Antena yenyanga ndeimwe yeantena dzinoshandiswa zvakanyanya dzine chimiro chiri nyore, frequency yakafara, simba guru uye gain yakakwira.Maenjere enyangaanowanzo shandiswa semaantenna ekudyisa mukuongorora nyeredzi dzeredhiyo, kutevedza satellite, uye maantenna ekutaurirana. Pamusoro pekushanda semaantenna ekuratidza magirazi nemalenzi, chinhu chakajairika muzvikamu zvakarongwa uye chinoshanda sechiyero chakajairika chekuyera nekuyera kwemamwe maantenna.
Antena yenyanga inoumbwa nekuvhura zvishoma nezvishoma rectangular waveguide kana denderedzwa waveguide nenzira chaiyo. Nekuda kwekuwedzera zvishoma nezvishoma kwemuromo we waveguide, kuenderana pakati pe waveguide nenzvimbo yakasununguka kunovandudzwa, zvichiita kuti reflection coefficient ive diki. Kune fed rectangular waveguide, single-mode transmission inofanira kuwanikwa zvakanyanya sezvinobvira, kureva kuti, mafungu eTE10 chete ndiwo anotumirwa. Izvi hazvingosanganisi simba rechiratidzo chete uye zvinoderedza kurasikirwa, asiwo zvinodzivirira kukanganiswa kwe inter-mode interference uye kuwedzera kupararira kunokonzerwa ne multiple modes. .
Zvichienderana nenzira dzakasiyana dzekushandisa antenna dzenyanga, dzinogona kukamurwa kuitaantenna dzehorn dzechikamu, antenna dzenyanga dzepiramidhi,antenna dzenyanga dzakaita sekona, antenna dzenyanga dzakakombama, maantenna ane nyanga dzakapinza, maantenna ane nyanga dzakawanda, nezvimwewo. Aya maantenna ane nyanga dzakajairika anotsanangurwa pazasi. Nhanganyaya imwe neimwe
Antena yenyanga yechikamu
E-ndege chikamu nyanga antenna
Antena yeE-plane sector horn yakagadzirwa nerectangular waveguide yakavhurwa nekona yakati rebei munzira yemagetsi.
Mufananidzo uri pazasi unoratidza mhedzisiro yekutevedzera kweantenna yeE-plane sector horn. Zvinogona kuonekwa kuti upamhi hwemuti uyu munzira yeE-plane hwakatetepa pane munzira yeH-plane, izvo zvinokonzerwa nekuvhurika kukuru kweE-plane.
Antena yeH-plane sector horn
Antena yeH-plane sector horn yakagadzirwa nerectangular waveguide yakavhurwa nekona yakati rebei munzira yemagnetic field.
Mufananidzo uri pazasi unoratidza mhedzisiro yekutevedzera kweantenna yeH-plane sector horn. Zvinogona kuonekwa kuti upamhi hwemuti wepatani iyi munzira yeH-plane hwakatetepa pane munzira yeE-plane, izvo zvinokonzerwa nekuvhurika kukuru kweH-plane.
Zvigadzirwa zveRFMISO sector horn antenna:
RM-SWHA187-10
RM-SWHA28-10
Antena yePiramidhi yeNyanga
Antena yenyanga yepiramidhi yakagadzirwa negwara remafungu re rectangular rinovhurwa nekona yakati munzira mbiri panguva imwe chete.
Mufananidzo uri pazasi unoratidza mhedzisiro yekutevedzera kweantenna yenyanga yepiramidhi. Hunhu hwayo hwemwaranzi hunowanzova musanganiswa wenyanga dzeE-plane nedzeH-plane.
Kanyanga yekona ine denderedzwa
Kana mugumo wakavhurika wegwara remafungu rakatenderera wakaita senyanga, unonzi antenna yehorn ine denderedzwa. Antena yehorn ine denderedzwa kana kuti denderedzwa pamusoro payo.
Mufananidzo uri pazasi unoratidza mhedzisiro yekutevedzera kweantenna yehorn ine denderedzwa.
Zvigadzirwa zveRFMISO nyanga ine denderedzwa remakona:
RM-CDPHA218-15
RM-CDPHA618-17
Kanyanga yeCorrugated
Antena ine nyanga yakakombama iantena ine nyanga ine pamusoro pemukati wakakombama. Ine zvakanakira zveband yakafara, polarization yakaderera, uye kushanda zvakanaka kwebeam symmetry, asi chimiro chayo chakaoma, uye kuoma kwekugadzirisa nemutengo wakakwira.
Maantenna enyanga ane corrugated anogona kukamurwa kuita mhando mbiri: maantenna enyanga ane corrugated pyramidal uye maantenna enyanga ane corrugated conical.
Zvigadzirwa zveRFMISO nyanga ye antenna yakagadzirwa ne corrugated:
RM-CHA140220-22
Kanyanga yePyramidal yakakombama
Kanyanga yekona ine denderedzwa ine makona
Mufananidzo uri pazasi unoratidza mhedzisiro yekutevedzera kweantenna yekona ine corrugated horn.
Antena ine nyanga ine miganhu
Kana frequency yekushanda kweantenna yehorn yemazuva ano ichipfuura 15 GHz, lobe yekumashure inotanga kupatsanuka uye huwandu hwelobe yekumativi hunowedzera. Kuwedzera chimiro chemupendero kune speaker cavity kunogona kuwedzera bandwidth, kuderedza impedance, kuwedzera gain, uye kuwedzera divi remwaranzi.
Maantenna ehorn ine ridge akakamurwa kuita maantenna ehorn ine ridge mbiri uye maantenna ehorn ine ridge ina. Inotevera inoshandisa antenna yehorn ine ridge mbiri inowanzo shandiswa semuenzaniso wekuenzanisa.
Antena yePiramidhi Double Ridge Horn
Kuwedzera zvivakwa zviviri zve ridge pakati pechikamu che waveguide nechikamu chekuvhura horn kune antenna ine double-ridge horn. Chikamu che waveguide chakakamurwa kuita back cavity ne ridge waveguide. Back cavity inogona kusefa higher-order modes excited mu waveguide. Ridge waveguide inoderedza cutoff frequency ye main mode transmission, nokudaro ichizadzisa chinangwa chekuwedzera frequency band.
Antena yehorn ine ridged idiki pane antenna yehorn inowanikwa mubhendi rimwe chete refrequency uye ine gain yakakwira kupfuura antenna yehorn inowanikwa mubhendi rimwe chete refrequency.
Mufananidzo uri pazasi unoratidza mhedzisiro yekutevedzera kweantenna yenyanga ine mativi maviri yepiramidhi.
Kanere yenyanga yeMultimode
Muzvizhinji zvezvishandiso, maantenna enyanga anodiwa kuti ape mapatani akafanana muzvikamu zvese, kusangana kwepakati pechikamu muzvikamu zve $E$ ne $H$, uye kudzvinyirirwa kwerutivi rwekumashure.
Chimiro chehorn yekumutsa ine maitiro akawanda chinogona kuvandudza mhedzisiro yekuenzanisa kwebeam yendege yega yega uye kuderedza level yelobe yedivi. Imwe yeantennas dzehorn dzemhando dzakawanda dzinozivikanwa ihorn ine maitiro maviri ine conical.
Dual Mode Conical Horn Antenna
Nyanga yekoni ine maitiro maviri inovandudza patani ye $E$ plane nekuunza modhi yemhando yepamusoro yeTM11, kuitira kuti patani yayo ive nehunhu hwe equalized beam hunoenderana ne axially. Mufananidzo uri pazasi idhayagiramu ye aperture electric field distribution ye main mode TE11 mode uye higher-order mode TM11 mu circular waveguide uye synthesized aperture field distribution yayo.
Maitiro ekugadzira nyanga ine hunyanza huviri haana kusiyana. Nzira dzinoshandiswa dzinosanganisira nyanga yePotter nenyanga yePickett-Potter.
Mufananidzo uri pazasi unoratidza mhedzisiro yekutevedzera kweantenna yePotter ine nyanga ine makona maviri.
