Maantenna eAperture iboka rakakosha remaantenna anoshandiswa zvakanyanya muma microwave, millimeter-wave, radar, kutaurirana, uye antenna measurement systems. Kusiyana nema antenna ewaya, ayo anonyanya kupenya kuburikidza nemagetsi anoyerera pamwe chete nezvinhu zvinofambisa mhepo, ma antenna eAperture anoburitsa simba remagetsi kuburikidza nepaburi kana aperture.
Muenzaniso unowanzoonekwa igwara remafungu rakavhurika. Kana mafungu emagetsi achifamba nemugwara remafungu osvika kumagumo akavhurika, chikamu chesimba rinotungamirwa chinopfuudzwa munzvimbo yakasununguka. Nekudzora geometry yeaperture, kugoverwa kwemunda, uye chimiro chakakomberedza, mainjiniya anogona kuwedzera kuvandudza hunhu hwe impedance matching, directionivity, gain, uye radiation.
Ma antenna anowanzo shandiswa anosanganisiraantenna dzinotungamirira mafungu dzakavhurika,antenna dzenyanga, uye ma antenna e slotNyaya yekutanga yekutarisa inoisawo zvivako zvitatu izvi pasi pemaantena ekuvhara.
1. Chii chinonzi Antena yeAperture?
Muinjiniya yeantenna, aperture inogona kunzi gomba iro ma electromagnetic fields anobatana kubva pachivako chinotungamirirwa kuenda munzvimbo yakasununguka.
Nzira yekufambisa mafungu yakagadzirirwa kudzikamisa uye kutungamirira simba remagetsi. Kana nzira yekufambisa mafungu ikagumiswa nemadziro anofambisa mafungu, simba racho rinoramba rakavharika kana kuti rinoonekwa zvichienderana nemamiriro ekugumira. Zvisinei, kana nzira yekufambisa mafungu ikavhurwa, nzvimbo yemagetsi iri paburiro inogona kupenya munzvimbo yakasununguka.
Saka, aperture inoshanda senzvimbo yekuchinja pakati peguided electromagnetic mode ne radiated electromagnetic wave.
Hunhu hwemwaranzi chaiyo hunoenderana nezvinhu zvakawanda, zvinosanganisira:
- Zviyero zveAperture uye chimiro
- Kureba kwehurefu hwekushanda
- Maitiro ekutungamira mafungu
- Kugoverwa kwemagetsi nemagnetic field
- Flange kana chimiro chakakomberedza chekufambisa
- Kufananidza kweImpedance paburiro
Tsvagiridzo pamusoro pemafungu erectangular anovhurika inoratidza kuti minda yekuvhura uye diffraction kubva kumicheto yeflange yakapoteredza zvinogona kubatsira kumunda une radiation unobuda.
Mufananidzo 1. Muenzaniso wechimiro cherectangular waveguide chinoshandiswa kuratidza mwaranzi ye aperture.
2. Guide yeMafungu Akazaruka Inoita Sei Kuti Ipenye?
Kana nzira yekufambisa mafungu ichisvika paburi rakavhurika, mamiriro emuganhu wemagetsi anochinja kamwe kamwe. Minda yacho haisisina kuvharirwa zvachose nemadziro ekufambisa, zvichiita kuti chikamu chesimba remagetsi chibudire munzvimbo yakasununguka.
Panguva imwe chete, kuchinja kubva paguide yewave kuenda kunzvimbo yakasununguka kazhinji hakuenderani zvakakwana. Saka rimwe simba rinogona kudzoserwa kumashure muguide yewave.
Hukama uhwu pakatimwaranzi uye kufungisisachikamu chakakosha chekugadzira aperture antenna.
Nzira iri nyore yekufambisa mafungu inogona kushanda seantenna, asi kushanda kwayo zvakanaka kwemwaranzi, kuenderana kweimpedance, gain, uye hunhu hwemwaranzi zvinogona kunge zvisina kunaka kune yega yega application. Mainjiniya anogona kugadzirisa geometry ye aperture kuti awane mashandiro ari nani. Imwe yemienzaniso inozivikanwa zvikuru ndeiyikanyanga yenyanga, umo mafungu anotambanuka zvishoma nezvishoma achienda kuburiro.
3. Kushanda Kwakawanda kweAperture Antennas
Hapana huwandu humwechete hwemafrequency ekushanda anowanikwa kune ese ma aperture antenna.
Mafambiro anoshandiswa eantenna ye aperture yakavakirwa pa waveguide anonyanya kutsanangurwa nesaizi yewaveguide, rudzi rwewaveguide, nzira dzekuparadzira dzinotsigirwa, uye ma cutoff frequency.
Saka saizi dzakasiyana dzema waveguide dzinoshandiswa pamabhandi akasiyana e microwave ne millimeter-wave frequency.
Izvi zvakakosha zvikuru mumasisitimu eRF ane mafrequency akakwira. Sezvo mafrequency achiwedzera uye wavelength ichiva pfupi, miganhu yema waveguide uye aperture inovawo diki, zvichiita kuti ma aperture antenna ashandiswe zvinobudirira muma microwave, millimeter-wave, uye kunyange sub-THz systems.
4. Mutoo wemwaranzi weAntena yeAperture
Maitiro emwaranzi eantenna yekuvhura anotarisa zvakanyanya pahukuru hweaperture, kugoverwa kwemunda, maitiro ekushanda, urefu hwewavelength, uye chimiro chakakomberedza.
Nzira yekufambisa mafungu inovhurika inowanzo gadzira danda rakafara, asi haifanirwe kutsanangurwa otomatiki seantenna inotenderera kwese kwese. Hunhu hwayo hwemwaranzi yeE-plane neH-plane hunoenderana nekupararira kwesimba remagetsi pamusoro peaperture.
Flange yakakomberedza inogonawo kukanganisa patani yemwaranzi inobuda nekuti minda yakaparadzaniswa kubva kumicheto yayo inobatsira kumunda wese wakasvikwa. Zvidzidzo zvemazuva ano zvekuongorora zvinotsanangura zvakajeka kuti mwaranzi yeaperture uye diffraction yeflange-edge pakuverenga maitiro efar-field.
Kuwedzera saizi yevhu rinoita basa kunogona kupa kutungamira kwakanyanya uye danda guru rakatetepa, ndicho chimwe chezvikonzero nei maantenna ehorn uye zvivakwa zvakakura zvevhu zvichiwanzo shandiswa kana paine kuwedzera kwakanyanya.

5. Mhando Huru dzeAperture Antennas
Antena yeMafungu Akavhurika
Guide yemagetsi inovhurika ndeimwe yema radiator ari nyore kushandisa. Maumbirwo ayo akapfava uye kuenderana kwayo zvakananga nema waveguide system kunoita kuti ishande mu microwave ne millimeter-wave laboratories, antenna measurements, probes, feeds, nedzimwe RF systems.
Antena yenyanga
Antena yenyanga inogona kuonekwa senzira yekufambisa mafungu ine chikamu chinotambanuka zvishoma nezvishoma ichienda kuburi rinopenya. Kuchinja uku zvishoma nezvishoma kunovandudza shanduko kubva kumafungu anotungamirwa kuenda kumwaranzi yemuchadenga uye kunogona kupa kuenderana kuri nani kweimpedance, kuwedzera kwekuwedzera, uye mapatani emwaranzi anodzorwa zvakanyanya.
Maantenna enyanga anoshandiswa zvakanyanya mukuyera maantenna, EMC testing, radar, communication systems, feed systems, uye millimeter-wave applications.
Kanyanga yeSlot
Antena yeslot inoshandisa mukana kana kuti slot yakachekwa pamusoro pe conduction kuti ibudise simba remagetsi. Zvichienderana nejometri yeslot, excitation, uye chimiro chakakomberedza, ma slot antenna anogona kuiswa ega kana kusanganiswa kuita arrays.
Dzinoshandiswa zvakanyanya muma microwave systems uko kunodiwa ma structures asina kunyatsojeka, kubatanidzwa, kana array configurations.
6. MaAntenna eAperture muRF neMicrowave Engineering
Nekuti ma aperture antennas anobatanidzwa zvakasikwa ne waveguide transmission structures, anonyanya kukosha pama microwave nema millimeter-wave frequency.
Maitiro akajairika anosanganisira:
- Kuyerwa kwekuwedzera kweantena uye mapatani emwaranzi
- Kuongororwa kweEMC neEMI
- Masisitimu eradar
- Kutaurirana kwema microwave nema millimeter-wave
- Masisitimu ekudyisa maAntena
- Kuyerwa kweRF murabhoritari
- Kutumirwa kwekutungamira uye kugamuchira
- Masisitimu ekuyedza uye ekugadzirisa
Kune mainjiniya eantenna, kusarudza aperture antenna yakakodzera kunoda zvinopfuura kungofunga nezve frequency. Ma parameter akadai se gain, beamwidth, polarization, VSWR, waveguide size, flange type, power handling, uye mechanical dimensions zvese zvinogona kukanganisa mashandiro esystem.
Mhedziso
Maantenna eAperture anopa nzira inoshanda yekushandura simba remagetsi rinotungamirwa kuita mwaranzi yemuchadenga, zvichiita kuti ave chikamu chakakosha cheantenna mu microwave uye millimeter-wave engineering.
Kubva pama waveguides akareruka ane magumo akavhurika kusvika kuma optimized horn uye slot structures, aperture antennas anogona kugadzirwa kuti akwanise kusanganisa zvakasiyana-siyana zve gain, beamwidth, polarization, frequency range, uye system integration.
Kunzwisisa kuti saizi yeaperture, kugoverwa kwesimba remagetsi, ma waveguide modes, uye zvivakwa zvakakomberedza zvinokanganisa sei mashandiro emwaranzi, saka zvakakosha pakusarudza kana kugadzira ma antenna eRF testing, communication, radar, uye measurement systems.
