Ma Antennas a FM

Mndandanda wa antenna a FMUSER akuphatikiza tinyanga zambiri zotsika mtengo zozungulira elliptical polarization FM ndi tinyanga za dipole FM ndi kuphatikiza kwazinthu za FM, zomwe ndi imodzi mwazinthu zofunika kwambiri payankho la FMUSER. Mlongoti wa dipole ndi mlongoti wa wailesi wopangidwa ndi aluminiyamu, mkuwa, ndi machubu amkuwa, ndipo pakati pake ali ndi zida zoyendetsera. Amakhala ndi zitsulo ziwiri zazitsulo za ndodo, zofanana ndi collinear (mu mzere wina ndi mzake), ndi mtunda waung'ono pakati pawo. Mlongoti wa dipole ndi mtundu wofunikira kwambiri wa mlongoti wa radiofrequency ndipo wakhala ukugwiritsidwa ntchito kwambiri potumiza ndi kulandila mawayilesi. Mlongoti wozungulira polarized ali ndi makhalidwe osungira mawonekedwe, opepuka, ang'onoang'ono komanso otsika mtengo, choncho ali ndi udindo wofunikira kwambiri pakulankhulana opanda zingwe. Mndandanda wa tinyanga za RF FM uli ndi mphamvu yokhazikika yotumizira ma audio, ndipo ma frequency angapo amatha kusinthidwa ndikusankhidwa. Kuyika ndi ntchito ndizosavuta. Chifukwa cha mitundu yosiyanasiyana ya polarization, mndandanda wathu wa antenna wa FM uli ndi kuthekera kosiyanasiyana. Kuchuluka kwa zigawo za mlongoti wa FM kumayambira 1 mpaka 8. Mitundu yosiyanasiyana ya tinyanga za FM ikhoza kugawidwa ndi ma transmitters a FM okhala ndi mphamvu kuchokera ku 0.1W mpaka 10kW. Chifukwa chakuchita bwino komanso kutsika mtengo, ma tinyanga a FM awa amakondedwa ndi okonda wailesi ya FM, mainjiniya a wailesi ya FM, ndi magulu ena achidwi kapena akatswiri. Nthawi yomweyo, imagwiritsidwanso ntchito kwambiri pamasinthidwe osiyanasiyana amawayilesi amtundu wa FM kapena mawayilesi apawailesi a FM, monga mawonedwe amakanema, ma drive-mu tchalitchi, kuyesa kuyesa kwa nucleic acid, zazikulu ndi zazing'ono. kapena zosiyanasiyana masewera moyo ndemanga, etc.
