Mhinduro pfupi:Antena yelog periodic iantenna inotungamira broadband yakavakwa kubva muzvikamu zvakasiyana-siyana zvemaelement ane radiating. Mapoka akasiyana eelement anotanga kushanda nemagetsi pamafrequencies akasiyana, zvichibvumira antena imwe kuchengetedza impedance inobatsira uye hunhu hwemwaranzi mubhendi rese rekushanda. Antena dzelog periodic dzinoshandiswa zvakanyanya pakuongorora EMI/EMC, kutarisa spectrum, kuyerwa kweantena, kutsvaga nzira uye masisitimu eRF ebroadband.
Chii chinonzi log periodic antena?
A antenna yenguva nenguva yelog, inowanzo pfupikiswa seLPA, imhuri yeantenna isingadyidzani nema frequency ine geometry inochinja kuita logarithmic pattern inodzokororwa. Chimiro chakajairika ilog periodic dipole array (LPDA), iyo inoshandisa zvinhu zve dipole zvehurefu hwakasiyana zvishoma nezvishoma uye nzvimbo dzakatenderedza boom inotsigira.
Kusiyana neantenna ine bhandi rakatetepa rakagadzirwa rakatenderedza kureba kwe resonant imwe chete, LPDA inoshandisa zvinhu zvakayerwa kuti ifukidze mabhendi ema frequency akasarudzwa. Pa frequency ipi neipi inoshanda, boka rezvinhu zviri pedyo ne resonance chete ndiro rinonyanya kubatsira mukupenya kwemwaranzi. Dunhu iri rinonzinzvimbo inoshandaSezvo frequency ichichinja, nzvimbo inoshanda inofamba ichitevedza array.
Antena yeLog Periodic Inoshanda Sei?
Zviyero zvezvinhu zviri pedyo zvine chekuita nechikero, chinowanzomiririrwa nebhii rechiGiriki rekuti tau. Kureba kwezvinhu, nzvimbo uye zvimwe zviyero zvinotevera hukama hwakaenzana. Nekuti chimiro chinodzokorora nemagetsi kana frequency ichichinja nechiyero chimwe chete, input impedance uye maitiro emwaranzi zvinogona kuramba zvakagadzikana pamusoro pebhandi rakakura.
Zvinhu zvakareba zvinotsigira chikamu chemafrequency akaderera chenzvimbo yekushanda, nepo zvinhu zvipfupi zvichitsigira chikamu chemafrequency akakwira. Simba rinotamiswa kuburikidza nehurongwa hwekudyisa hwakaringana, uye hukama hwechikamu pakati pezvinhu zviri pedyo hunogadzira danda rekutungamira. Kuwana chaiko, hupamhi hwebeam, chiyero chekumberi-kumashure uye kuenderana kweimpedance zvinoenderana nejometri yakadzama, chimiro chekutsigira, nzvimbo yekudyisa uye nzvimbo yekuisa.
Hunhu Hunokosha hweKushanda
