Isishwankathelo:
Njengenxalenye ebalulekileyo kubunjineli be-microwave, ii-antenna ze-horn ziye zasetyenziswa ngendlela engenakuthelekiswa nanto kuzo zonke iinkqubo ngenxa yeempawu zazo ezibalaseleyo ze-electromagnetic kunye nokuthembeka kwesakhiwo. Le ngcaciso yobuchwephesha ihlola ubukhulu bazo kwiinkqubo ze-RF zanamhlanje.
Iingenelo zobugcisa:
Ukusebenza kweBroadband: Ibonisa iimpawu zemitha ezihambelanayo kwiibhendi ze-multi-octave (ngesiqhelo i-2:1 okanye ngaphezulu), ii-antenna ze-horn zisebenza njengemigangatho yesalathiso kwiI-antenna ye-11dBiiinkqubo zokulinganisa uluhlu.
I-Antenna ye-Broadband Horn (0.5-6GHz, 11dBi)
I-Antenna yeempondo ezimbini zeBroadband Polarized Horn （0.8-12GHz，11dBi)
I-Antenna ye-Broadband Horn （0.6-6GHz, 11dBi)
RF MisoIimveliso zothotho lwe-11dbi
Iimpawu zeMisebe echanekileyo:
Uzinzo lobubanzi bebheyimu ≤ ±2° kwi-bandwidth yokusebenza
Ucalucalulo lwe-cross-polarization > 25dB
I-VSWR < 1.25:1 ilungisiweibrashi ye-vacuumukwenziwa
Ukunyaniseka kwesakhiwo:
Ii-alloy ze-aluminium zodidi lomkhosi ezine-<5μm uburhabaxa bomphezulu
Ukutywinwa okufudumeleyo ukuze kusetyenziswe imeko-bume enzima (-55°C ukuya ku-+125°C)
Uhlalutyo lwezicelo:
Iinkqubo zeRadar:
Iradar yePESA: Isebenza njengesixhobo sokuphakela ii-arrays ezingasebenziyo
I-AESA Radar: Isetyenziswa ekulinganisweni kwe-subarray kunye novavanyo olukufutshane nentsimi
Iinkqubo zokulinganisa:
Umgangatho wokufumana inzuzo ephambili kwiUvavanyo lwe-antenna ye-RFizixhobo
Ukuqinisekiswa kobubanzi bebala elikude
Uvavanyo lwe-EMI/EMC ngokwe-MIL-STD-461G nganye
Iinkqubo zoNxibelelwano:
Ukutya kwesitishi somhlaba sesathelayithi
Iikhonkco ze-microwave eziqala kwindawo ukuya kwenye
Ukulinganiswa kwesitishi sesiseko se-5G mmWave
Uvavanyo lokuthelekisa:
Nangona kukho ezinye ii-antenna, uqwalaselo lweempondo luhlala lulawula ngenxa yezi:
Umlinganiselo weendleko/wokusebenza ophezulu
Ukulandeleka kokulinganiswa okusekwe
Ukuthembeka okuqinisekisiweyo (>100,000 hr MTBF)
Isiphelo:
Indibaniselwano eyahlukileyo ye-antenna yophondo yokuqikelelwa kwe-electromagnetic, ukuqina koomatshini, kunye nokuphindaphinda kokulinganisa kuqinisekisa ukuba iyaqhubeka nokuxhaphaka kubunjineli be-microwave. Ukuqhubela phambili okuqhubekayo kwi-vacuum brazing kunye ne-accurate machining kuphucula ngakumbi ukusebenza kwayo kwiinkqubo zesizukulwana esilandelayo.
Iireferensi:
Umgangatho we-IEEE 149-2021 (Iindlela zoVavanyo lwe-Antenna)
I-MIL-A-8243/4B (I-Antenna yeempondo zoMkhosi)
