Lefapheng la disebediswa tsa mahlasedi a motlakase, di-antenna tsa RF le di-antenna tsa microwave hangata di a ferekana, empa ha e le hantle ho na le dipharologanyo tsa motheo. Sengolwa sena se etsa tlhahlobo ya botsebi ho tloha dikarolong tse tharo: tlhaloso ya leqhubu la maqhubu, molao-motheo wa moralo, le tshebetso ya tlhahiso, haholoholo ho kopanya mahlale a bohlokwa a kangho betla ka vacuum.
RF MISOSebōpi sa ho Sireletsa ka Letsoho
1. Mefuta ea lebanta la maqhubu le litšobotsi tsa 'mele
Antena ea RF:
Leqhubu la maqhubu a tshebetso ke 300 kHz - 300 GHz, le akaretsa kgaso ya maqhubu a mahareng (535-1605 kHz) ho isa ho millimeter wave (30-300 GHz), empa ditshebediso tsa mantlha di tsepamisitse maikutlo ho < 6 GHz (jwalo ka 4G LTE, WiFi 6). Bolelele ba maqhubu bo bolelele (disentimitara ho ya boemong ba mithara), sebopeho haholo-holo ke dipole le whip antenna, mme kutlwisiso ya mamello e tlase (±1% ya bolelele ba maqhubu e a amoheleha).
Antena ea microwave:
Haholo-holo 1 GHz - 300 GHz (maqhubu a microwave ho isa ho millimeter), mefuta e tloaelehileng ea maqhubu a ts'ebeliso joalo ka X-band (8-12 GHz) le Ka-band (26.5-40 GHz). Litlhoko tsa bolelele bo bokhutšoanyane ba maqhubu (boemo ba millimeter):
✅ Ho nepahala ha ts'ebetso ea boemo ba submillimeter (mamello ≤±0.01λ)
✅ Taolo e thata ea ho rarahana ha bokaholimo (< 3μm Ra)
✅ Substrate ea dielectric e nang le tahlehelo e tlase (ε r ≤2.2, tanδ≤0.001)
2. Mehloli ea theknoloji ea tlhahiso
Tshebetso ya di-antenna tsa microwave e itshetlehile haholo theknolojing ya tlhahiso ya maemo a hodimo:
| Theknoloji | Antenna ea RF | Antenna ea microwave |
| Theknoloji ea khokahano | Ho kopanya/ho tiisa screw | E entsoe ka lephaka |
| Bafepedi ba Tloaelehileng | Feme ea Lisebelisoa tsa Elektroniki tse Akaretsang | Likhamphani tsa ho besa tse kang Solar Atmospheres |
| Litlhoko tsa ho tjheseletsa | Khokahano ea motlakase | Ho se kenelle oksijene hantle, ho hlophisoa bocha ha sebopeho sa lijo-thollo |
| Litekanyo tsa Bohlokoa | Ho hanyetsa <50mΩ | Ho bapisa coefficient ea katoloso ea mocheso (ΔCTE<1ppm/℃) |
Boleng ba mantlha ba ho betla ka vacuum ka har'a li-antenna tsa microwave:
1. Kgokelo e se nang oksideshene: ho besa ka hara tikoloho ya vacuum ya 10 -5 Torr ho qoba oksideshene ya dialloy tsa Cu/Al le ho boloka conductivity >98% IACS
2. Ho tlosa khatello ea mocheso: ho futhumatsa ha gradient ho ea holimo ho mokelikeli oa thepa ea brazing (mohlala, motsoako oa BAISi-4, mokelikeli oa 575℃) ho felisa mapetso a manyenyane.
3. Taolo ea phetoho: phetoho ka kakaretso <0.1mm/m ho netefatsa botsitso ba mohato oa maqhubu a millimeter
3. Papiso ea ts'ebetso ea motlakase le maemo a ts'ebeliso
Litšobotsi tsa mahlaseli:
1.Antenna ea RF: mahlaseli a fapaneng haholo-holo, a eketsehang ≤10 dBi
2.Antenna ea microwave: e shebang ka tsela e phahameng (bophara ba mahlasedi ke 1°-10°), eketsa 15-50 dBi
Likopo tse tloaelehileng:
| Antenna ea RF | Antenna ea microwave |
| Tora ea seea-le-moea ea FM | Likarolo tsa T/R tsa Radar e Phased Array |
| Li-sensor tsa IoT | Fepa ea puisano ea sathelaete |
| Li-tag tsa RFID | 5G mmWave AAU |
4. Liphapang tsa netefatso ea liteko
Antena ea RF:
- Tsepamiso: Ho bapisa Impedance (VSWR < 2.0)
- Mokhoa: Sesebelisoa sa ho hlahloba maqhubu a marang-rang a vector
Antena ea microwave:
- Tsepamiso: Paterone ea mahlaseli/ho tsitsa ha mohato
- Mokhoa: Ho skena ha haufi le tšimo (ho nepahala ha λ/50), teko e nyane ea tšimo
Qeto: Li-antenna tsa RF ke lejoe la motheo la khokahano e akaretsang ea waelese, ha li-antenna tsa microwave e le motheo oa litsamaiso tse nang le maqhubu a phahameng le tse nepahetseng haholo. Karolo e pakeng tsa tse peli ke:
1. Keketseho ea maqhubu e lebisa ho khutsufalo ea bolelele ba leqhubu, e leng se bakang phetoho ea paradigm moralong
2. Phetoho ea ts'ebetso ea tlhahiso - li-antenna tsa microwave li itšetlehile ka mahlale a morao-rao a kang vacuum brazing ho netefatsa ts'ebetso
3. Ho rarahana ha teko ho hola ka potlako
Litharollo tsa ho betla ka vacuum tse fanoang ke lik'hamphani tsa litsebi tsa ho betla tse kang Solar Atmospheres e se e le tiisetso ea bohlokoa bakeng sa ho tšepahala ha litsamaiso tsa maqhubu a millimeter. Ha 6G e ntse e atoloha ho ea ho sehlopha sa maqhubu a terahertz, boleng ba ts'ebetso ena bo tla hlahella haholoanyane.
Ho ithuta haholoanyane ka li-antenna, ka kopo etela:
