Microwave antennas, kusanganisira X-band horn antennas uye high-gain waveguide probe antennas, zvakachengetedzeka zvakachengeteka kana zvakagadzirwa uye zvichishandiswa nemazvo. Kuchengetedzeka kwavo kunoenderana nezvinhu zvitatu zvakakosha: simba density, frequency renji, uye kuratidzwa nguva.
1. Radiation Safety Standards
Regulatory Limits:
Microwave antennas anoenderana neFCC/ICNIRP exposure limits (semuenzaniso, ≤10 W/m² yeX-band nzvimbo dzeveruzhinji). PESA radar masisitimu anosanganisira otomatiki kucheka magetsi kana vanhu vasvika.
Frequency Impact:
Mafambiro epamusoro (semuenzaniso, X-bhendi 8–12 GHz) ane kudzika kwakadzika kwekupinda (<1mm muganda), kuderedza ngozi yekukuvadzwa kwetishu maringe nekudzika-frequency RF.
2. Dhizaini Yekuchengetedza Zvimiro
Antenna Efficiency Optimization:
Dhizaini yepamusoro-soro (> 90%) inoderedza mwaranzi inorasika. Semuenzaniso, waveguide probe antennas inoderedza sidelobes kusvika <-20 dB.
Shielding & Interlocks:
Military/medical systems embed Faraday makeji uye mafambiro sensors kudzivirira kuratidzwa netsaona.
3. Real-World Applications
| Scenario | Chiyero Chekuchengetedza | Risk Level |
|---|---|---|
| 5G Base Zviteshi | Beamforming inodzivirira kuratidzwa kwevanhu | Low |
| Airport Radar | Nzvimbo dzakakomberedzwa dzekusabatanidzwa | Negligible |
| Medical Imaging | Pulsed operation (<1% duty cycle) | Controlled |
Mhedziso: Microwave antennas yakachengeteka kana ichiomerera kumiganhu yemitemo uye dhizaini chaiyo. Kune antenna akakwira, chengetedza> 5m chinhambwe kubva kune anoshanda apertures. Gara uchisimbisa kushanda kweantenna uye kudzivirira usati watumirwa.
Kuti udzidze zvakawanda nezve antennas, ndapota shanya:
