M'makina olankhulirana a microwave, kupindula kwa mlongoti ndi chizindikiro chofunikira pakuyesa magwiridwe antchito a radiation. Monga katswirimicrowave antenna ogulitsa, tikudziwa bwino za kufunika kowerengera molondola ndi kuyeza kupindula kwa mlongoti kuti muwongolere makina. Nkhaniyi itenga40 GHz antennandiCassegrain antennamonga zitsanzo zofotokozera mwatsatanetsatane njira yowerengera ndi mfundo zothandiza za phindu la mlongoti.
1. Theoretical mawerengedwe maziko
Kupindula kwa mlongoti (dBi) kumatsimikiziridwa ndi chiwongolero ndi mphamvu:
Kupindula (dBi) = kuwongolera × kuchita bwino
1. Kuwerengera Directivity:
Zopezedwa pophatikiza mawonekedwe a radiation, tinyanga tating'onoting'ono (monga Cassegrain antennas) zimatha kuyika mphamvu mumtengo wopapatiza.
2. Malingaliro ochita bwino:
Zinthu zotsatirazi zotayika ziyenera kuganiziridwa:
- Kutayika kwa feeder (monga kusagwirizana kwa ma waveguide)
- Kutayika kwa zinthu
- Kulondola kwapamwamba pakukonzekera
2. Njira zoyezera akatswiri
1. Njira yofananira yoyesera:
Fananizani mlongoti woyesedwa (monga mlongoti wa 40GHz) ndi mlongoti wokhazikika wa nyanga.
2. Mayeso akutali:
Yezerani mawonekedwe a radiation muchipinda chamdima cha microwave, chomwe ndi njira yoyesera yaukadaulo yomwe imagwiritsidwa ntchito ndi **opereka tinyanga**.
3. Mayeso a network analyzer:
Unikani kutayika kobwerera komanso mphamvu zama radiation kudzera pakuwunika kwa parameter ya S.
Broadband Horn Antenna(18-40GHz)
Waveguide to Coaxial Adapter (26.5-40GHz)
Waveguide Probe Antenna(26.5-40GHz)
RFmiso40Ghz Zopangira Antenna
3.Simulation kutsimikizira luso
Gwiritsani ntchito pulogalamu yaukadaulo yamagetsi yamagetsi monga HFSS ndi CST:
- Kuwerengera molondola kabowo (makamaka kofunikira kwa **Cassegrain antenna** ndi tinyanga zina zowunikira)
- Unikani momwe chakudya chimayendera
- Onani zotsatira za **waveguidekatundu **
4. Mfundo zazikuluzikulu za machitidwe a uinjiniya
1. Mawonekedwe a pafupipafupi:
Kupindula kwa mlongoti kumakhala ndi kulumikizana kwafupipafupi (monga kupindula kwa mlongoti wa 40GHz kudzatsika pa 30GHz).
2. Zinthu zachilengedwe:
Malo oyika, kusokoneza kozungulira, ndi zina zotero zidzakhudza kupindula kwenikweni.
3. Zofunikira pakukonza:
Makina olondola amatsimikizira kuti mapangidwe amalingaliro amatha kuchitika.
Antenna ya Cassegrain (26.5-40GHz)
Malangizo akatswiri:
Pazofunikira zapadera monga ** 40GHz antenna ** mu bandi ya millimeter wave kapena ** Cassegrain antenna ** ndi kupindula kwakukulu, tikulimbikitsidwa kuti tigwirizane ndi katswiri ** microwave antenna supplier ** ndi kuthekera kokwanira kuyesa kuonetsetsa kuti malonda akugwira ntchito.
Tili ndi:
- Chipinda choyesera chathunthu
- Gulu loyezera akatswiri
- Chidziwitso cholemera chaukadaulo
Kuti mumve zambiri zamayankho kukhathamiritsa kwa antenna, chonde omasuka kulumikizana ndi gulu lathu laukadaulo.
Kuti mudziwe zambiri za antennas, chonde pitani:
