Antena ya Horn ya RM-DCPHA12-10 Yozungulira Yozungulira ya 1–2 GHz RF Applications

Mu makina apamwamba a RF, magwiridwe antchito a antenna samadziwika ndi phindu lokha. Kusinthasintha kwa polarization, kufananiza impedance, kuyera kwa radiation, kudzipatula kwa kutsogolo ndi kumbuyo, ndi kuthekera kogwiritsa ntchito mphamvu zonse zimakhudza kudalirika kwa muyeso kapena kulumikizana. RF MISO'sRM-DCPHA12-10Wapawiri Zozungulira Polarization Horn Antennaimabweretsa zofunikira izi pamodzi mu yankho laukadaulo la antenna lomwe limaphimbaMafupipafupi a 1–2 GHz.

Yopangidwa kuti igwire ntchito yozungulira iwiri,RM-DCPHA12-10imagwirizana bwino ndi makina omwe kuwongolera polarization ndikofunikira kapena komwe kulumikizana pakati pa ma antenna otumizira ndi olandira kungasinthe. Polarization yozungulira ingathandize kuchepetsa kukhudzidwa ndi kulumikizana kwa ma antenna ndikuthandizira kulandira chizindikiro chokhazikika m'malo ovuta kufalikira. Mphamvu ya polarization yozungulira iwiri imapatsanso mainjiniya kusinthasintha kwakukulu poyesa magwiridwe antchito a makina odalira polarization.

Antena imapereka10 dBi phindu lachizolowezi, kupereka malangizo othandiza poyesa RF, kuyang'anira zizindikiro, kuyeza antenna, kupeza njira, ndi kuphatikiza makina. Zotsatira za kuyeserera zikuwonetsa kuyankha bwino kwa kukwera kwa magetsi kudutsa gulu logwirira ntchito, ndipo kuwala kwa radiation kumachepa pang'onopang'ono pamene ma frequency akuwonjezeka. Khalidwe lodziwikiratu ili ndi lofunika kwambiri poyesa labotale, kuyeza kofananira, ndi kugwiritsa ntchito njira za RF komwe kumafunika kuwongolera nthawi zonse kwa kuwala.

Kusamutsa chizindikiro bwino kumathandizidwa ndiVSWR yachizolowezi ya 1.3:1Ma curve a VSWR oyeserera amitundu iwiri ya polarization amakhalabe ofanana kwambiri pa gulu la 1-2 GHz, zomwe zimathandiza kuchepetsa mphamvu yowunikira ndikupitiliza kugwira ntchito bwino. Antena iyi imaperekanso40 dB magwiridwe antchito a cross-polarization, kuthandizira kuyera kwamphamvu kwa polarization komanso kulekanitsa bwino pakati pa zigawo zomwe zimafunidwa ndi zomwe sizikufunidwa.

A Chiŵerengero cha 50 dB chaching'ono cha kutsogolo ndi kumbuyokumalimbitsanso magwiridwe antchito a mbali mwa kuchepetsa kuwala komwe kumapita kumbuyo kwa antenna. Khalidweli ndi lothandiza makamaka pamitundu yoyesera ma antenna, kuzindikira EMI, kuzindikira, njira zopezera malangizo, ndi ntchito zowunikira komwe zizindikiro zochokera ku malangizo osafunikira zingakhudze kulondola kwa muyeso.

Kuti zigwirizane ndi zofunikira zosiyanasiyana za mphamvu ndi mawonekedwe a makina, RM-DCPHA12-10 ikupezeka m'mitundu iwiri.RM-DCPHA12-10Simagwiritsa ntchito mawonekedwe a SMA-Female ndipo imathandiziraMphamvu ya mafunde osalekeza a 50 W, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito m'ma laboratories ndi m'mayeso.RM-DCPHA12-10NIli ndi mawonekedwe a N-Female ndipo imathandizira mpakaMphamvu ya mafunde osalekeza a 500 Wkuti mupeze malo ovuta kwambiri otumizira mauthenga ndi mayeso.

Wopangidwa ndi aluminiyamu yokhala ndi utoto wakuda, antenna iyi imaphatikiza mphamvu ya makina ndi mawonekedwe aukadaulo a mafakitale. Miyeso yake yonse ndi pafupifupi334.0 × 214.1 × 224.4 mm, ndi kulemera kwamakilogalamu 3.163, zomwe zimathandiza kuti pakhale njira yosavuta yolumikizirana ndi mapulatifomu oyesera okhazikika, makina oyika zinthu, ma antenna ranges, ndi zida zapadera za RF.

Ntchito zomwe zimagwiritsidwa ntchito nthawi zambiri zimaphatikizapo:

• Kuzindikira EMI ndi kuyesa kwamagetsi
• Kupeza njira ndi kuyang'ana chizindikiro
• Kuwunikanso ndi kuyang'anira RF
• Kuyerekeza kwa phindu la ma antenna
• Kuyeza kwa njira ya radiation
• Kuyankhulana ndi kuwunika kwa makina a radar
• Kuyesa kwamphamvu kwa RF komanso kuphatikiza kwa makina

Ndi kufalikira kwake kwakukulu kwa 1–2 GHz, polarization yozungulira iwiri, stable gain, VSWR yotsika, kuyera kwa polarization yayikulu, magwiridwe antchito abwino kwambiri kutsogolo ndi kumbuyo, komanso mawonekedwe ake amphamvu kwambiri,Antena ya Horn ya RM-DCPHA12-10 Yozungulira Yozunguliraimapereka njira yodalirika komanso yodalirika yoyezera RF ndi njira zolumikizirana za akatswiri.
