Kodi antenna ya nyanga ya lenzi ndi chiyani?
Antena ya Horn ya Lensndi kapangidwe kapadera ka antenna komwe kamaphatikiza mawonekedwe a lenzi ndi zinthu za nyanga. Kamagwiritsidwa ntchito kwambiri mu njira zolumikizirana ndi radar mu ma microwave ndi ma millimeter wave band. Ma parameter osiyanasiyana a antenna ya nyanga ya lenzi adzafotokozedwa mwatsatanetsatane pansipa.
Kupeza: Kupeza ndi kuthekera kwa antenna kusintha mphamvu yamagetsi yobwera kukhala mphamvu yowala. Mu ma antenna a lens horn, kupeza nthawi zambiri ndi chiŵerengero cha mphamvu yayikulu yowala yomwe imachokera ku kuwala kwakukulu kwa antenna kupita ku mphamvu yayikulu yowala ya antenna yowunikira (monga antenna yoyenera). Kupeza ndi chizindikiro chofunikira cha magwiridwe antchito a antenna ndipo kumakhudza mwachindunji mtunda wolumikizirana ndi kukhudzidwa kwa antenna.
M'lifupi mwa denga: M'lifupi mwa denga ndi mtunda wa ma radiation a antenna mu mbali yaikulu ya denga. Pa ma antenna a lenzi-nyanga, m'lifupi mwa denga ndi mtunda wa ma radiation zimadalira kapangidwe ka nyanga ndi mawonekedwe a lenzi. M'lifupi mwa denga ndi mtunda wa ma radiation zimasonyeza kuti antenna ili ndi mbali yolunjika komanso yolunjika bwino.
Mlingo wa mbali: Mlingo wa mbali umatanthauza mlingo wa mphamvu ya mphamvu yowala m'njira zina osati njira ya kuwala poyerekeza ndi kuwala kwakukulu. Mlingo wa mbali ukakhala wotsika, mphamvu ya kuwala ya antenna imakhala yolimba kwambiri, yomwe imakhala ndi magwiridwe antchito abwino komanso oletsa kusokoneza.
Chiŵerengero cha mafunde oima: Chiŵerengero cha mafunde oima chimatanthauza kuchuluka kwa kufananiza kwa impedance kumapeto kwa antenna. Mu ma antenna a lens horn, muyeso wa chiŵerengero cha mafunde oima ungagwiritsidwe ntchito kuwunika momwe antenna imagwirizanirana ndi impedance imagwirira ntchito komanso momwe chizindikiro chimagwirizanirana bwino. Chiŵerengero chochepa cha mafunde oima chimasonyeza kufananiza bwino kwa impedance pakati pa antenna ndi mzere wotumizira.
Ma frequency range: Ma frequency range amatanthauza ma frequency range omwe antenna ingagwire ntchito bwino. Ma antenna a lens horn nthawi zambiri amapangidwa kuti azigwiritsidwa ntchito mu frequency band inayake, ndipo ma frequency range awo amadalira mawonekedwe a antenna ndi zipangizo.
Mtunda wogwira ntchito moyenera: Mtunda wogwira ntchito moyenera umatanthauza mtunda wapamwamba kwambiri womwe antenna ingapezere magwiridwe antchito abwino komanso mtundu wabwino wotumizira uthenga mu dongosolo lolumikizirana kapena radar. Gawoli likugwirizana ndi zinthu monga kukwera kwa antenna, kukula kwa beam ndi momwe zinthu zilili.
Miyeso ya Kapangidwe: Miyeso ya kapangidwe imatanthauza kukula ndi mawonekedwe enieni a antenna. Pa ma antenna a nyanga ya lenzi, miyeso ya kapangidwe imakhudza momwe antenna imayankhira pafupipafupi, m'lifupi mwake, komanso mawonekedwe a kuwala.
Ma parameter a antenna ya nyanga ya lenzi ndi monga gain, beam width, side lobe level, standing wave ratio, frequency range, efficient working distance ndi kukula kwa kapangidwe kake. Ma parameter awa amaganizira zinthu monga antenna performance, directionactivity, impedance matching, frequency adaptability ndi physical size, ndipo ndi ofunikira kwambiri pakupanga, kukonza ndi kugwiritsa ntchito antenna.
