Antena ya nyangandiantenna iwiri yozunguliraNdi mitundu iwiri ya ma antenna omwe amagwiritsidwa ntchito m'magawo osiyanasiyana chifukwa cha makhalidwe awo apadera komanso ntchito zawo. M'nkhaniyi, tifufuza makhalidwe a ma antenna a horn ndi ma antenna okhala ndi polarized awiri ndikufufuza momwe ma antenna awa amagwiritsidwira ntchito nthawi zambiri.
Antena ya Horn ndi antenna yolunjika yomwe imagwiritsidwa ntchito kwambiri mumakina olumikizirana a maikulowevu ndi ma wailesi. Amadziwika ndi mawonekedwe a conical kapena pyramidal, omwe amawalola kuti azitha kutulutsa bwino ndikulandira mafunde amagetsi. Antena za Horn zimapangidwa kuti zikhale ndi bandwidth yayikulu komanso phindu lalikulu, zomwe zimapangitsa kuti zikhale zoyenera kulumikizana kwakutali komanso machitidwe a radar.
Kumbali inayi, antenna yokhala ndi polarized dual-polarized ndi antenna yomwe imatha kutumiza ndikulandira mafunde a wailesi m'ma polarizations awiri ozungulira nthawi imodzi. Izi zikutanthauza kuti imatha kuthana ndi polarization yopingasa komanso yoyima, motero imawonjezera mphamvu ya data ndi khalidwe la chizindikiro m'makina olumikizirana.
Chimodzi mwa zinthu zofunika kwambiri zomwe zimagwiritsidwa ntchito popanga ma antenna a horn ndi ma radar system. Chifukwa cha kuchuluka kwa ma antenna awo komanso momwe amagwirira ntchito, ma horn antenna amagwiritsidwa ntchito kwambiri poika ma radar kuti aziwongolera kayendedwe ka ndege, kuyang'anira nyengo, komanso kuyang'anira asilikali. Kutha kwawo kutumiza ndikulandira mafunde amagetsi molondola patali kumawapangitsa kukhala gawo lofunikira la ukadaulo wa radar.
Kuwonjezera pa makina a radar, ma antenna a horn amagwiritsidwanso ntchito polumikizirana ndi ma satellite. Kuchuluka kwa ma bandwidth ndi kuchuluka kwa ma antenna a horn kumapangitsa kuti akhale oyenera kutumiza ndi kulandira zizindikiro kuchokera ku ma satellite mumlengalenga. Kaya ndi kuwulutsa pa wailesi yakanema, kulumikizana ndi intaneti kapena makina oyika zinthu padziko lonse lapansi, ma antenna a horn amagwira ntchito yofunika kwambiri pakukhazikitsa maulalo odalirika olumikizirana ndi ma satellite.
Kuphatikiza apo, ma antenna a horn amagwiritsidwa ntchito kwambiri mu makina olumikizirana opanda zingwe monga ma microwave links a point-to-point ndi ma network a m'deralo opanda zingwe (WLANs). Kuwongolera kwawo komanso kuchuluka kwawo kumapangitsa kuti akhale abwino kwambiri pokhazikitsa maulumikizidwe opanda zingwe akutali, makamaka m'matauni ndi m'midzi komwe kulumikizana kwa mzere ndikofunikira kwambiri.
RFMISOMalangizo a Mndandanda wa Mankhwala a Horn Antenna:
RM-SGHA430-15（1.70-2.60GHz）
RM-BDHA618-10 (6-18GHz)
RM-CDPHA3337-20 (33-37GHz)
Ponena zama antenna okhala ndi polarized awiri, nthawi zambiri amagwiritsidwa ntchito m'machitidwe olumikizirana opanda zingwe omwe amafunikira kufalikira kwa deta yambiri komanso kudalirika kwa zizindikiro. Mwachitsanzo, m'ma netiweki am'manja, ma antenna okhala ndi polarized awiri amagwiritsidwa ntchito kukulitsa mphamvu ndi magwiridwe antchito a malo oyambira pothandizira kutulutsa kwa multiple-input multiple-output.Ukadaulo wa (MIMO)Mwa kutumiza ndi kulandira zizindikiro mu ma polarizations awiri ozungulira, ma antenna okhala ndi ma polarized awiri amatha kusinthana deta nthawi imodzi, zomwe zimapangitsa kuti ma spectral agwire bwino ntchito komanso kuti ma network azitha kugwira ntchito bwino.
Kuphatikiza apo, ma antenna okhala ndi polarized awiri ndi zinthu zofunika kwambiri pa wailesi zakuthambo ndi ntchito zowunikira kutali. Amatha kujambula mafunde a wailesi okhala ndi polarized mopingasa komanso molunjika, zomwe zimathandiza kuzindikira ndi kusanthula bwino zochitika zakuthambo ndi zachilengedwe. Mu wailesi zakuthambo, ma antenna okhala ndi polarized awiri amagwiritsidwa ntchito pophunzira momwe magwero a zakuthambo amagwirira ntchito, zomwe zimapatsa chidziwitso chofunikira pa chikhalidwe cha zinthu zakuthambo ndi chilengedwe.
Pankhani yofalitsa nkhani popanda zingwe, ma antenna okhala ndi ma polarized awiri amagwiritsidwa ntchito pofalitsa nkhani pa wailesi yakanema ndi wailesi. Pogwiritsa ntchito ma antenna okhala ndi ma polarized awiri, ofalitsa nkhani amatha kugwiritsa ntchito bwino ma radio spectrum ndikuwongolera ubwino wa ma signali owulutsa, zomwe zimapangitsa kuti owonera azimva bwino komanso azimva bwino.
RFMISOMalangizo a mndandanda wazinthu za antenna za nyanga ziwiri zozungulira:
RM-DPHA6090-16 (60-90GHz)
RM-CDPHA3238-21（32-38GHz）
RM-BDPHA083-7（0.8-3GHz）
Mwachidule, ma antenna a horn ndi ma antenna okhala ndi polarized awiri ndi zinthu zofunika kwambiri pa ntchito zosiyanasiyana kuphatikizapo radar systems, satellite communications, wireless networks, radio astronomy ndi Broadcasting. Makhalidwe awo apadera ndi luso lawo zimapangitsa kuti zikhale zofunika kwambiri pakupanga maulalo odalirika komanso ogwira mtima komanso kupititsa patsogolo kafukufuku wa sayansi ndi luso lamakono. Pamene kufunikira kwa ma antenna ogwira ntchito bwino kukupitirira kukula, kufunika kwa ma antenna a horn ndi ma antenna okhala ndi polarized awiri pakulankhulana kwamakono ndi ntchito zasayansi kukuyembekezeka kukhalabe kofunika kwambiri.
Kuti mudziwe zambiri zokhudza ma antenna, chonde pitani ku:
