Momwe Mungasankhire Wopanga Ma Antena a Horn Yawiri Yoyesera Broadband RF

Kusankhawopanga ma antenna a nyanga ziwiriSikuti ndi nkhani yongoyerekeza ma frequency ranges okha. Pa kuyesa kwa broadband RF, antenna iyeneranso kupereka kufananiza kokhazikika kwa impedance, machitidwe odziwikiratu a radiation, zolumikizira zoyenera, ndi miyeso yamakina yomwe ikugwirizana ndi momwe mungayikitsire. Zambirizi zimakhudza mwachindunji kubwerezabwereza mu kuyesa kwa EMC/EMI, kuyeza kwa antenna, kuyang'anira chizindikiro, ndi kuphatikiza kwa makina.

RF MISO imapanga ndikupereka mayankho a ma antenna a nyanga ya broadband kwa mainjiniya a RF, ophatikiza makina, ma laboratories, ndi opanga zida. Mitundu yoyimira pansipa yonse ikuphatikizapo0.4 mpaka 40 GHz, zomwe zimathandiza ogwiritsa ntchito kusankha antenna ya gulu logwirira ntchito lomwe lafotokozedwa m'malo moganiza kuti antenna imodzi imaphimba gawo lonse.

Chifukwa Chake Ma Antenna Awiri Okhala ndi Mizere Yawiri Amagwiritsidwa Ntchito Poyesa Broadband RF

Kapangidwe ka mafunde ozungulira kawiri kamakulitsa bandwidth yogwiritsidwa ntchito ya antenna ya horn pomwe imasunga kuwala kolunjika ndi polarization yolunjika. Kuphatikiza kumeneku kumapangitsa antenna kukhala yothandiza pamene makina oyesera ayenera kugwira ntchito pamlingo waukulu popanda kusintha mobwerezabwereza ma antenna.

Kugwiritsa ntchito kwanthawi zonse kumaphatikizapo kuyesa kutulutsa mpweya woipa, kuwunika kwa EMC/EMI, kuyeza kuchuluka kwa antenna ndi mawonekedwe a radiation, kutumiza ndi kulandira chizindikiro cha broadband, kuyang'anira, kufufuza, ndi kupeza komwe chikupita. Mtundu wabwino kwambiri umadalirabe band yofunikira, kuchuluka komwe mukufuna, mtunda woyesera, malo omwe alipo, mawonekedwe olumikizira, ndi mulingo wamagetsi.

Zoyenera Kuwunika Posankha Wopanga

1. Kuphimba pafupipafupi kutengera gulu lenileni la mayeso

Yambani ndi ma frequency otsika komanso apamwamba kwambiri ogwirira ntchito omwe amafunikira ndi makinawa. Kuchuluka kwa ma antenna sikuli bwino kokha: antenna yosankhidwa iyenera kufanana ndi gulu loyesera lenilenilo pamene ikukwaniritsa zofunikira za gain, beamwidth, kukula, ndi mikhalidwe yolumikizira. Ngati pali ma band angapo, yerekezerani kusiyana pakati pa mtundu umodzi wa broadband ndi ma antenna angapo okonzedwa kuti akhale ndi ma ranges ochepa.

2. Kufananiza phindu ndi impedance

Mphamvu ya phindu imagwirizanitsa bajeti ndi mphamvu yamunda, pomwe VSWR imasonyeza momwe mphamvu imasamutsidwira bwino pakati pa mzere wodyetsa ndi antenna. Mitengo yofalitsidwa iyenera kuwerengedwa pamodzi ndi ma grafu odalira pafupipafupi nthawi iliyonse ikatheka. Mainjiniya a RF ayeneranso kutsimikizira ngati mitengo yomwe yatchulidwa ndi yofanana kapena yotsimikizika ndikuwunikanso deta yomwe ilipo kuti mudziwe momwe imagwiritsidwira ntchito.

3. Kugwira ntchito kwa radiation ndi polarization

Kuphimba kwa broadband kokha sikumatanthauzira magwiridwe antchito a antenna. Mawonekedwe a radiation, beamwidth, cross-polarization isolation, ndi linear polarization direction zingakhalenso zofunika kwambiri mu njira zoyezera ndi kuyang'anira. Makhalidwe amenewa amathandiza kudziwa momwe mayeso amayendera, zofunikira pakugwirizana, komanso kusatsimikizika kwa muyeso.

4. Kulumikizana kwa cholumikizira ndi makina

Mtundu wa cholumikizira uyenera kugwirizana ndi ma frequency ogwiritsira ntchito, kusonkhana kwa chingwe, ndi zida zoyesera. Miyeso yonse, kulemera, kapangidwe ka malo oikira, ndi momwe antenna imayendera zimakhudzanso kuyika kwa chipinda, makina oikira, ndi makonzedwe oyesera onyamulika. Kujambula kwa makina komwe kulipo ndikofunikira kwambiri pamene antenna iphatikizidwa mu cholumikizira kapena nsanja yomwe ilipo.

5. Zolemba za wopanga ndi kulumikizana kwaukadaulo

Wopereka ma antenna anzeru a broadband horn ayenera kupereka ma specifications a mtundu wa antenna komanso kulankhulana bwino kwaukadaulo. Musanayitanitse, gawani kuchuluka kwa ma frequency ofunikira, kugwiritsa ntchito, kupeza cholinga, cholumikizira, mulingo wa mphamvu, zoletsa zomangira, ndi momwe zinthu zilili. Izi zimapatsa wopanga chidziwitso chokwanira kuti awone ngati mtundu wamba ndi woyenera.

Woyimira RF MISO Broadband Horn Antennas

RM-BDHA046-10Cholinga chake ndi kugwira ntchito kwa broadband yocheperako kuyambira 0.4 mpaka 6 GHz ndipo ili ndi phindu la 10 dBi. Mafotokozedwe ake apano amatchula polarization yolunjika, 30 dB cross-polarization isolation, cholumikizira chachikazi cha SMA, ndi mphamvu yogwiritsira ntchito mphamvu yapakati ya pafupifupi 500 W.

RM-BDHA118-10Imaphimba 1 mpaka 18 GHz ndi 10 dBi. Kukula kwake kochepa kumapangitsa kuti ikhale yoyenera kugwiritsa ntchito makina a labu ya wideband komwe kumafunika kuphimba kudzera mu microwave range.

RM-BDHA440-13Imakulitsa kufalikira kwa magetsi kuyambira 4 mpaka 40 GHz ndi 13 dBi yowonjezera. Kapangidwe kameneka kamapereka cholumikizira cha 2.92 mm Chachikazi kapena 2.4 mm Chachikazi ndipo chimalemera 33 g, chomwe chikuthandizira ntchito zoyezera pafupipafupi komanso zophatikizana pomwe kukula kochepa ndikofunikira.

Mafotokozedwe omwe ali pamwambapa akuchokera pa ma datasheet a mtundu wamakono omwe aperekedwa poyerekezera uku. Tsimikizani datasheet yaposachedwa komanso momwe mukufunira ndi RF MISO musanayitanitse.

Kugwira ntchito ndi RF MISO ngati Wopanga Ma Antena

RF MISO imaphatikiza kafukufuku ndi chitukuko cha ma antenna, uinjiniya, kupanga, ndi malonda mkati mwa bungwe limodzi. Kwa ogula mainjiniya, kulumikizana mwachindunji kwaukadaulo kumathandiza kulumikiza zofunikira pakugwiritsa ntchito ndi mtundu winawake ndi zolemba zomwe zilipo. RF MISO imapereka ma antenna a RF ndi ma microwave application, kuphatikiza ma antenna a broadband horn, ma antenna a standard gain horn, ma antenna a corrugated horn, ma antenna a waveguide, ndi mayankho ena a antenna.

Mukalumikizana ndi RF MISO, perekani kuchuluka kwa ma frequency ogwiritsira ntchito, mayeso kapena pulogalamu yomwe mukufuna kugwiritsa ntchito, cholumikizira chomwe mukufuna, cholinga chopezera, mphamvu yofunikira, malire okwezera, ndi deta iliyonse yofunikira yoyezera. Gulu laukadaulo likhoza kuwonanso mitundu yomwe ilipo ndikuthandizira kupeza poyambira yoyenera.

Mafunso Ofunsidwa Kawirikawiri

Kodi kusiyana pakati pa nyanga yokhala ndi mizere iwiri ndi nyanga yodziwika bwino yopeza phindu ndi kotani?

Nyanga yokhala ndi mizere iwiri nthawi zambiri imasankhidwa kuti igwiritsidwe ntchito pafupipafupi. Nyanga yodziwika bwino ya gain horn nthawi zambiri imagwiritsidwa ntchito pamwamba pa gulu lopapatiza la waveguide pamene pakufunika kufotokozedwa bwino kwa gain reference. Kusankha kolondola kumadalira bandwidth, gain, pattern, njira yoyesera, ndi zofunikira pakuyesa.

Kodi antenna imodzi ya RF MISO ingaphimbe ma GHz 0.4 mpaka 40?

Ayi. Chithunzi cha 0.4–40 GHz chikufotokoza momwe mitundu yoyimira imagwirira ntchito m'nkhaniyi imagwirira ntchito. Antena iliyonse ili ndi bande yake yogwirira ntchito, kotero ogwiritsa ntchito ayenera kusankha mtundu kutengera kuchuluka kwa ma frequency awo enieni.

Ndi chidziwitso chiti chomwe ndiyenera kutumiza kwa wopanga ma antenna a horn?

Perekani ma frequency ocheperako komanso apamwamba, kugwiritsa ntchito, kufunikira kwa kukwera, polarization, cholumikizira, mulingo wamagetsi, malo oyika, njira yoyikira, ndi deta iliyonse yoyesera yofunikira. Zofunikira zonse zimachepetsa zolakwika posankha ndikufulumizitsa kuwunika kwaukadaulo.

Ndi mtundu uti womwe ndiyenera kusankha poyesa ma wideband?

Yankho limadalira gulu ndi momwe zimakhalira. Ma adilesi a RM-BDHA046-10 ndi 0.4–6 GHz, RM-BDHA118-10 ndi 1–18 GHz, ndipo RM-BDHA440-13 ndi 4–40 GHz. Gain, connector, miyeso, mphamvu, ndi radiation ziyeneranso kuunikidwanso musanasankhe.
