Antena Yoyang'ana Molunjika ya ANT0104HP Yokhala ndi Polarized Omnidirectional Antenna
| Mtsogoleri-mw | Chiyambi cha Antena Yoyang'ana Molunjika Yokhala ndi Ma Polarized Omnidirectional |
Tikubweretsa antenna ya Chengdu lead microwave Tech., (leader-mw) yolunjika mopingasa, yankho labwino kwambiri la mphamvu ya ma signali komanso kufalikira kwa malo aliwonse. Pogwiritsa ntchito ukadaulo wapamwamba komanso uinjiniya wosayerekezeka, antennayi ndi yabwino kwambiri pa ntchito zosiyanasiyana kuphatikizapo kulumikizana popanda zingwe, kuwulutsa ndi kulumikizana kwa IoT.
Ma antenna athu ozungulira mopingasa ali ndi kapangidwe kokongola komanso kolimba koyenera kuyikidwa mkati ndi kunja. Ndi luso lake lozungulira mopingasa, antenna imapereka kuphimba kwa madigiri 360, kuonetsetsa kuti chizindikirocho chili cholimba komanso chodalirika pamalo ambiri. Kaya mukufuna kukulitsa kulumikizana m'nyumba zamalonda, m'malo okhala anthu ambiri kapena m'malo opezeka anthu ambiri, antenna iyi ndiye yankho labwino kwambiri.
Chimodzi mwa zinthu zazikulu za ma antenna athu ozungulira mopingasa ndi mawonekedwe awo a kuwala kopingasa. Kapangidwe kake kapadera kameneka kamalola antenna kutumiza ndi kulandira zizindikiro m'njira zinazake, zomwe zimathandiza kuchepetsa kusokoneza ndi kukulitsa mphamvu ya zizindikiro. Izi zimapangitsa kuti ikhale chisankho chabwino kwambiri m'malo omwe khalidwe la chizindikiro ndi kusinthasintha kwake ndizofunikira kwambiri.
Mwachidule, Antenna ya ANT0104HP Yoyang'anira Zinthu Zonse ndi njira yabwino kwambiri yolumikizirana ndi mafoni ndi opanda zingwe. Ndi kuyika kwake kosavuta, kufalikira kwa madigiri 360, RF yotakata, komanso kapangidwe kolimba, antenna iyi ili ndi zonse zomwe mukufunikira kuti mukhale olumikizidwa m'dziko lamakono lomwe likuyenda mwachangu.
Musakhutire ndi ntchito yofooka - sankhani antenna ya ANT0104HP ndipo muwone kusiyana kwanu. Kaya ndinu kampani yopereka mauthenga, mwini bizinesi, kapena munthu amene akufuna kulumikizana kwabwino, antenna ya ANT0104HP imakuthandizani.

Nanga bwanji za ma coefficients a antenna?
Itha kugwiritsidwa ntchito poyesa mphamvu ya field pamalo a antenna, zomwe zimachitika kawirikawiri m'munda wa EMC. Voltage yotulutsa antenna imatha kuyezedwa ndi spectrometer.
Ingagwiritsidwe ntchito poyesa kuchuluka kwa antenna, ndipo ubale pakati pa antenna coefficient K ndi kulandira kuchuluka kwa antenna G ukhoza kukhazikitsidwa kudzera mu mathematical derivation:
Ndikofunikira kudziwa kuti pa antenna yogwira ntchito, coefficient yowerengedwa ndi antenna gain ilibe gawo la chidziwitso (lomveka bwino mu kuchuluka kwa chidziwitso chogawa kwa antenna beam), chifukwa tingathe mwa kusintha antenna yogwira ntchito ya amplifier gain coefficient ya antenna ndi yaying'ono kwambiri, kotero kukankhira kuti mupeze gain kungakhale kosatha, mwachiwonekere sizingatheke.
