuti wadulidwa ndi parabola. Paraboloid nthawi zambiri imadutsana ndi silinda. Nkhwangwa zawo nthawi zonse zimayendera limodzi. Galasi la mlongoti wotere limakhala ndi mawonekedwe a elliptical, ndipo chingwe chamagetsi chimapatuka ndi ngodya inayake kuchokera ku geometric.

Mlongoti wa Offset [/ mawu] Tinyanga zonse zili ndi zabwino komanso zoyipa. Mlongoti wolunjika mwachindunji umalola kugwiritsa ntchito bwino malo agalasi. The offset antenna ili ndi mawonekedwe osiyana pang’ono. Kuti mupeze malo ogwira mtima, munthu ayenera kuchulukitsa thupi ndi cosine ya ngodya pakati pa nkhwangwa ziwiri: zamagetsi ndi geometric. Koma ndi mlongoti wachindunji wolunjika, gawo lalikulu la pamwamba limabisika ndi chosinthira ndi phiri lomwe likugwirizana nalo, zomwe sizikugwira ntchito ku mitundu ina ya tinyanga. Chifukwa chake, tinyanga tolunjika nthawi zambiri zimakhala zazikulu. Mu mlongoti wa axisymmetric, womwe umakwezedwa kumalo ena abwino, mpweya umachulukana. Tinyanga tating’ono tating’ono tating’ono tating’ono tating’onoting’ono kapena tapendekeka pansi, ndipo sizimadziunjikira mvula mwa iwo okha. Koma, popeza chosinthira chimayang’ana mmwamba, chiyenera kukhala chopanda mpweya, kuti madzi asalowemo. Ubwino wina wa antenna yochotsera ndikuti malo onse a mphamvu yokoka amasunthidwa pansi chifukwa cha bracket ndi converter, zomwe zimawonjezera kulemera pansi. Mlongoti wokhazikika wokhazikika kunyumba:
