I-antenna ye-Log periodic yi-antenna ebhekisa kwicala elinoluhlu olubanzi lwee-frequency zokusebenza. Ukwahluka kwayo kukwiimpawu zayo zombane, ezifana ne-impedance kunye neepatheni zecala, eziphindaphinda i-logarithmic kunye namaxesha athile kunye ne-frequency.

Iimpawu:

1. Iimpawu ze-Broadband: Le yeyona nzuzo iphambili. I-antenna ye-single log periodic ingagubungela uluhlu olubanzi kakhulu lweefrikhwensi (ezifana ne-10:1 okanye nangaphezulu), kwaye ingasebenza kwiibhendi ezininzi zeefrikhwensi ngaphandle kokulungisa.
2. Imitha ebhekisa kwicala: Inecala, njenge "totshi", egxila amandla kwicala elinye ukuze kukhutshwe umbane kwaye inokufumana ngcono imiqondiso evela kuloo ndlela, nto leyo ekhokelela ekuzuzeni okuphezulu kunye nokukwazi okunamandla okulwa nokuphazamiseka.
3. Iimpawu zesakhiwo: Zenziwe ngothotho lwee-oscillator zesinyithi ezinobude kunye nesithuba esahlukileyo, ubungakanani kunye nendawo yezi oscillator zilandela imithetho engqongqo ye-logarithmic periodic. I-oscillator ende kakhulu imisela i-frequency yokusebenza ephantsi, kwaye i-oscillator emfutshane imisela i-frequency yokusebenza ephezulu.
4. Umgaqo wokusebenza: Kwi-frequency ethile, yinxalenye kuphela "yeyunithi ye-resonant" ye-antenna evuselelwa ngempumelelo kwaye ithatha inxaxheba kwi-radiation, kwaye le ndawo ibizwa ngokuba "yi-effective zone". Xa i-frequency itshintsha, le ndawo isebenzayo iya kuhamba ibuyela umva kwisakhiwo se-antenna.

Izicelo:

1. Ukwamkelwa kweTV: Ii-eriyali zokuqala zokwamkelwa kweTV zangaphandle zazisetyenziswa kakhulu ngolu hlobo.
2. Ukubeka esweni uluhlu lwerediyo olujikelezayo.
3. Uvavanyo lokuhambelana kwe-electromagnetic: Isetyenziswa njenge-antenna yokudlulisa okanye yokwamkela kwigumbi elimnyama lokuvavanya ukukhutshwa kwemitha kunye nokukhuselwa kwemitha.
4. Unxibelelwano lwamaza amafutshane: Isetyenziswa njenge-antenna yonxibelelwano olubhekisa kwicala kwibhendi yamaza amafutshane.
5. Ukubeka esweni i-RF kunye nokufumanisa icala: Isetyenziselwa ukuskena kunye nokubeka esweni imiqondiso kuluhlu olubanzi lwamaza.

I-QualwaveIi-antenna ze-log periodic zibonelela ngeendawo ezijikelezayo ukuya kuthi ga kwi-6GHz, kunye nee-antenna ze-log periodic ezenziwe ngokwezifiso ngokweemfuno zabathengi.
