Mune microwave kutaurirana masisitimu, antenna kuwana chiratidzo chakakosha chekuyera kuita kwemwaranzi. Senyanzvimicrowave antenna mutengesi, isu tinonyatsoziva kukosha kwekunyatso kuverenga uye kuyera antenna kuwana kwekugadzirisa system. Ichi chinyorwa chichatora40GHz antennauyeCassegrain antennasemienzaniso yekusuma zvakadzama nzira yekuverenga uye mapoinzi anoshanda ekuwana antenna.
1. Theoretical kukarukureta hwaro
Antenna kuwana (dBi) inotemerwa nekutungamira uye kushanda nesimba:
Gain (dBi) = kutungamira × kugona
1. Directivity calculation:
Inowanwa nekubatanidza iyo mwaranzi pateni, yakakwirira-directivity antennas (yakadai seCassegrain antennas) inogona kuisa simba mudanda rakatetepa.
2. Mafungiro ekubudirira:
Zvinotevera kurasikirwa zvinhu zvinofanirwa kutariswa:
- Feeder kurasikirwa (senge waveguide kuremerwa kusawirirana)
- Kurasikirwa kwezvinhu
- Surface kugadzirisa iko kurongeka
2. Nyanzvi dzekuyera nzira
1. Kuenzanisa bvunzo nzira:
Enzanisa antenna iri pasi pekuedzwa (senge 40GHz antenna) neyakajairwa kuwana nyanga antenna.
2. Kure-munda bvunzo:
Pima iyo radiation patani mu microwave rima mukamuri, iri inyanzvi yekuyedza nzira inowanzoshandiswa ne ** antenna vatengesi **.
3. Network analyzer bvunzo:
Ongorora kurasikirwa kwekudzoka uye kugona kwemwaranzi kuburikidza neS parameter yekuongorora.
Broadband Horn Antenna(18-40GHz)
Waveguide kune Coaxial Adapter (26.5-40GHz)
Waveguide Probe Antenna(26.5-40GHz)
RFmiso40Ghz Antenna Zvigadzirwa
3.Simulation verification teknolojia
Shandisa nyanzvi yemagetsi simulation software yakadai seHFSS neCST:
-Kunyatso verenga kugona kweaperture (kunyanya kukosha ku **Cassegrain antenna ** uye mamwe antenna anoratidza)
- Ongorora kurongeka kwekudya
- Ongorora kukanganisa kwe **waveguidemutoro**
4. Pfungwa huru dzekuita engineering
1. Frequency maitiro:
Kuwana kweAntenna kune yakakosha frequency correlation (senge kuwana kwe40GHz antenna kuchadzikira pa30GHz).
2. Zvinhu zvakatipoteredza:
Nzvimbo yekuisa, kupindira kwakatenderedza, nezvimwe zvinokanganisa kuita kwekuwana chaiko.
3. Maitiro ekuda:
Precision machining inovimbisa kuti theoretical dhizaini inogona kuitika.
Cassegrain Antenna (26.5-40GHz)
Zano reunyanzvi:
Nezvakakosha zvinodiwa senge ** 40GHz antenna ** mune millimeter wave bhendi kana ** Cassegrain antenna ** ine kupfuma kwakanyanya, zvinokurudzirwa kushandira pamwe nenyanzvi ** microwave antenna mutengesi ** ine yakakwana yekuyedza kugona kuti uone kushanda kwechigadzirwa.
Tine:
- Complete test room
- Nyanzvi yekuyera timu
- Yakapfuma engineering ruzivo
Kuti uwane mamwe antenna kuwana optimization mhinduro, ndapota inzwa wakasununguka kubata timu yedu yehunyanzvi.
Kuti udzidze zvakawanda nezve antennas, ndapota shanya:
Nguva yekutumira: Kubvumbi-10-2025
