Antena ya RM-CGHA28-15 Linear Polarization Corrugated Horn ya 26.5–40 GHz Millimeter-Wave Applications

Kwa mainjiniya omwe amagwira ntchito ndi ma RF ndi ma millimeter-wave systems omwe amagwira ntchito pafupipafupi, magwiridwe antchito a antenna samangokhudza kupeza mphamvu zokha. Kulamulira kwa denga, kuyera kwa polarization, kufananiza impedance, ndi kusinthasintha kwa integration kungakhale kofunikira.RF MISO RM-CGHA28-15 Linear Polarization Corrugated Horn Antennaidapangidwa kuti ikwaniritse zofunikira izi m'njira zosiyanasiyanaMafupipafupi a 26.5–40 GHz, zomwe zimapangitsa kuti ikhale yankho lothandiza pa njira zamakono zoyezera, kulankhulana, komanso kugwiritsa ntchito radar.

Ndi15 dBi phindu lachizolowezindi1.2 VSWR wamba, RM-CGHA28-15 imapereka kuphatikiza kwamphamvu kwa kuwala kolunjika komanso kufananiza bwino kwa RF. Ndi yachizoloweziM'lifupi mwa 3 dB ndi 26° mu E-plane ndi 25° mu H-plane., kuthandiza kupanga kuwala kotsogola koyendetsedwa bwino kwa ntchito zomwe zimafunika kuti munthu azitha kuona bwino momwe kuwalako kumaonekera. Antena imatchulanso mulingo wocheperako wa mbali ya25 dB mu ndege ya E ndi 30 dB mu ndege ya Hpamodzi ndi40 dB magwiridwe antchito a cross-polarization.

Zotsatira za kuyeserera zikuwonetsanso momwe antenna imagwirira ntchito pa intaneti. Kudzera mu ntchito, kuchuluka kwa maginito kumakwera kuchoka pa 15 dB kumapeto kwa band kufika pa 18 dB pafupi ndi 40 GHz, pomwe VSWR yoyeserera imakhalabe yotsika kuposa maginito ambiri. Kugwira ntchito kwa XPD koyeserera kumakhalabe pamlingo wapamwamba pama frequency oyesedwa, kuthandizira mapulogalamu omwe amapindula ndi kusankhana kwabwino kwa linear-polarization.

Kusinthasintha kwa kuphatikiza ndi ubwino wina waukulu. RM-CGHA28-15 imapezeka m'makonzedwe awiri:Mtundu wa Camagwiritsa ntchitoChitsogozo cha mafunde cha WR28 chokhala ndi flange ya UG-599/U, pomweMtundu wa FimaperekaChiwonetsero cha coaxial chachikazi cha 2.92 mmIzi zimathandiza mainjiniya kusankha mtundu womwe ukugwirizana bwino ndi zida zawo zoyesera zomwe zilipo kapena kapangidwe ka makina a RF. Mabaibulo onsewa amagwiritsa ntchitokapangidwe ka mkuwa kokutidwa ndi golide, pamene ikusunga mawonekedwe a makina opapatiza komanso opepuka.

NdiMphamvu yogwiritsira ntchito mphamvu ya 20 W CW ndi 40 W peak, RM-CGHA28-15 imagwirizana bwino ndi malo osiyanasiyana a RF omwe amayendetsedwa pafupipafupi. Malinga ndi zomwe zafotokozedwa mu malonda, ntchito zomwe zimagwiritsidwa ntchito nthawi zambiri zimaphatikizapoMakina a 5G ndi ma millimeter-wave, makina a radar, ndi mauthenga a satellite.

Kwa ma laboratories, ophatikiza machitidwe, ndi mainjiniya a RF omwe akufuna compactAntena ya nyanga ya 26.5–40 GHz yokhala ndi corrugated hornNdi mawonekedwe olamulidwa a beam, njira zingapo zolumikizirana ndi RF, komanso magwiridwe antchito amphamvu a polarization, RM-CGHA28-15 imapereka nsanja yosinthika yoyesera pafupipafupi komanso kuphatikiza makina.
