I-ANT0025PO I-Antenna ye-Log-periodic ebanjwe ngesandla
| Inkokeli-mw | Intshayelelo ye-Log-Periodic Antenna ebanjwe ngesandla |
Ukwazisa iCheng du leader i-mcrowave Tech.,(inkokeli-mw) i-eriyali ephathwa ngesandla ye-log-periodic, esona sisombululo sokwandisa amandla esignali kunye nokugubungela kwi-800 ukuya kwi-9000 MHz uluhlu lwamaza.Le antenna icwengileyo kodwa inamandla yenzelwe ukuxhasa iselula, iPCS, LTE, 4G LTE kunye neWifi/WiMAX frequency bands, iyenza ibe sisixhobo esibalulekileyo kuye nabani na ofuna unxibelelwano olungenazingcingo oluthembekileyo nolusebenza kakhulu.
I-antenna ye-log-periodic ephathwayo ifaka i-6 dBi i-flat gain, igubungela i-L/S/C/X ngokuchaneka okuphezulu kunye nokuchaneka, iqinisekisa ukuba uhlala uqhagamshelwe kungakhathaliseki ukuba uphi na.Eyodwa kule eriyali luyilo lwayo oluthe nkqo kunye noluthe tyaba lwelog-periodic, ebonelela ngokuguquguquka okungazange kubonwe ngaphambili kunye nokulungelelanisa ukuhlangabezana neemfuno zakho ezithile kunye nokusingqongileyo.
Idizayinelwe ukuqina kunye nokusebenza, i-eriyali ye-log-periodic ephathwayo ibonakalisa amandla aphezulu, ilahleko ephantsi yeplastiki ebunjiweyo yeradome eqinisekisa ukuba inokumelana neemeko ezinzima kwaye iqhubeke nokuhambisa umsebenzi obalaseleyo.Ukubamba kwepistol yayo ejikelezayo yongeza ngakumbi ekululameni nasekusebenziseni ngokulula, kukuvumela ukuba uhlengahlengise ngokulula i-antenna ukuze wenze ulwamkelo lophawu.

Inkcazo yezibalo ye-eriyali i-coefficient K ilandelayo:
Iintsingiselo zeparameter nganye zezi zilandelayo:
E: ukuqina kwebala kwindawo yendawo ye-eriyali efumanayo, kwiyunithi ye-V/m;
V: ixabiso lombane elifunyenwe lizibuko le-eriyali elifumanayo, kwiyunithi ye-V.
Ifomyula yokubala ye-eriyali i-coefficient echazwe kwi-logarithm ilandelayo:
Ukusetyenziswa kweLog-periodicDipoleAntenna
(1) Ikakhulu isetyenziswa kwi-ultra-short wave band, inokusetyenziswa njenge-eriyali yonxibelelwano lwamaza amaza kunye namaza aphakathi, i-eriyali yosasazo yosasazo olufutshane.Ii-eriyali zeLog-periodic zinokusetyenziswa njengezondla ii-eriyali ezibonisa i-microwave.Ingasetyenziselwa imisebenzi kanomathotholo engaqhelekanga kunye nebhendi yabemi, kunye nophando lwezenzululwazi kunye nokubeka iliso.
(2) I-Antenna ye-Log-periodic Dipole, iyakwazi ukugcina iipateni zemitha ezihambelanayo kuluhlu olubanzi lweefrikhwensi, zibenza zibe luncedo kwizicelo apho ii-eriyali kufuneka zikwazi ukusebenza kwiibhendi zamaza amaninzi ngaphandle kohlengahlengiso olukhulu okanye uhlengahlengiso.
