N'ihe gbasara ngwaọrụ radieshọn elektrọnik, antenna RF na antenna microwave na-agbagwoju anya, mana enwere ọdịiche dị mkpa n'ezie. Isiokwu a na-eme nyocha ọkachamara site na akụkụ atọ: nkọwa nke eriri ugboro ugboro, ụkpụrụ imewe, na usoro mmepụta, ọkachasị ijikọta teknụzụ ndị bụ isi dịkabrazing vacuum.
RF MISOIgwe ọkụ na-enwu ọkụ
1. Oke ụda ugboro na njirimara anụ ahụ
Antenna RF:
Oke ugboro ọrụ ahụ bụ 300 kHz - 300 GHz, nke na-ekpuchi mgbasa ozi ebili mmiri dị n'etiti (535-1605 kHz) ruo milimita (30-300 GHz), mana ngwa ndị bụ isi na-agbakọ na <6 GHz (dịka 4G LTE, WiFi 6). Ogologo ebili mmiri ahụ dị ogologo (sentimita ruo mita), nhazi ahụ bụ antenna dipole na whip, mmetụta nke ndidi dịkwa ala (±1% a na-anabata ebili mmiri).
Antenna ngwa ndakwa nri:
Kpọmkwem 1 GHz - 300 GHz (ngwa ndakwa nri ruo milimita), eriri ugboro ole eji eme ihe dịka X-band (8-12 GHz) na Ka-band (26.5-40 GHz). Ihe achọrọ maka obere ogologo ebili mmiri (ọkwa milimita):
✅ Izi ezi nhazi ọkwa Submillimeter (nchekwa ≤±0.01λ)
✅ Njikwa oke ike n'elu (< 3μm Ra)
✅ Ihe na-eme ka ihe dị n'ime ala dị obere (ε r ≤2.2, tanδ≤0.001)
2. Ọdịiche dị n'etiti teknụzụ mmepụta ihe
Arụmọrụ nke antenna microwave dabere na teknụzụ mmepụta dị elu:
| Teknụzụ | RF mpi | Ngwa ndakwa nri |
| Teknụzụ njikọ | Njikọta ihe nkwado/skru | A na-asacha Vacuum |
| Ndị Na-ebunye Ihe Nkịtị | Ụlọ ọrụ Eletrọniki Izugbe | Ụlọ ọrụ na-eme brazing dịka ikuku anyanwụ |
| Ihe achọrọ maka ịgbado ọkụ | njikọ na-eduzi | Enweghị ike ịbanye oxygen, nhazi nhazi ọka |
| Isi Metrics | Nguzogide na-adịghị ike <50mΩ | Ndakọrịta nke oke mgbasawanye okpomọkụ (ΔCTE <1ppm/℃) |
Uru dị mkpa nke brazing vacuum na antenna microwave:
1. Njikọ na-enweghị oxidation: brazing na gburugburu vacuum 10-5 Torr iji zere oxidation nke alloys Cu/Al ma nọgide na-enwe conductivity >98% IACS
2. Mwepụ nrụgide okpomọkụ: ikpo ọkụ gradient ruo n'elu mmiri mmiri nke ihe brazing (dịka ọmụmaatụ BAISi-4 alloy, mmiri mmiri 575℃) iji wepụ obere mgbawa
3. Njikwa mgbanwe: mgbanwe zuru oke <0.1mm/m iji hụ na usoro ebili mmiri milimita na-agbanwe agbanwe
3. Ntụnyere arụmọrụ eletriki na ọnọdụ ngwa
Njirimara radieshọn:
1.Antenna RF: ọkachasị radieshon omnidirectional, uru ≤10 dBi
2.Antenna ngwa ndakwa nri: nke nwere ike ịga n'ihu nke ọma (obosara ogwe osisi 1°-10°), nweta 15-50 dBi
Ngwa ndị a na-ahụkarị:
| RF mpi | Ngwa ndakwa nri |
| Ụlọ elu redio FM | Ihe ndị mejupụtara Radar T/R nke usoro nhazi |
| Ihe mmetụta IoT | Ntanetị nkwukọrịta satịlaịtị |
| Mkpado RFID | 5G mmWave AAU |
4. Ihe dị iche n'ihe gbasara nkwenye ule
Antenna RF:
- Nlekwasị anya: Ndakọrịta mgbochi (VSWR < 2.0)
- Usoro: Nyocha ugboro ole nke Vektọ netwọk
Antenna ngwa ndakwa nri:
- Nlekwasị anya: Usoro/usoro nhazi nke radieshọn
- Usoro: N'akụkụ nyocha ubi (izizi λ/50), nnwale ubi dị obere
Mmechi: Antenna RF bụ isi ihe dị mkpa maka njikọ ikuku zuru oke, ebe antenna microwave bụ isi ihe dị mkpa maka sistemụ ugboro ugboro na nke ziri ezi. Isi ihe dị n'etiti ha abụọ bụ:
1. Mmụba ugboro ugboro na-eduga na ogologo ebili mmiri dị mkpụmkpụ, na-akpali mgbanwe atụmatụ na imewe
2. Mgbanwe usoro mmepụta - antenna microwave na-adabere na teknụzụ kachasị ọhụrụ dịka brazing vacuum iji hụ na arụmọrụ ya dị mma.
3. Ihe mgbagwoju anya nke ule na-eto nke ukwuu
Ngwọta brazing vacuum nke ụlọ ọrụ brazing ọkachamara dịka Solar Atmospheres na-enye abụrụla ihe dị mkpa maka ntụkwasị obi nke sistemụ ebili mmiri millimeter. Ka 6G na-agbasa ruo na band frequency terahertz, uru nke usoro a ga-apụta ìhè karịa.
