Antenna Microwave na-atụgharị akara eletrik ka ọ bụrụ ebili mmiri elektrọn (na nke ọzọ) site na iji usoro arụpụtara nke ọma. Ọrụ ha dabere na isi ụkpụrụ atọ:
1. Electromagnetic Wave mgbanwe
Ụdị nnyefe:
Mgbama RF sitere na njem nnyefe site na ụdị njikọ antenna (dịka SMA, ụdị N) ruo ebe nri. Ihe ndị na-eduzi antenna (mpi/dipoles) na-akpụzi ebili mmiri ka ọ bụrụ oghe ụzọ.
Ụdị nnata:
Ebili mmiri EM na-eme eme na-eme ka ọ̀tụ̀tụ̀ mmiri dị na mpio, tụgharịa azụ na mgbama eletrik maka onye nata ya
2. Directivity & Radiation Control
Directivity Antenna na-akọwapụta nlebara anya beam. Igwe ntụzịaka dị elu (dịka ọmụmaatụ, mpi) na-etinye ike na lobes dị warara, nke:
Ntuziaka (dBi) ≈ 10 log₁₀(4πA/λ²)
Ebe A = oghere oghere, λ = ogologo ikuku.
Ngwaahịa antenna Microwave dị ka efere parabolic nwetara> 30 dBi Directivity maka njikọ satịlaịtị.
3. Isi Ihe & Ọrụ Ha
| Akụkụ | Ọrụ | Ọmụmaatụ |
|---|---|---|
| Ihe na-egbuke egbuke | Na-atụgharị ọkụ eletrik-EM ike | Patch, dipole, oghere |
| Netwọk nri | Na-eduzi ebili mmiri na obere mfu | Waveguide, microstrip ahịrị |
| Ngwa na-agafe agafe | Kwalite iguzosi ike n'ezi ihe mgbaàmà | Ndị na-agbanwe usoro, polarizers |
| Njikọ | Interface na nnyefe ahịrị | 2.92mm (40GHz), 7/16 (Pwr dị elu) |
4. Ugboro-Specific Design
<6 GHz: antennas Microstrip na-achịkwa maka nha kọmpat.
> 18 GHz: mpi Waveguide dị elu maka ịrụ ọrụ dị ala.
Ihe dị mkpa: Mkpakọrịta mgbochi na njikọ antenna na-egbochi ntụgharị uche (VSWR <1.5).
Ngwa nke ụwa n'ezie:
5G Massive MIMO: Microstrip arrays nwere ihe na-agafe agafe maka ịkwọ ụgbọ mmiri.
Sistemụ Radar: Ntụziaka dị elu nke antenna na-ahụ maka nleba anya nke ọma.
Satellite Comms: Ndị na-egosipụta parabolic na-enweta arụmọrụ oghere 99%.
Nchikota: Igwe igwe microwave na-adabere na resonance electromagnetic, ụdị njikọ antenna ziri ezi, yana ntụzịaka antenna kacha ibunye/nata akara. Ngwaahịa antenna ngwa ndakwa nri dị elu na-ejikọta ihe ndị na-agafe agafe iji belata mfu ma bulie oke.
Iji mụtakwuo maka antennas, biko gaa na:
