I-ANT0025PO I-Log-periodic Antenna ephathwa ngesandla
| Umholi-mw | Isingeniso Se-Log-Periodic Antenna Ephethwe Hand |
Sethula i-Cheng du leader i-mcrowave Tech.,(umholi-mw) i-antenna ye-log-periodic ephathwa ngesandla, ikhambi eliwujuqu lokukhulisa amandla esignali nokumbozwa kububanzi obungu-800 kuya ku-9000 MHz. Le antenna ehlangene kodwa enamandla yakhelwe ukusekela amabhendi eselula, i-PCS, LTE, 4G LTE kanye ne-Wifi/WiMAX, okuyenza ibe ithuluzi elibalulekile kunoma ubani odinga ukuxhumana okungenazintambo okuthembekile nokusebenza okuphezulu.
I-antenna ephathwa ngesandla ye-log-periodic antenna ifaka i-6 dBi flat gain, emboza i-L/S/C/X ngokunemba okuphezulu nokunemba, iqinisekisa ukuthi uhlala uxhumekile noma ngabe ukuphi. Ingqayizivele yale antenna idizayini yayo ye-log-periodic eshintshayo eshintshayo nevundlile, ehlinzeka ngokuguquguquka okungakaze kubonwe kanye nokuzivumelanisa nezimo ukuze kuhlangatshezwane nezidingo zakho ezithile nendawo.
Idizayinelwe ukuqina nokusebenza, uthi oluphathwayo lwe-log-periodic oluphathwa ngesandla lufaka i-radome ebunjiwe yepulasitiki enamandla amakhulu, elahlekelwa kancane eqinisekisa ukuthi ikwazi ukumelana nezimo ezinzima futhi iqhubeke nokuletha ukusebenza okuvelele. Ukubamba kwayo kwesibhamu esizungezayo kwengeza futhi ekululameni nasekusebenziseni kalula, okukuvumela ukuthi ulungise kalula i-antenna ukuze wenze ukwamukela kwesignali ngokugcwele.

Ukusetshenziswa kwe-Log-periodicDipoleAntenna
(1) Isetshenziswa kakhulu ku-ultra-short wave band, ingasetshenziswa futhi njenge-antenna yokuxhumana yamagagasi amafushane namagagasi aphakathi nendawo, i-antenna yokusakaza igagasi elifushane. Ama-antenna e-Log-periodic angasetshenziswa futhi njengeziphakeli zezimpondo ezibonisa i-microwave. Ingasetshenziselwa umsakazo we-ateur kanye nemisebenzi yomsakazo webhendi yezakhamizi, kanye nocwaningo lwesayensi nokuqapha.
(2) I-Dipole Antenna ye-Log-periodic, iyakwazi ukugcina amaphethini emisebe angaguquki phezu kwebanga elibanzi lamaza, okuwenza abe usizo ezinhlelweni lapho izimpondo zidinga ukusebenza kuwo wonke amabhendi amafrikhwensi amaningi ngaphandle kokulungiswa okukhulu noma ukuguqulwa.
