Kuphulika kwa antenna ya nyanga ndi kukula pang'onopang'ono kwa wotsogolera mafunde kuchokera pakhosi pake kupita ku malo otseguka kwambiri.Kusinthaku kumalola kuti gawo lamagetsi lotsogozedwa lifalikire lisanafike pamalo omasuka, zomwe zimathandiza kuti antenna ikwaniritse kufananiza kwa impedance, kuwongolera, ndi kuwongolera kuwala.
Kodi Kuwotcha Kumatanthauza Chiyani mu Antena ya Horn?
Chitsogozo chosavuta chotseguka chimatha kung'anima, koma malire adzidzidzi pakati pa chitsogozo cha mafunde ndi malo omasuka amachititsa kuwunikira ndikuchepetsa kutsegula bwino kwa kuwala. Honi yoyaka imasintha gawo la chitsogozo cha mafunde pang'onopang'ono m'malo mwa mwadzidzidzi.
Pamene munda ukuyenda kudzera mu flare, umakula kudutsa mu flare yayikulu. Kukula kwa flare ndi kugawa kwa gawo kumatsimikizira makhalidwe ofunikira monga gain, beamwidth, sidelobes ndi mphamvu ya radiation. Flaring imachepetsa kuopsa kwa kusintha, koma sikuchotsa kuwunikira kapena kutsimikizira kufanana kwabwino.
Chifukwa Chake Kuphulika kwa Antena ya Horn N'kofunika
Kufananiza kwa Impedance ndi VSWR
Kusintha pang'onopang'ono nthawi zambiri kumachepetsa kusalingana pakati pa njira yotsogozedwa ndi malo omasuka. Zotsatira zenizeni zimadalira mbiri ya horn, kutalika, kutsegula ndi kukula kwa waveguide, kotero VSWR iyenera kutsimikiziridwa kudutsa gulu la ma frequency lomwe mukufuna.
Kupeza Mpata Wogwira Ntchito
Kuwotcha kumapanga malo otseguka bwino kwambiri. Pamene malo otseguka ali ndi ma amplitude ndi kugawa koyenera kwa gawo, mphamvu zambiri zimayikidwa kutsogolo ndipo kuwonjezeka kwa antenna kumawonjezeka. Kuwonjezeka sikumatsimikiziridwa ndi ngodya ya flare yokha.
Chitsanzo cha Beamwidth ndi Radiation
Chitseko chachikulu chamagetsi nthawi zambiri chimapanga mtanda waukulu wopapatiza. Miyeso ya E-plane ndi H-plane flare imatha kusankhidwa payokha mu nyanga ya piramidi, zomwe zimathandiza opanga kupanga mtandawo mu mzere uliwonse waukulu.
Cholakwika cha Gawo Lotseguka
Mundawu sufika pamalo onse a dzenje ndi gawo lomwelo. Ngati nyanga ndi yayifupi kwambiri poyerekeza ndi kukula kwa dzenje lake, kusintha kwa gawo kumatha kuwonjezeka, zomwe zimachepetsa mphamvu ya dzenje ndikukhudza chitsulo chachikulu ndi ma sidelobes.
Momwe Mng'alu Woyaka, Kukula kwa Mpata ndi Utali wa Nyanga Zimagwirira Ntchito Pamodzi
Palibe ngodya yabwino kwambiri yowunikira ma antenna onse a horn. Kuchuluka kwa ma antenna kumadalira ma frequency, waveguide mode, target gain, beamwidth, bandwidth, kukula kovomerezeka ndi zofunikira pa radiation-pattern.
- Ngodya yokulirapoikhoza kupanga dzenje lalikulu m'kapangidwe kakafupi, koma nyanga yayifupi kwambiri ingayambitse vuto lalikulu la dzenje.
- Ngodya yaying'ono yowalaKawirikawiri imafuna nyanga yayitali yokhala ndi kukula kofanana kwa malo otseguka, kuwonjezera kutalika kwa makina pamene ikuthandiza kusintha pang'onopang'ono.
- Chitseko chachikuluimatha kuthandizira kuwongolera kwapamwamba komanso kuwala kopapatiza, bola ngati gawo ndi kugawa kwa amplitude zikupitilira kulamulidwa bwino.
Ma Geometries Odziwika a Nyanga Yowala
- Honi yamagetsi yamagetsi:inayaka makamaka mu ndege yamagetsi.
- Horn ya H-plane sectoral:imayaka makamaka mu ndege ya magnetic-field.
- Nyanga ya piramidi:imayaka m'magulu onse awiri akuluakulu ndipo imagwiritsidwa ntchito kwambiri pa ntchito zodziwika bwino.
- Nyanga yozungulira:yopangidwa kuchokera ku chitsogozo cha mafunde ozungulira ndipo inakula kupita ku malo ozungulira.
Zoganizira Zothandiza Pakupanga
Mainjiniya amayesa mawonekedwe a flare pamodzi ndi ma frequency operating, ma waveguide dimensions, gain, 3 dB beamwidth, VSWR, sidelobe level, polarization ndi mechanical comprominations. Pa ma millimeter-wave frequency, machining accuracy, surface quality, ndi flange alignment zimakhala zofunika kwambiri chifukwa zolakwika zazing'ono zimayimira gawo lalikulu la wavelength.
Ma Antena Ogwirizana a 15–22 GHz ndi Zigawo za Waveguide
Zogulitsa zomwe zili pansipa zikuwonetsa zigawo zingapo za RF zomwe zikupezeka mu 15–22 GHz. Kuti mupeze nyanga yodziwika bwino ya gain horn mu gulu ili, onani RM-SGHA51-25.
Kumene Ma Antenna a Nyanga Yoyaka Amagwiritsidwa Ntchito
- Kuyeza ndi kuwerengera ma antenna
- Makina otumizira ndi kulandira ma radar
- Ma feed a satellite ndi reflector-antenna
- Kuyesa kwa EMC ndi ma microwave mu labotale
- Maulalo olumikizirana a maikulowevu ndi ma millimeter-wave
Mafunso Ofunsidwa Kawirikawiri
Kodi ngodya yokulirapo nthawi zonse imawonjezera phindu?
Ayi. Ngodya yokulirapo ya flare ingawonjezere kukula kwa thumba kuti nyanga ikhale yokhazikika, koma cholakwika chachikulu cha gawo chingachepetse kugwira ntchito bwino kwa thumba. Kuchuluka kwa thumba kumadalira mawonekedwe onse ndi kufalikira kwa thumba.
Kodi ngodya yabwino kwambiri ya antenna ya horn ndi iti?
Palibe mtengo umodzi wabwino kwambiri. Opanga mapulani amasankha ngodya pamodzi ndi kukula kwa malo otseguka ndi kutalika kwa nyanga kuti akwaniritse zofunikira pa mafupipafupi, kukula, m'lifupi, VSWR ndi kukula.
Kodi kuphulika kwa moto kumachotsa kuwunikira?
Ayi. Kuwotcha kumapereka kusintha pang'onopang'ono kuchokera ku waveguide kupita ku malo omasuka ndipo kungachepetse kuwunikira, koma machesi omaliza amadalirabe kapangidwe kake konse.
Kusankha Antena ya Horn
