Nhoroondo yemaantenna enyanga inotangira mugore ra1897, apo muongorori weredhiyo Jagadish Chandra Bose akaita magadzirirwo ekutanga ekuyedza achishandisa ma microwave. Gare gare, GC Southworth naWilmer Barrow vakagadzira chimiro che antenna yenyanga yemazuva ano muna 1938 zvichiteerana. Kubva ipapo, magadzirirwo ema antenna enyanga ave achidzidzwa nguva dzose kuti atsanangure maitiro avo emwaranzi uye mashandisirwo ayo muminda yakasiyana-siyana. Ma antenna aya anozivikanwa zvikuru mumunda wekutumira ma waveguide uye ma microwave, saka anowanzo nziantenna dze microwaveSaka, chinyorwa chino chichaongorora mashandiro anoita antenna dzehorn uye mashandisirwo adzo muminda yakasiyana-siyana.
Chii chinonzi nyanga yeantena?
A kanyanga yenyangaiantenna yekuvhura yakagadzirwa zvakanangana nema microwave frequency ane mugumo wakakura kana wakaita senyanga. Chimiro ichi chinopa antenna kutungamira kukuru, zvichiita kuti chiratidzo chinoburitswa chifambiswe zviri nyore nedaro refu. Ma antenna enyanga anonyanya kushanda pama microwave frequency, saka huwandu hwawo hwema frequency hunowanzova UHF kana EHF.
Kaneti yenyanga yeRFMISO RM-CDPHA618-20 (6-18GHz)
Maantenna aya anoshandiswa senyanga dzekudyisa maantenna makuru akadai semaantenna eparabolic neakananga. Zvakanakira zvawo zvinosanganisira kurongeka uye kugadziriswa kuri nyore, chiyero chemafungu akamira pasi, gwara riri pakati nepakati, uye bandwidth yakafara.
Dhizaini uye mashandiro eantenna yenyanga
Magadzirirwo eantenna yenyanga anogona kuitwa uchishandisa mawaveguides akaita senyanga ekutumira nekugamuchira masaini e microwave eredhiyo. Kazhinji, anoshandiswa pamwe chete nema waveguides uye mawave eredhiyo anotungamira kugadzira matanda matete. Chikamu chakapfurwa chinogona kuuya mumhando dzakasiyana-siyana, dzakadai sesquare, conical, kana rectangular. Kuti ive nechokwadi chekushanda zvakanaka, saizi yeantenna inofanira kunge iri diki sezvinobvira. Kana wavelength yakakura kwazvo kana saizi yenyanga iri diki, antenna haizoshande nemazvo.
Dhirowa yemufananidzo we antenna yenyanga
Mu antenna ine nyanga, chikamu chesimba rechiitiko chinobuda pasuo re waveguide, nepo simba rasara richiratidzwa kubva pasuo rimwe chete nekuti suo rakavhurika, zvichikonzera kusawirirana kwakanaka pakati penzvimbo ne waveguide. Pamusoro pezvo, pamucheto we waveguide, diffraction inokanganisa kugona kwe radiative kwe waveguide.
Kuti tikwanise kukunda zvikanganiso zvewaveguide, muromo wekupedzisira wakagadzirwa muchimiro chenyanga yemagetsi. Izvi zvinoita kuti pave nekuchinja kwakanaka pakati penzvimbo newaveguide, zvichipa nhungamiro iri nani yemafungu eredhiyo.
Nekuchinja waveguide sechimiro chehorn, discontinuity uye 377 ohm impedance pakati penzvimbo newaveguide zvinobviswa. Izvi zvinowedzera kutungamira uye kuwana kwetransmit antenna nekuderedza diffraction kumucheto kuti ipe simba rezviitiko rinoburitswa munzira yekumberi.
Heino mashandiro anoita antenna yenyanga: Kana mugumo mumwe wewaveguide wafashukira, simba remagineti rinogadzirwa. Panyaya yekupararira kwewaveguide, munda unopararira unogona kudzorwa kuburikidza nemadziro ewaveguide kuitira kuti munda usapararire nenzira yakatenderera asi nenzira yakafanana nekupararira kwenzvimbo yakasununguka. Kana munda unopfuura wasvika kumagumo ewaveguide, unopararira nenzira imwecheteyo semunzvimbo yakasununguka, saka wavefront yakatenderera inowanikwa kumagumo ewaveguide.

Kushandiswa kwe antenna yenyanga
Maantenna aya anonyanya kushandiswa pakutsvaga zvinhu zvemuchadenga uye mashandisirwo anoitwa nema microwave. Anogona kushandiswa sezvinhu zvekudyisa pakuyera ma antenna parameter akasiyana murabhoritari. Pama microwave frequency, ma antenna aya anogona kushandiswa chero bedzi aine gain iri pakati nepakati. Kuti uwane operation ye medium gain, saizi ye antenna ye horn inofanira kunge yakakura. Mhando idzi dze antenna dzakakodzera makamera ekumhanya kudzivirira kukanganiswa ne reflection response inodiwa.
