Mu makina olumikizirana a microwave, kuchuluka kwa ma antenna ndi chizindikiro chofunikira choyezera momwe kuwala kumagwirira ntchito. Monga katswiriwogulitsa ma antenna a microwave, tikudziwa bwino kufunika kowerengera molondola ndikuyesa kuchuluka kwa antenna kuti makina azitha kugwira ntchito bwino. Nkhaniyi ifotokoza zaAntena ya 40GHzndiKasegrain antennamonga zitsanzo zofotokozera mwatsatanetsatane njira yowerengera ndi mfundo zothandiza za kupeza antenna.
1. Maziko a kuwerengera kwa chiphunzitso
Kupeza ma antenna (dBi) kumatsimikiziridwa ndi kuwongolera ndi magwiridwe antchito:
Kupeza (dBi) = chitsogozo × magwiridwe antchito
1. Kuwerengera kwa malangizo:
Ma antenna amphamvu kwambiri (monga ma antenna a Cassegrain) akapezeka pophatikiza mawonekedwe a radiation, amatha kuyika mphamvu mu kuwala kopapatiza.
2. Zinthu zofunika kuziganizira pakugwiritsa ntchito bwino ntchito:
Zinthu zotsatirazi zotayika ziyenera kuganiziridwa:
- Kutayika kwa feeder (monga kusalingana kwa katundu wa waveguide)
- Kutayika kwa zinthu
- Kulondola kwa kukonza pamwamba
2. Njira zoyezera zaukadaulo
1. Njira yoyesera yoyerekeza:
Yerekezerani antenna yomwe ikuyesedwa (monga antenna ya 40GHz) ndi antenna yodziwika bwino ya gain horn.
2. Mayeso akutali:
Yesani mawonekedwe a kuwala kwa dzuwa mu chipinda chamdima cha microwave, chomwe ndi njira yoyesera yaukadaulo yomwe imagwiritsidwa ntchito kwambiri ndi ogulitsa ma antenna.
3. Mayeso a network analyzer:
Unikani kutayika kobwerera ndi mphamvu ya kuwala kudzera mu kusanthula kwa magawo a S.
Antena ya Broadband Horn(18-40GHz)
Chitsogozo cha Waveguide kupita ku Coaxial Adapter (26.5-40GHz)
Antena Yofufuzira ya Waveguide(26.5-40GHz)
RFmiso40Ghz Antenna Products
3. Ukadaulo wotsimikizira kuyeserera
Gwiritsani ntchito mapulogalamu aukadaulo oyeserera zamagetsi monga HFSS ndi CST:
- Yerekezerani molondola momwe aperture imagwirira ntchito (makamaka yofunika kwambiri pa **Cassegrain antenna** ndi ma antenna ena owonetsa)
- Unikani momwe chakudya chilili
- Unikani momwe ** imakhudzirachitsogozo cha mafundekatundu**
4. Mfundo zazikulu za uinjiniya
1. Makhalidwe a pafupipafupi:
Kuchuluka kwa ma antenna kuli ndi mgwirizano wofunikira kwambiri (monga kuchuluka kwa ma antenna a 40GHz kudzachepa pa 30GHz).
2. Zinthu zokhudzana ndi chilengedwe:
Malo oyika, kusokoneza kozungulira, ndi zina zotero zidzakhudza momwe zinthu zilili.
3. Zofunikira pa ndondomeko:
Kukonza zinthu mwanzeru kumatsimikizira kuti kapangidwe ka mfundo kakhoza kukwaniritsidwa.
Antena ya Cassegrain (26.5-40GHz)
Upangiri wa akatswiri:
Pazofunikira zapadera monga antenna ya **40GHz** mu millimeter wave band kapena antenna ya **Cassegrain** yokhala ndi phindu lalikulu, tikukulimbikitsani kugwirizana ndi katswiri wopereka antenna ya **microwave** yemwe ali ndi luso loyesera mokwanira kuti atsimikizire kuti malonda akugwira ntchito bwino.
Tili ndi:
- Chipinda chonse choyesera
- Gulu la akatswiri oyeza
- Chidziwitso chochuluka cha uinjiniya
Kuti mupeze njira zina zowonjezerera mphamvu ya antenna, chonde musazengereze kulankhulana ndi gulu lathu laukadaulo.
Kuti mudziwe zambiri zokhudza ma antenna, chonde pitani ku:
