Nhoroondo yenyanga antennas yakatanga muna 1897, apo muongorori weredhiyo Jagadish Chandra Bose akaita mapiyona ekuedza madhizaini achishandisa mamicrowave. Gare gare, GC Southworth naWilmer Barrow vakagadzira chimiro chemazuva ano nyanga antenna muna 1938 zvakateerana. Kubva ipapo, magadzirirwo enyanga antenna akaenderera mberi achidzidzwa kutsanangura maitiro avo emwaranzi uye mashandisiro munzvimbo dzakasiyana siyana. Aya antenna ane mukurumbira mundima yewaveguide transmission uye microwaves, saka anowanzo kunzi.microwave antenna. Naizvozvo, chinyorwa ichi chinoongorora mashandiro anoita nyanga antenna uye mashandisiro adzo munzvimbo dzakasiyana siyana.
Chii chinonzi antenna yenyanga?
A nyanga antennaantenna aperture yakagadzirirwa zvakananga microwave frequencies ine yakafara kana nyanga-yakaita magumo. Ichi chimiro chinopa antenna kutungamira kukuru, ichibvumira chiratidzo chakaburitswa kuti chifambiswe zviri nyore pamadaro marefu. Nyanga antennas anonyanya kushanda pa microwave frequencies, saka frequency yavo renji inowanzova UHF kana EHF.
RFMISO nyanga antenna RM-CDPHA618-20 (6-18GHz)
Aya antenna anoshandiswa senyanga dzekudya kune maantenna makuru akadai separabolic uye anotungamira antennas. Zvakanakira zvavo zvinosanganisira kureruka kwekugadzira uye kugadzirisa, yakaderera yakamira wave ratio, ine mwero inotungamira, uye yakakura bandwidth.
Nyanga antenna dhizaini uye kushanda
Nyanga antenna dhizaini inogona kuitwa uchishandisa nyanga-yakaita waveguides yekufambisa uye kugamuchira redhiyo frequency microwave masaini. Kazhinji, iwo anoshandiswa pamwe chete newaveguide feeds uye yakananga masaisai eredhiyo kugadzira matanda matete. Chikamu chinoputika chinogona kuuya mumhando dzakasiyana-siyana, senge square, conical, kana rectangular. Kuti uve nechokwadi chekushanda kwakakodzera, saizi yeantenna inofanira kunge idiki sezvinobvira. Kana iyo wavelength yakakura kwazvo kana saizi yenyanga idiki, antenna haishande nemazvo.
Nyanga antenna dhizaini yekudhirowa
Mune antenna yenyanga, chikamu chesimba rechiitiko chinovhenekerwa kunze kwemusuwo wewaveguide, nepo rimwe simba rose richiratidzwa kumashure kubva pamusuwo mumwe chete nekuti musuwo wakavhurika, zvichikonzera kusabatana kwakashata pakati penzvimbo nenzvimbo. waveguide. Pamusoro pezvo, kumicheto yewaveguide, diffraction inokanganisa kugona kweradiation yewaveguide.
Kuti ukunde kusakwana kweiyo waveguide, iyo yekupedzisira kuvhura inogadzirwa nenzira ye electromagnetic nyanga. Izvi zvinobvumira shanduko yakatsetseka pakati penzvimbo uye waveguide, ichipa zvirinani kunanga kune masaisai eredhiyo.
Nekushandura waveguide senge nyanga chimiro, iyo discontinuity uye 377 ohm impedance pakati penzvimbo uye waveguide inobviswa. Izvi zvinowedzera kutungamira uye kuwana kweiyo antenna yekufambisa nekudzikisa diffraction kumapendero kuti ipe chiitiko simba rinoburitswa munzira yekumberi.
Heano mashandiro anoita antenna yenyanga: Kana imwe mugumo wewaveguide yanakidzwa, magineti inogadzirwa. Panyaya yekupararira kwewaveguide, munda unopararira unogona kudzorwa kuburikidza nemadziro ewaveguide kuitira kuti munda usaparadzire nenzira yakatenderera asi nenzira yakafanana neyemahara nzvimbo yekuparadzira. Kana munda unopfuura wasvika kumagumo ewaveguide, unopararira nenzira imwechete seyemunzvimbo yakasununguka, saka denderedzwa remasaisai rinowanikwa kumagumo ewaveguide.
