Pfupiso:
Sechinhu chakakosha muinjiniya ye microwave, ma antenna ehorn akabudirira kushandiswa zvisina muganho mukushandiswa kwakasiyana-siyana nekuda kwehunhu hwawo hwemagetsi uye kuvimbika kwechimiro. Iyi technical brief inoongorora hukuru hwawo mu RF systems dzemazuva ano.
Zvakanakira zvehunyanzvi:
Kushanda kweBroadband: Inoratidza hunhu hwemwaranzi hunogara huripo pabandwidths dze multi-octave (kazhinji 2:1 kana kupfuura), antennas dzenyanga dzinoshanda sezvinodiwa muKanyanga ye11dBimaitiro ekugadzirisa huwandu hwenzvimbo.
Antena yeNyanga yeBroadband (0.5-6GHz, 11dBi)
Antena yeBroadband Dual Polarized Horn (0.8-12GHz，11dBi)
Antena yeNyanga yeBroadband (0.6-6GHz, 11dBi)
RF MisoZvigadzirwa zve11dbi zvakatevedzana
Hunhu hweMwaranzi Yakarurama:
Kugadzikana kwehupamhi hwemabheya ≤ ±2° pabandwidth yekushanda
Kusiyanisa kwepolarization yemuchinjikwa > 25dB
VSWR < 1.25:1 kuburikidza neyakagadziriswakuputira vacuumkugadzira
Kuvimbika kweMaumbirwo:
Ma alloy e aruminiyamu emhando yemauto ane < 5μm roughness pamusoro
Kuvharwa kwemhepo kunochengetedza nharaunda yakaoma (-55°C kusvika +125°C)
Kuongorora Mashandisirwo:
Masisitimu eRadar:
Radha yePESA: Inoshanda sechinhu chekudyisa ma "passive arrays"
Radar yeAESA: Inoshandiswa mukuenzanisa pasi pearray uye kuyedza pedyo nemunda
Masisitimu ekuyera:
Chiyero chekuwana mari yekutanga muKuedzwa kweantenna yeRFmidziyo
Kusimbiswa kwenzvimbo dziri kure
Kuongororwa kweEMI/EMC paMIL-STD-461G
Masisitimu Ekutaurirana:
Nzvimbo dzepasi pesatellite dzinopa ma "feeds"
Zvinongedzo zve microwave zvinonongedza poindi imwe neimwe
Kuongororwa kwechiteshi chepasi che5G mmWave
Kuongorora Kuenzanisa:
Kunyange zvazvo dzimwe antenna dziripo, magadzirirwo ehorn anoramba ari pamusoro nekuda kwe:
Mutengo wepamusoro/chiyero chekushanda zvakanaka
Kutevedza kwakasimbiswa kwekuongorora
Kuvimbika kwakaratidzwa (>100,000 hr MTBF)
Mhedziso:
Musanganiswa we antenna yenyanga wekufanotaura kugona kwayo kushandisa electromagnetic, kusimba kwemuchina, uye kugona kwayo kuyera zvakare kunoita kuti irambe ichishandiswa mu microwave engineering. Kufambira mberi kuri kuitwa mu vacuum brazing uye machinery chaiyo kunowedzera kushanda kwayo kune masystem echizvarwa chinotevera.
