Nyanga antenna ndeimwe yeantenna anoshandiswa zvakanyanya ane chimiro chakareruka, yakafara frequency renji, yakakura simba simba uye yakakwirira kuwana.Nyanga antennasanowanzo shandiswa seantenna yekudyisa mune yakakura-yeredhiyo nyeredzi, setiraiti yekutevera, uye yekutaurirana antenna.Pamusoro pekushanda sechikafu chezviratidziro nemalenzi, chinhu chakajairika muzvikamu zvakarongwa uye chinoshanda seyakajairwa chiyero chekugadzirisa uye kuwana zviyero zvemamwe antenna.
Nyanga antenna inoumbwa nekuvhura zvishoma nezvishoma rectangular waveguide kana denderedzwa waveguide neimwe nzira.Nekuda kwekuwedzera zvishoma nezvishoma kweiyo waveguide muromo wepamusoro, kuenzanirana pakati peiyo waveguide nenzvimbo yemahara inovandudzwa, ichiita iyo yekuratidzira coefficient idiki.Kune iyo yakadyiswa rectangular waveguide, imwe-modhi yekufambisa inofanirwa kuwanikwa zvakanyanya sezvinobvira, ndiko kuti, mafungu eTE10 chete anofambiswa.Izvi hazvisi kungoisa simba rechiratidzo uye kuderedza kurasikirwa, asiwo kunodzivirira kukanganisa kwekupindira kwe-inter-mode uye kuwedzera kupararira kunokonzerwa nemaitiro akawanda..
Zvinoenderana neakasiyana nzira dzekutumira dzenyanga antennas, dzinogona kukamurwa kuitasector antennas, piramidhi horn antennas,conical nyanga antennas, makora enyanga antennas, ridged nyanga antennas, multi-mode horn antennas, etc. Aya anowanzo nyanga antenna anotsanangurwa pasi apa.Nhanganyaya mumwe nemumwe
Sector nyanga antenna
E-ndege sector horn antenna
Iyo E-ndege chikamu chenyanga antenna yakagadzirwa nerectangular waveguide yakavhurwa pane imwe kona munzira yemunda wemagetsi.
Nhamba iri pazasi inoratidza mhedzisiro yeE-ndege chikamu chenyanga antenna.Zvinogona kuonekwa kuti hupamhi hwedanda remuenzaniso uyu muE-ndege nzira yakamanikana kupfuura muH-ndege nzira, iyo inokonzerwa neaperture yakakura yeE-ndege.
H-ndege sector nyanga antenna
Iyo H-ndege chikamu chenyanga antenna yakagadzirwa nerectangular waveguide yakavhurwa pane imwe kona munzira yegineti.
Mufananidzo uri pazasi unoratidza mhedzisiro yeH-ndege chikamu chenyanga antenna.Zvinogona kuonekwa kuti hupamhi hwedanda remuenzaniso uyu muH-ndege nzira iduku kudarika muE-ndege nzira, iyo inokonzerwa nehombe huru yeH-ndege.
RFMISO chikamu chenyanga antenna zvigadzirwa:
RM-SWA187-10
RM-SWA28-10
Piramidhi Nyanga Antenna
Iyo piramidhi nyanga antenna yakagadzirwa nerectangular waveguide inovhurwa pane imwe kona munzira mbiri panguva imwe chete.
Mufananidzo uri pazasi unoratidza mhedzisiro yepiramidal horn antenna.Hunhu hwayo hwemwaranzi ndeye musanganiswa weE-ndege uye H-ndege chikamu nyanga.
Conical nyanga antenna
Kana iyo yakavhurika magumo edenderedzwa waveguide yakaita senyanga, inodaidzwa kuti conical nyanga antenna.Koni yenyanga antenna ine denderedzwa kana elliptical aperture pamusoro payo.
Mufananidzo uri pazasi unoratidza mhedzisiro yeiyo conical horn antenna.
RFMISO conical nyanga antenna zvigadzirwa:
RM-CDPHA218-15
RM-CDPHA618-17
Corrugated nyanga antenna
Runyanga runyanga runyanga runyanga runyanga rune mukati rwakaita makora.Iyo ine mabhenefiti ehupamhi frequency bhendi, yakaderera muchinjiko-polarization, uye yakanaka danda symmetry kuita, asi chimiro chayo chakaoma, uye kuoma kwekugadzirisa uye mutengo wakakwira.
Corrugated nyanga antennas inogona kukamurwa kuita marudzi maviri: pyramidal corrugated nyanga antennas uye conical corrugated nyanga antennas.
RFMISO corrugated nyanga antenna zvigadzirwa:
RM-CHA140220-22
Pyramidal corrugated nyanga antenna
Conical corrugated nyanga antenna
Mufananidzo uri pazasi unoratidza mhedzisiro yeiyo conical corrugated nyanga antenna.
Ridged nyanga antenna
Kana iyo frequency yekushanda yeyakajairika nyanga antenna yakakura kupfuura 15 GHz, iyo yekumashure lobe inotanga kupatsanurwa uye rutivi rwobe level inowedzera.Kuwedzera ridge chimiro kune mutauri cavity kunogona kuwedzera bandwidth, kuderedza impedance, kuwedzera kuwana, uye kuwedzera kutungamira kwemwaranzi.
Ridged nyanga antennas anonyanya kukamurwa kuita kaviri-ridged nyanga antennas uye ina-ine ridged nyanga antennas.Inotevera inoshandisa yakajairika piramidhi yakapetwa kaviri nyanga antenna semuenzaniso wekutevedzera.
Pyramid Double Ridge Horn Antenna
Kuwedzera maviri ridge zvimiro pakati pechikamu chewaveguide uye nyanga yekuvhura chikamu ndeye mbiri-ridge nyanga antenna.Chikamu chewaveguide chakakamurwa kuita mhango yekumashure uye ridge waveguide.Iyo yekumashure mhango inogona kusefa iyo yepamusoro-yerodhi modes inofara mune waveguide.Iyo ridge waveguide inoderedza cutoff frequency yeiyo main mode kutapurirana, nekudaro ichizadzisa chinangwa chekuwedzera frequency bhendi.
Iyo ridged nyanga antenna idiki pane yakajairika nyanga antenna mune imwechete frequency bhendi uye ine yakakwira bhendi kupfuura general nyanga antenna mune imwechete frequency bhendi.
Mufananidzo uri pazasi unoratidza mhedzisiro yepiramidal-yakapetwa kaviri nyanga antenna.
Multimode nyanga antenna
Muzvishandiso zvakawanda, manyanga antenna anodiwa kuti ape symmetrical mapatani mundege dzese, chikamu chepakati masangana mundege dze$E $ ne$H $, uye kudzvinyirirwa kwepadivi.
Iyo yakawanda-modhi yekukurudzira nyanga chimiro inogona kuvandudza danda rekuenzana mhedzisiro yendege yega yega uye kuderedza danho reparutivi.Imwe yeanonyanya kufarirwa multimode nyanga antenna ndeye mbiri-modhi conical nyanga antenna.
Dual Mode Conical Horn Antenna
Iyo mbiri-modhi yekoni nyanga inonatsiridza iyo $E $ plane pattern nekuunza yepamusoro-order mode TM11 mode, kuitira kuti pateni yayo ine axially symmetrical yakaenzana danda maitiro.Mufananidzo uri pazasi idhizaini yedhizaini yeaperture electric field distribution of the main mode TE11 mode uye yepamusoro-order mode TM11 in a circular waveguide and its synthesized aperture field distribution.
Iyo yekumisikidza fomu yehuviri-modhi conical horn haisi yega.Nzira dzakajairika dzekushandisa dzinosanganisira Potter horn uye Pickett-Potter nyanga.
Mufananidzo uri pazasi unoratidza mhedzisiro yePotter dual-mode conical horn antenna.
