Mu rwego rw'ibikoresho by'imirasire ya elegitoroniki, antene za RF na antene za mikoroonde zikunze kwitiranywa, ariko mu by'ukuri hari itandukaniro ry'ibanze. Iyi nkuru ikora isesengura ry'umwuga rishingiye ku bintu bitatu: ibisobanuro by'umuvuduko w'amajwi, amahame y'igishushanyo, n'uburyo bwo gukora, cyane cyane guhuza ikoranabuhanga ry'ingenzi nkagufunga by'umwuka.
RF MISOIfuru yo Gukoresha Imashini Ikoresha Umwotsi
1. Ingano y'umuvuduko w'amajwi n'imiterere y'umubiri
Antene ya RF:
Umurongo w'imikorere ni 300 kHz - 300 GHz, ukubiyemo uburyo bwo gusakaza amajwi hagati (535-1605 kHz) na milimetero (30-300 GHz), ariko porogaramu z'ingenzi ziba ziri kuri < 6 GHz (nka 4G LTE, WiFi 6). Uburebure bw'amajwi ni burebure (santimetero ugereranyije na metero), imiterere ahanini ni dipole na whip antene, kandi ubushobozi bwo kwihanganira amajwi ni buke (± 1% y'uburebure ni bwo bwemewe).
Antene ya mikoroonde:
By'umwihariko 1 GHz - 300 GHz (mikoroonde kugeza kuri millimetero wave), imirongo isanzwe y'ikoreshwa nka X-band (8-12 GHz) na Ka-band (26.5-40 GHz). Ibisabwa ku bunini bw'uburebure (urwego rwa millimetero):
✅ Ubuhanga bwo gutunganya urwego rwa Submillimetero (kwihanganira ≤±0.01λ)
✅ Gugenzura neza ubukana bw'ubuso (< 3μm Ra)
✅ Ingufu za dielectric zitakaza agaciro gake (ε r ≤2.2, tanδ≤0.001)
2. Iterambere ry'ikoranabuhanga mu nganda
Imikorere ya antene za mikoroonde ishingiye cyane ku ikoranabuhanga rigezweho mu gukora:
| Ikoranabuhanga | Antena ya RF | Antena ya mikoroonde |
| Ikoranabuhanga ryo guhuza | Gupfunyika/Gufunga screw | Ifite icyuma gifunga umwuka |
| Abatanga serivisi basanzwe | Uruganda Rukuru rw'Ibintu Bikoresha Ikoranabuhanga | Ibigo bitanga ubushyuhe nk'ikirere cy'izuba |
| Ibisabwa mu gusudira | Guhuza umurongo w'amashanyarazi | Nta mwuka winjiramo, nta ngaruka zigaragara mu miterere y'ibinyampeke |
| Ibipimo by'ingenzi | Irinda gukoreshwa <50mΩ | Guhuza igipimo cyo kwagura ubushyuhe (ΔCTE<1ppm/℃) |
Agaciro k'ingenzi k'icyuma gifunga umwuka muri antene za mikoroonde:
1. Guhuza nta ogisijeni: gushyiramo umwuka mu kirere gishyushye cya 10 -5 Torr kugira ngo hirindwe ogisijeni ya Cu / Al alloys kandi bikomeze gutwara umuyoboro >98% by'amashanyarazi
2. Gukuraho stress y'ubushyuhe: gushyushya hejuru y'amazi y'ibikoresho byo gushyushya (urugero: BAISi-4 alloy, liquidus 575℃) kugira ngo hakurweho imiyoboro mito
3. Kugenzura impinduka: impinduka rusange <0.1mm/m kugira ngo habeho imiterere ihamye y'urumuri rwa milimetero
3. Kugereranya imikorere y'amashanyarazi n'ikoreshwa ryayo
Ibiranga imirasire:
1.Antene ya RF: imirasire ikoresha icyerekezo kimwe, kwiyongera ≤10 dBi
2.Antene ya mikoroonde: icyerekezo cyo hejuru (ubugari bw'umuraba 1°-10°), yunguka 15-50 dBi
Porogaramu zisanzwe:
| Antena ya RF | Antena ya mikoroonde |
| Umunara wa radiyo ya FM | Ibice bya Radar ya Phased Array T/R |
| Ibipimo bya IoT | Urubuga rw'itumanaho rya satelite |
| Ibirango bya RFID | 5G mmWave AAU |
4. Itandukaniro ryo kugenzura ikizamini
Antene ya RF:
- Icyibandwaho: Guhuza impedance (VSWR < 2.0)
- Uburyo: Gushakisha inshuro nyinshi uburyo Vector analyzer network frequency sweep
Antene ya mikoroonde:
- Icyibandwaho: Imiterere y'imirasire/uburyo ihagaze
- Uburyo: Gusuzuma hafi y'umurima (ubunyangamugayo bwa λ/50), ikizamini gito cy'umurima
Umwanzuro: Antene za RF ni inkingi y'ifatizo mu guhuza insinga, mu gihe antene za microwave ari inkingi y'uburyo bwo gukoresha frequency nyinshi n'ubuhanga buhanitse. Amazi ari hagati y'ibi byombi ni:
1. Ukwiyongera k'umuvuduko w'urumuri bituma uburebure bw'urumuri bugabanuka, bigatera impinduka mu miterere y'igishushanyo
2. Impinduka mu mikorere - antene za mikoroonde zikoresha ikoranabuhanga rigezweho nko gukoresha icyuma gifunga umwuka kugira ngo zikore neza
3. Ubuhanga mu igerageza burushaho kwiyongera
Ibisubizo byo gufunga by’ibikoresho biva mu cyuma bitangwa n’ibigo by’inzobere mu gufunga nk’ikirere cy’izuba byabaye garanti y’ingenzi ku buryo sisitemu z’imiraba ya milimetero zizewe. Uko 6G igenda ikura ikagera ku murongo wa terahertz, agaciro k’iyi gahunda kazarushaho kugaragara.
Kugira ngo umenye byinshi kuri antene, sura:
