XHUMANA MANJE

I-antenna ye-Log periodic iyi-antenna eqondisayo enobubanzi obubanzi bokusebenza. Ukuhluka kwayo kusezindaweni zayo zikagesi, njenge-impedance kanye namaphethini okuqondisa, aphinda i-logarithmically futhi ngezikhathi ezithile kanye nemvamisa.

Izici:

1. Izici ze-Broadband: Lena inzuzo yayo evelele kakhulu. Ilogi eyodwa ye-antenna ingamboza ububanzi befrikhwensi ebanzi kakhulu (efana no-10:1 noma ngaphezulu), futhi ingasebenza kumabhendi amafrikhwensi amaningi ngaphandle kokushuna.
2. I-Directional radiation: Inokuqondisa, "njenge-flashlight", egxilisa amandla ohlangothini olulodwa ukuze ikhishwe futhi ingathola kangcono amasignali asuka kuleyo ndlela, okuholela ekuzuzeni okuphezulu nekhono eliqinile lokulwa nokuphazamiseka.
3. Izici zesakhiwo: Ihlanganiswe uchungechunge lwama-oscillator ensimbi anobude obuhlukahlukene kanye nesikhala, ubukhulu kanye nendawo yalawa ma-oscillator alandela imithetho eqinile ye-logarithmic periodic. I-oscillator ende kunazo zonke inquma imvamisa yokusebenza ephansi, futhi i-oscillator emfushane inquma imvamisa yokusebenza ephezulu kakhulu.
4. Umgomo wokusebenza: Ngemvamisa ethile, ingxenye kuphela "yeyunithi ye-resonant" ye-antenna ejabula ngokuphumelelayo futhi ibamba iqhaza emisebeni, futhi le ndawo ibizwa ngokuthi "indawo esebenzayo". Uma i-frequency ishintsha, le ndawo esebenzayo izohamba iye emuva naphambili esakhiweni se-antenna.

Izicelo:

1. Ukwamukela i-TV: Izinti zangaphambi kwesikhathi zokwamukela i-TV yangaphandle zivame ukusebenzisa lolu hlobo.
2. Ukuqapha ububanzi berediyo yonke indawo.
3. Ukuhlolwa kokuhambisana kwe-electromagnetic: Kusetshenziswa njengothi oludluliselayo noma lokwamukela ekamelweni elimnyama ukuze kukhishwe imisebe kanye nokuhlolwa kokugonywa kwemisebe.
4. Ukuxhumana kwamagagasi amafushane: Kusetshenziswa njengothi lokuxhumana oluqondisayo kubhendi yegagasi elifushane.
5. Ukuqapha kwe-RF nokuthola isiqondiso: Isetshenziselwa ukuskena nokuqapha amasignali ebangeni elibanzi lefrikhwensi.

Qualwaveihlinzeka ngezimpondo zelogi ezikhava imvamisa yobubanzi obufika ku-6GHz, kanye nezimpondo zelogi ezenziwe ngokwezifiso ngokwezidingo zamakhasimende.
