Kupfuta kweantenna yenyanga ndiko kuwedzera zvishoma nezvishoma kwenzira yekufambisa mafungu kubva pahuro payo kuenda paburi guru rinopenya.Kuchinja uku kunobvumira munda wemagetsi unotungamirirwa kuti upararire usati wasvika panzvimbo yakasununguka, zvichibatsira antenna kuwana kuenderana kwe impedance, kutungamira uye kudzora danda.
Zvinorevei Kupenya MuAntena Yenyanga?
Ruzivo rwakavhurika rwemafungu runogona kupenya, asi muganhu uripo pakati peruzivo nenzvimbo yakasununguka unokonzera kupenya uye unoderedza mukana wekupenya unoshanda. Honye yakapfurwa inochinja chikamu cheruzivo rwemafungu zvishoma nezvishoma pane kungoerekana yaitika.
Sezvo munda uchifamba nemumupata, unokura uchienda kune rimwe goho guru. Saizi yemupata uye kugoverwa kwechikamu zvinozosarudza hunhu hwakakosha hwakadai sekuwedzera, hupamhi hwemwenje, marobhoti emativi uye kushanda zvakanaka kwemwaranzi. Kupenya kunoderedza kuoma kwekuchinja, asi hakubvisi kuratidzwa kana kuvimbisa kuenderana kwakakwana.
Nei Kupenya kweAntena yeNyanga Kuchikosha
Kufananidza Impedance uye VSWR
Kuchinja zvishoma nezvishoma kunowanzo deredza kusawirirana pakati peguided mode nenzvimbo yakasununguka. Mhedzisiro chaiyo inoenderana neprofile yehorn, kureba, aperture uye saizi yewaveguide, saka VSWR inofanira kusimbiswa kuburikidza nebhendi refrequency rakarongwa.
Kuwana uye Kuvhura Kunobudirira
Kupfuta kunoita kuti pave nemwaranzi yakakura inoshanda. Kana nzvimbo yekupfuta iine amplitude yakakodzera uye phase distribution, simba rakawanda rinoiswa mberi uye kuwedzera kweantenna kunowedzera. Kukwira hakuonekwi ne flare angle chete.
Pattern yeBeamwidth neRadiation
Aperture yakakura yemagetsi inowanzoita kuti pave nedanda guru rakatetepa. Makuriro eE-plane neH-plane flare anogona kusarudzwa ari ega muhwamanda yepiramidhi, zvichibvumira vagadziri kugadzira danda mugwara rega rega guru.
Chikanganiso cheAperture Phase
Munda hausviki panzvimbo yega yega yegomba rine chikamu chimwe chete. Kana nyanga iri pfupi zvakanyanya kupfuura saizi yegomba rayo, kuchinja kwechikamu kunogona kuwedzera, zvichideredza kushanda kwegomba uye zvichikanganisa danda guru nemativi eparutivi.
Mashandiro anoita Flare Angle, Aperture Size uye Hole yeNyanga
Hapana kona yepamusoro-soro yeflare yeantenna yega yega. Maitiro akakodzera ekuita zvinhu anoenderana nehuwandu, waveguide mode, target gain, beamwidth, bandwidth, permission size uye radiation-pattern zvinodiwa.
- Kona yakafara yekupenyainogona kuburitsa goho guru muchimiro chipfupi, asi goho pfupi zvakanyanya rinogona kukonzera kukanganisa kukuru kwechikamu chekuvhura goho.
- Kona diki yekupenyakazhinji inoda nyanga refu yehukuru hwakafanana hwekuvhura, zvichiwedzera kureba kwemuchina uku zvichitsigira kuchinja zvishoma nezvishoma.
- Aperture yakakurainogona kutsigira kutungamira kwepamusoro uye danda rakatetepa, chero bedzi kugoverwa kwechikamu nehukuru zvichiramba zvichidzorwa zvakanaka.
Majometri Enyanga Dzakapararira Akajairika
- Horn yemagetsi yechikamu:yakapfuta zvikuru mundege yemagetsi.
- H-plane sectoral horn: nyanga yemhando yepamusoro:yakapfuta zvikuru mumhepo ine simba remagineti.
- Nyanga yepiramidhi:inopenya muzvikamu zvikuru uye inowanzoshandiswa pakushandisa zvinhu zvakajairwa.
- Nyanga ine denderedzwa remakona:yakagadzirwa kubva padenderedzwa remafungu uye yakatambanudzwa ichienda kune denderedzwa.
Kufungisisa Nezvekugadzira Kunoshanda
Mainjiniya vanoongorora mafambiro emagetsi pamwe chete nemafambiro ekushanda, saizi yewaveguide, gain, 3 dB beamwidth, VSWR, sidelobe level, polarization uye zvirambidzo zvemakanika. Pama frequency e millimeter-wave, kurongeka kwe machining, kunaka kwe surface uye flange alignment zvinova zvakakosha nekuti zvikanganiso zvidiki zvinomiririra chikamu chikuru che wavelength.
Zvikamu zve15–22 GHz zvine hukama neWaveguide
Zvigadzirwa zviri pazasi zvinoratidza zvikamu zvakasiyana-siyana zveRF zviripo muhuwandu hwe15–22 GHz. Kuti uwane nyanga yemagetsi inopenya mubhendi iri, ona RM-SGHA51-25.
Kunoshandiswa MaAntenna Enyanga Dzakapfurwa
- Kuyera maAntena uye masisitimu ekugadzirisa
- Masisitimu ekutumira nekugamuchira maRadar
- Satellite uye reflector-antenna feeds
- Kuongororwa kweEMC uye microwave laboratory
- Zvinongedzo zvekutaurirana zvema microwave ne millimeter-wave
Mibvunzo Inowanzo bvunzwa
Ko kona yakakura yekupenya inowedzera kuwedzera here?
Kwete. Kona yakakura yekupenya inogona kuwedzera saizi yekuvhura kwese kwese kwehonye yakatarwa, asi kukanganisa kwakanyanya kwechikamu kunogona kuderedza kushanda zvakanaka kwevhura. Kukura kunoenderana nejometri yakazara uye kugoverwa kwemunda.
Ndeipi kona yakanakisa ye flare ye antenna ye nyanga?
Hapana chinhu chimwe chete chakanakisa. Vagadziri vanosarudza kona pamwe chete nehukuru hwe aperture uye kureba kwenyanga kuti zvienderane ne frequency, gain, beamwidth, VSWR uye saizi zvinodiwa.
Kupisa kunobvisa kupenya kwechiedza here?
Kwete. Flaring inopa shanduko zvishoma nezvishoma kubva pakutungamira kwemafungu kuenda kunzvimbo yakasununguka uye inogona kuderedza kuratidzwa, asi mutambo wekupedzisira uchiri kuenderana nekugadzirwa kwakazara.
Kusarudza Antena yeNyanga
