Litsamaisong tsa puisano tsa microwave le RF, ho fihlella lets'oao le matla la antenna ho bohlokoa bakeng sa ts'ebetso e tšepahalang. Hore na u moqapi oa sistimi, moetsi oa **RF Antenna**, kapa mosebelisi oa ho qetela, ho utloisisa lintlha tse ntlafatsang matla a lets'oao ho ka thusa ho ntlafatsa lihokelo tse se nang mohala. Sengoloa sena se hlahloba lintlha tsa bohlokoa tse ntlafatsang matla a lets'oao la antenna, ka temohisiso e tsoang ho **Bahlahisi ba Antenna ba microwave** le mehlala e kenyeletsang **Li-Antenna tsa Biconical** le **Antenna tsa Manaka a 24 GHz**.
1. Phaello le Tataiso ea Antena
Antenna e nang le phaello e phahameng, joalo ka Antenna ea Lenaka la **24 GHz**, e tsepamisa matla a RF ka lehlakoreng le itseng, e eketsa matla a lets'oao ka mokhoa o ikhethang haholo ka har'a lebone leo. Li-antenna tse tataisang (mohlala, lijana tsa parabolic, li-antenna tsa lenaka) li sebetsa hantle ho feta mefuta ea omnidirectional (mohlala, **Biconical Antennas**) lihokelong tsa ntlha-ho-ntlha empa li hloka ho lokisoa ka nepo.Bahlahisi ba Antenna ea Microwave** ntlafatsa phaello ka ho ntlafatsa moralo joalo ka liphetoho tsa sekhutlo sa ho phatloha ha li-antenna tsa manaka kapa sebopeho sa reflector li-antenna tsa dish.
2. Ho Fokotsa Tahlehelo
Ho senyeha ha letshwao ho etsahala ka lebaka la:
- **Litahlehelo tsa Feedline**: Likhoele tsa coaxial tsa boleng bo tlaase kapa li-adapter tsa waveguide li kenya ho fokotseha ha motlakase. Likhoele tse nang le tahlehelo e tlase le ho bapisa impedance hantle hoa hlokahala.
- **Tahlehelo ea Thepa**: Li-conductor tsa li-antenna (mohlala, koporo, aluminium) le li-substrate tsa dielectric li tlameha ho fokotsa tahlehelo ea resistive le dielectric.
- **Tšitiso ea Tikoloho**: Mongobo, lerōle, kapa lintho tse haufi tsa tšepe li ka hasanya matšoao. Meralo e thata e tsoang ho **RF Antenna Manufacturers** e fokotsa litlamorao tsena.
3. Ntlafatso ea Maqhubu le Bandwidth
Maqhubu a phahameng (mohlala,24 GHz) e dumella mahlasedi a masesaane le keketseho e phahameng empa a kotsing e kgolo ya ho monyela sepakapakeng. **Di-Antenna tsa Biconical**, ka bandwidth ya tsona e pharaletseng, di fapanyetsana keketseho bakeng sa ho tekwa le ditshebediso tsa maqhubu a mangata. Ho kgetha leqhubu le nepahetseng la maqhubu bakeng sa nyeoe ya tshebediso ho bohlokwa.
RM-DPHA2442-10 (24-42GHz)
RM-BCA2428-4 (24-28GHz)
Lihlahisoa tsa Antenna tsa RFMiso 24GHz
4. Teko e Nepahetseng le Tekanyo
**Teko ea Antenna ea RF** e netefatsa hore ts'ebetso e fihlela litlhoko tse hlalositsoeng. Mekhoa e kang:
- **Litekanyo tsa Kamore ea Anechoic** ho netefatsa mekhoa ea mahlaseli.
- **Tlhahlobo ea Network Analyzer** bakeng sa tahlehelo ea ho khutla le VSWR.
- **Teko ea Mafatše a Hole** ho netefatsa keketseho le bophara ba beam.
Bahlahisi ba itshetlehile ka mekgwa ena ho lokisa di-antenna pele di sebediswa.
5. Ho Beha Antena le Litlhophiso tsa Array
- **Bophahamo le Sebaka**: Ho phahamisa li-antenna ho fokotsa ho bonahatsa ha mobu le ho sitisa.
- **Mefuta ya Antena**: Ho kopanya dielemente tse ngata (mohlala, mefuta e arotsoeng ka mekhahlelo) ho ntlafatsa matla a lets'oao ka tshitiso e hahang.
Qetello
Letšoao le matla la antenna le hlaha ka lebaka la moralo o hlokolosi (thepa e nang le phaello e phahameng, tahlehelo e tlase), khetho e nepahetseng ea maqhubu, **Teko ea Antenna ea RF**, le ho kenngoa hantle. **Bahlahisi ba Antenna ea microwave** ba sebelisa melao-motheo ena ho fana ka litharollo tse matla joalo ka **Antenna ea Horn ea 24 GHz** bakeng sa lits'ebetso tsa maqhubu a millimeter kapa **Antenna ea Biconical** bakeng sa liteko tsa EMC. Ebang ke bakeng sa radar, 5G, kapa puisano ea sathelaete, ho beha lintlha tsena pele ho netefatsa ts'ebetso e phahameng.
