Antenna ya Microwave ihindura ibimenyetso byamashanyarazi mumashanyarazi ya electromagnetique (naho ubundi) ukoresheje ibikoresho byakozwe neza. Imikorere yabo ishingiye ku mahame atatu y'ingenzi:
1. Guhindura amashanyarazi ya elegitoroniki
Kohereza uburyo:
Ibimenyetso bya RF biva mubitambuka binyuze muburyo bwa antenna ihuza (urugero, SMA, N-ubwoko) kugeza aho bagaburira. Ibikoresho bya antene (amahembe / dipole) bihindura imiraba mumirongo yerekeza.
Akira Uburyo:
Impanuka ya EM itera imbaraga muri antenne, igasubira mubimenyetso byamashanyarazi kubakira
2. Ubuyobozi & Kugenzura Imirasire
Ubuyobozi bwa Antenna bugereranya kwibanda kumurongo. Antenna ihanitse cyane (urugero, ihembe) yibanda cyane mumyanya mito, iyobowe na:
Ubuyobozi (dBi) log 10 log₁₀ (4πA / λ²)
Aho A = aperture agace, λ = uburebure bwumurongo.
Ibicuruzwa bya antenna ya Microwave nkibiryo bya parabolike bigera> 30 dBi yubuyobozi bwa satelite.
3. Ibyingenzi byingenzi ninshingano zabo
| Ibigize | Imikorere | Urugero |
|---|---|---|
| Imirasire | Guhindura ingufu z'amashanyarazi-EM | Patch, dipole, ahantu |
| Umuyoboro | Kuyobora imiraba hamwe nigihombo gito | Waveguide, umurongo wa microstrip |
| Ibigize Passive | Kongera ibimenyetso byerekana ubunyangamugayo | Icyiciro cyimura, polarizeri |
| Abahuza | Imigaragarire hamwe n'imirongo yohereza | 2.92mm (40GHz), 7/16 (Pwr yo hejuru) |
4. Igishushanyo cyihariye-Igishushanyo
<6 GHz: Antenna ya Microstrip yiganje kubunini buke.
> 18 GHz: Amahembe ya Waveguide arenze kubikorwa byo gutakaza bike.
Ikintu gikomeye: Impedance ihuye na antenna ihuza ibuza gutekereza (VSWR <1.5).
Porogaramu nyayo-Isi:
5G Massive MIMO: Microstrip igizwe nibice bya passiyo yo kuyobora ibiti.
Sisitemu ya Radar: Ubuyobozi bukomeye bwa antene butuma intego ikurikirana neza.
Satellite Comms: Imashanyarazi ya parabolike igera kuri 99% aperture.
Umwanzuro: Antenne ya Microwave yishingikiriza kuri electroniki ya magnetiki resonance, ubwoko bwa antenna ihuza neza, hamwe na antenne yuburyo bwiza bwo kohereza / kwakira ibimenyetso. Ibicuruzwa bigezweho bya microwave antenna ihuza ibice bya pasiporo kugirango igabanye igihombo kandi igabanye intera.
Kugira ngo umenye byinshi kuri antene, nyamuneka sura:
