Antena ya RM-SGHA10-25 Standard Gain Horn ya Mapulogalamu a W-Band a 75–110 GHz

Kugwira Ntchito Molondola Kwambiri pa Kuyeza kwa W-Band RF

Pa ma frequency a millimeter-wave, gawo lililonse mu unyolo woyezera ndi lofunika. Kusagwirizana pang'ono kwa impedance, mawonekedwe osakhazikika a radiation, kapena zigawo zosafunikira za polarization zimatha kusintha mwachangu kulondola kwa mayeso.RF MISOAntena ya RM-SGHA10-25 Standard Gain Hornyapangidwa kuti igwiritsidwe ntchito m'mapulogalamu onse75 mpaka 110 GHz, kupereka yankho la antenna lokhazikika komanso lolunjika bwino kwa mainjiniya omwe amagwira ntchito mu W-band.

Yomangidwa mozunguliramawonekedwe a WR10 waveguide, RM-SGHA10-25 imaphatikiza kufalikira kwa ma frequency ambiri ndi25 dBi phindu lachizolowezindi1.1:1 VSWR yachizoloweziKuphatikiza kumeneku kumathandiza kupereka mphamvu ya RF yogwira mtima komanso kusunga chitsogozo champhamvu pa ntchito yonse. Antena imagwiritsa ntchitokugawanika kwa mzerendipo imafotokoza50 dB cross-polarization isolation, kuthandizira miyeso pomwe kusiyanitsa kwa polarization ndi gawo lofunikira pa magwiridwe antchito a dongosolo.

Kuwongolera Kwambiri Kudutsa 75–110 GHz

Honi yodziwika bwino ya gain horn imakhala yofunika kwambiri ngati mphamvu yake ya radiation ikupitirira kudziwika bwino pamene mafunde akusintha. Deta yoyeserera imaperekedwa kwaRM-SGHA10-25Mawonetsero akuchulukirachulukira pang'onopang'ono kudutsa gulu lonse, kuyambira pafupifupi pakati pa 25 dBi kumapeto otsika mpaka kupitirira 27 dBi pafupi ndi 110 GHz.

Khalidwe limeneli la mbali limawonekeranso m'mawonekedwe a kuwala.75 GHz, 92.5 GHz, ndi 110 GHz, mapangidwe oyeserera amasunga kuwala kwakukulu komveka bwino, pomwe kuwala kumakhala kocheperako pamene ma frequency akuwonjezeka. Ma 3 dB beamwidth values ​​omwe anenedwa akuwonetsa kupita patsogolo kumeneku, kupatsa mainjiniya deta yothandiza poyesa mawonekedwe a angular, zofunikira pakulinganiza, ndi mawonekedwe a muyeso.

Kuwunikira Kochepa kwa Maunyolo Oyezera Oyera

Pa ma frequency a W-band, kufananiza bwino kwa impedance kumakhala kofunikira kwambiri chifukwa kutayika ndi kuwunikira kumatha kukhudza mosavuta kusatsimikizika konse kwa muyeso.

RM-SGHA10-25 yatchulidwa ndiVSWR yachizolowezi ya 1.1:1, ndipo kalembedwe ka ma simulation mu datasheet kamakhalabe pafupi ndi mgwirizano mu 75–110 GHz yonse. Khalidwe locheperako lowunikira limathandiza kuchepetsa zotsatira zosafunikira za mafunde oyima ndipo limalola mphamvu zambiri za RF zomwe zilipo kuti zifike pa antenna aperture.

Pa makina oyesera a labotale ndi ma millimeter-wave, izi zikutanthauza kuti antenna ikhoza kugwira ntchito ngati chinthu chokhazikika chowunikira kapena cholandira komwe kubwerezabwereza ndi machitidwe olamulidwa a RF ndizofunikira.

Kuyera Kwambiri kwa Polarization

Kapangidwe ka antenna kokhala ndi polarization yolunjika kamathandizidwa ndi kusungunuka kwakukulu kwa polarization. Mndandanda wazinthu zomwe zafotokozedwa50 dB cross-polarization isolation, pomwe deta yotsanzira yomwe ili m'munsiyi imapereka chidziwitso chowonjezera pa kusiyana kwa polarization pakati pa gulu logwira ntchito.

Kupatula kwa polarization yayikulu ndikofunikira kwambiri pamene mainjiniya akufunika kusiyanitsa gawo lofunikira la polarization ndi mphamvu yosafunikira ya orthogonal. M'malo mongoyang'ana pa gain yokha, mawonekedwe owonjezerawa amapereka chithunzi chokwanira cha magwiridwe antchito a antenna mu miyeso yolondola ya RF.

Yaing'ono, Yopepuka Ndipo Yopangidwira Kuphatikiza kwa Millimeter-Wave

Ngakhale kuti imagwira ntchito pafupipafupi kwambiri, RM-SGHA10-25 imakhalabe yaying'ono. Kapangidwe ka mtundu wa C kamayesa pafupifupi82.5 × 26.09 × 33.68 mmndipo zimalemera zokha0.03 kgKapangidwe kake ka mkuwa ndikumaliza kokutidwa ndi golideimaphatikiza kuyendetsa magetsi ndi kapangidwe ka akatswiri ka mafunde a millimeter.

Tsamba la deta limasonyezanso ma waveguide/flange komanso ma connector-interface configuration, zomwe zimapatsa mainjiniya kusinthasintha kowonjezera akamaphatikiza antenna mu ma RF setups osiyanasiyana.

Ndi zakeKuphimba kwa 75–110 GHz, 25 dBi wamba, VSWR yotsika, kusiyanitsa kwamphamvu kwa polarization, ndi kapangidwe kakang'ono ka WR10,RM-SGHA10-25imapereka yankho lolondola komanso lothandiza la gain horn pa malo ovuta a W-band RF ndi antenna.
