ANT0025PO Mlongoti Wogwira Pamanja Log-periodic Antenna
| Mtsogoleri-mw | Chiyambi cha Mlongoti Wogwirizira Pamanja wa Log-Periodic Antenna |
Kufotokozera Cheng du leader mcrowave Tech.,(mtsogoleri-mw) mlongoti wogwirizira m'manja nthawi yayitali, njira yabwino kwambiri yowonjezerera mphamvu zama siginecha ndi kufalikira kwa ma frequency a 800 mpaka 9000 MHz. Mlongoti wophatikizika koma wamphamvu uwu wapangidwa kuti uzithandizira ma cellular, PCS, LTE, 4G LTE ndi Wifi/WiMAX ma frequency band, ndikupangitsa kuti ikhale chida chofunikira kwa aliyense amene amafunikira kulumikizana kodalirika komanso kopanda zingwe.
Mlongoti wa m'manja wa log-periodic antenna amakhala ndi phindu la 6 dBi, lomwe limaphimba L/S/C/X mwatsatanetsatane komanso molondola kwambiri, kuwonetsetsa kuti mumakhala olumikizana kulikonse komwe mungakhale. Chapadera pa mlongoti uwu ndi mawonekedwe ake osinthika osunthika komanso opingasa a log-periodic, omwe amapereka kusinthasintha kosaneneka komanso kusinthika kuti akwaniritse zosowa zanu ndi chilengedwe.
Amapangidwira kuti azikhala olimba komanso kuti azigwira ntchito, mlongoti wa log-periodic wa m'manja uli ndi radome yopangidwa ndi pulasitiki yamphamvu kwambiri, yotayika pang'ono kuonetsetsa kuti imatha kupirira zovuta ndikupitiriza kupereka ntchito yabwino kwambiri. Kumangirira kwake kwa mfuti kumawonjezeranso kusavuta komanso kosavuta kugwiritsa ntchito, kukulolani kuti musinthe mlongoti kuti mukwaniritse bwino kulandila kwa siginecha.

Kugwiritsa ntchito kwa Log-periodicDipoleAntenna
(1) Imagwiritsidwa ntchito makamaka mu gulu lalifupi lalifupi, itha kugwiritsidwanso ntchito ngati mlongoti wolumikizana ndi mafunde amfupi ndi mafunde apakatikati, mlongoti wamafunde amfupi. Tinyanga ta Log-periodic zitha kugwiritsidwanso ntchito ngati zodyetsera za tinyanga ta microwave reflector. Itha kugwiritsidwa ntchito pawayilesi osaphunzira komanso ma wailesi amtundu wa nzika, komanso kafukufuku wasayansi ndi kuwunika.
(2) Log-periodic Dipole Antenna, amatha kusunga ma radiation osasinthika pama frequency osiyanasiyana, kuwapangitsa kukhala othandiza pamapulogalamu omwe tinyanga zimafunikira kugwira ntchito pama band angapo popanda kusintha kwakukulu kapena kusintha.
