433Mhz pcb antenna 400-490mhz poyankhulana

Kuyambitsa zatsopano zaukadaulo zolankhulana - 400-490mhz antenna. Ndi mapangidwe ake apadera komanso mawonekedwe am'mphepete, antenna iyi yakhazikitsidwa kuti isinthe momwe mumalumikizirana.

Kutengera mtundu wa 400-490mhz, ma antenna awa amapereka malo ambiri ophunzitsira kuyankhulana. Kaya mukutenga nawo mbali mu katswiri kapena kulankhulana patokha, ma antenna amatsimikizira kuti kufalikira koyenera komanso koyenera.

Ndi vswr wa <= 2.0, antenna uyu amatsimikizira kutayika kocheperako ndikupereka magwiridwe antchito apadera ngakhale m'malo ovuta. Izi zikutanthauza kuti mutha kudalira mawonekedwe awa kuti mumve zomveka bwino komanso zosasinthika nthawi zonse.

Kuyika kwa Antenna Kusokoneza kwa 50ω kumathandizira kuyenderana kopitilira zida zoyankhulirana. Mutha kulumikizidwa mopanda nsabwe izi ku zida zanu popanda zovuta zilizonse.

Khalani ndi vuto lalikulu lamphamvu ndi phindu la 3dbi. Izi zikuwonetsetsa kuti zizindikiro zanu ndi zamphamvu komanso zokhazikika, kulola kumveka bwino. Nenani zabwino za kufooka komanso kosadalirika - sangalalani ndi kulumikizana kopanda malire ndi 400-400Mhzznna.

Zopangidwa kuti mugwiritse ntchito mosavuta, antenna ili ndi polarization yomwe ingasinthidwe kukhazikitsa ndikuiyika. Tsopano, mutha kukhazikitsa antenna mwachangu komanso moyenera, kupulumutsa nthawi ndi kuyesetsa.

Kulemera gru gramu yokha, antenna iyi ndi yopepuka komanso yotsika, kupangitsa kukhala kosavuta kunyamula kulikonse komwe mungapite. Magawo ake a Lxwt Connensions a 32x7x0.4mm amapanganso kukhala yabwino kukhazikitsa mwanzeru.

Kuphatikiza apo, lencna imabwera ndi kutalika kwa 10 cm. Komabe, ngati mukufuna kutalika kokhazikika, titha kukwaniritsa zosowa zanu. Cholinga chathu ndikukupatsirani njira yolumikizira yomwe imakwaniritsa zofunikira zanu.

Pomaliza, athu 400-490mzz amaphatikiza kukhazikika, magwiridwe antchito, komanso osavuta kugwiritsa ntchito. Ndi mtundu wake wokulirapo, mtundu wa chizindikiro chapadera, komanso kutalika kokhazikika, ma antenna ndi chisankho chabwino pazomwe mumayankhulana nazo konse. Khalani olumikizidwa ngati kale ndi wathu wodalirika komanso wothandiza 400-490mhz antenna.
