Na mpaghara ngwaọrụ radieshon elektrọn, antennas RF na antenna microwave na-enwekarị mgbagwoju anya, mana enwere ọdịiche dị mkpa n'ezie. Edemede a na-eduzi nyocha ọkachamara site na akụkụ atọ: nkọwa bandwit ugboro ugboro, ụkpụrụ imewe, na usoro nrụpụta, ọkachasị ijikọ teknụzụ isi dị ka.agụụ brazing.
RF MISOỌkụ Brazing Vacuum
1. Frequency band range na anụ ahụ e ji mara
antenna RF:
Ugboro ugboro na-arụ ọrụ bụ 300 kHz - 300 GHz, na-ekpuchi mgbasa ozi nke ọkara (535-1605 kHz) na ebili mmiri millimeter (30-300 GHz), mana ngwa ndị bụ isi na-etinye uche na <6 GHz (dị ka 4G LTE, WiFi 6). Ogologo ebili mmiri dị ogologo (ọkwa centimeter ruo mita), ihe owuwu ahụ bụ nke kachasị dipole na antenna ụtarị, yana mmetụta maka nnabata dị ala (± 1% ogologo ogologo nke anabatara).
Antenna Microwave:
Kpọmkwem 1 GHz - 300 GHz (microwave ka milimita ifegharị), ngwa ngwa ngwa ngwa ngwa dị ka X-band (8-12 GHz) na Ka-band (26.5-40 GHz). Ọkwa ebili mmiri dị mkpụmkpụ (ọkwa milimita) chọrọ:
✅ Nhazi nhazi ọkwa submillimeter (nnweta ≤± 0.01λ)
✅ Njikwa oke ikuku siri ike (<3μm Ra)
✅ Ngwakọta dielectric dị ala (ε r ≤2.2, tanδ≤0.001)
2. Mmiri mmiri nke teknụzụ mmepụta ihe
Arụmọrụ nke antenna microwave na-adabere na teknụzụ nrụpụta dị elu:
| Nkà na ụzụ | Antenna RF | Antenna Microwave |
| Teknụzụ njikọ | Ịkwado/ịghasa ihe ike | Vacuum brazed |
| Ndị na-ebubata ihe | General Electronics Factory | Ụlọ ọrụ brazing dị ka ikuku ikuku |
| chọrọ ịgbado ọkụ | Njikọ na-eduzi | Ịbanye ikuku oxygen efu, nhazigharị nhazi ọka |
| Usoro igodo | Na-eguzogide <50mΩ | Ngwakọta mgbasawanye okpomọkụ (ΔCTE <1ppm/℃) |
Isi uru nke vacuum brazing na antenna microwave:
1. Njikọ na-enweghị Oxidation: brazing na 10 -5 Torr oghere gburugburu iji zere oxidation nke Cu / Al alloys ma nọgide na-arụ ọrụ> 98% IACS
2. Thermal nchegbu mkpochapụ: gradient kpo oku n'elu liquidus nke brazing ihe (dịka BAISi-4 alloy, liquidus 575 ℃) iji kpochapụ microcracks.
3. Njikwa nrụrụ: nrụrụ n'ozuzu <0.1mm / m iji hụ na ịdịgidesi ike nke ebili mmiri millimeter
3. Ntụle ọrụ eletriki na ihe ngosi ngwa
Njirimara radieshon:
1.antenna RF: tumadi radieshon omnidirectional, nweta ≤10 dBi
2.Enten Microwave: ntụzịaka dị ukwuu (obosara obosara 1°-10°), nweta 15-50 dBi
Ngwa a na-ahụkarị:
| Antenna RF | Antenna Microwave |
| Ụlọ elu redio FM | Ngwa Array Array T/R n'usoro |
| Ihe mmetụta IoT | Nzikọrịta ozi satịlaịtị |
| RFID Tags | 5G mmWave AAU |
4. Nwalee iche nkwenye
antenna RF:
- Lekwasịrị anya: Mmekọ nke impedance (VSWR <2.0)
- Usoro: Vector network analyzer ihicha ugboro ugboro
Antenna Microwave:
- Lekwasịrị anya: ụkpụrụ radieshon/nkwekọrịta n'usoro
- Usoro: Nnyocha ubi dị nso (nkenke λ/50), nnwale ubi kọmpat
Nchikota: antennas RF bụ isi nkuku nke njikọta ikuku n'ozuzu ya, ebe antenna ngwa ndakwa nri bụ isi nke usoro ugboro ugboro na nke dị elu. Mmiri dị n'etiti ha abụọ bụ:
1. Mmụba nke ugboro ole na-eduga na mkpirisi wavelength, na-akpalite mgbanwe n'ime imewe.
2. Ntugharị usoro nrụpụta - antennas microwave na-adabere na teknụzụ ndị na-egbu egbu dị ka vacuum brazing iji hụ na arụmọrụ.
3. Ihe mgbagwoju anya ule na-eto ngwa ngwa
Ngwọta brazing Vacuum nke ụlọ ọrụ brazing ọkachamara dị ka Solar Atmosphere na-enye abụrụla ihe dị mkpa maka ntụkwasị obi nke sistemu ebili mmiri millimita. Ka 6G na-agbasawanye na eriri ugboro terahertz, uru nke usoro a ga-apụtawanye ìhè.
