Ma antenna a microwave, kuphatikizapo ma antenna a X-band horn ndi ma antenna a high-gain waveguide probe, ndi otetezeka kwambiri akapangidwa ndikugwiritsidwa ntchito moyenera. Chitetezo chawo chimadalira zinthu zitatu zofunika: kuchuluka kwa mphamvu, kuchuluka kwa ma frequency, ndi nthawi yomwe amawonekera.
1. Miyezo Yotetezera Kudzera mu Radiation
Malire Olamulira:
Ma antenna a microwave amatsatira malire a FCC/ICNIRP (monga, ≤10 W/m² m'malo opezeka anthu ambiri a X-band). Makina a radar a PESA amaphatikiza kutseka kwa magetsi kokha anthu akamayandikira.
Zotsatira za pafupipafupi:
Ma frequency apamwamba (monga X-band 8–12 GHz) ali ndi kuya kosaya kwambiri kolowera (<1mm pakhungu), zomwe zimachepetsa chiopsezo cha kuwonongeka kwa minofu poyerekeza ndi ma RF otsika.
2. Zinthu Zotetezera Pakapangidwe
Kukonza Bwino kwa Antena:
Mapangidwe ogwira ntchito bwino kwambiri (>90%) amachepetsa kuwala kochokera ku dzuwa. Mwachitsanzo, ma antenna a probe a waveguide amachepetsa ma sidelobes kufika <–20 dB.
Zotchingira ndi Zotsekereza:
Machitidwe ankhondo/zachipatala amaika zikwama za Faraday ndi masensa oyenda kuti apewe kuwonekera mwangozi.
3. Mapulogalamu a Padziko Lonse
| Chitsanzo | Muyeso wa Chitetezo | Mulingo Woopsa |
|---|---|---|
| Malo Oyambira a 5G | Kupanga beamforming kumapewa kukhudzidwa ndi anthu | Zochepa |
| Rada ya Bwalo la Ndege | Malo oletsedwa ndi mipanda | Zosafunika |
| Kujambula Zachipatala | Kugwira ntchito mozungulira (<1% ya ntchito) | Wolamulidwa |
Pomaliza: Ma antenna a microwave ndi otetezeka akamatsatira malamulo ndi kapangidwe koyenera. Kuti ma antenna azitha kugwira ntchito bwino, sungani mtunda wa >5m kuchokera pamalo otseguka. Nthawi zonse onetsetsani kuti ma antenna akugwira ntchito bwino komanso kuti chitetezo chake chili bwino musanagwiritse ntchito.
Kuti mudziwe zambiri zokhudza ma antenna, chonde pitani ku:
