IyoAntena yePeriodic Log(LPA) yakatangwa muna 1957 uye imwe mhando yeantenna isingachinji-chinoshanduka.
Yakavakirwa papfungwa yakafanana inotevera: kana antenna ikachinjwa zvichienderana nechimwe chinhu chinoenderana ne τ uye ichiri yakaenzana nechimiro chayo chepakutanga, antenna ine mashandiro akafanana kana chinhu chiri f uye τf. Kune mhando dzakawanda dze log periodic antennas, pakati padzo iyo Log Dipole Antenna (LDPA) yakataurwa muna 1960 ine hunhu hwakakura hwebandwidth uye chimiro chiri nyore, saka yakashandiswa zvakanyanya muma shortwave, ultra-shortwave uye microwave bands.
Antena ye log periodic inongodzokorora patani yemwaranzi uye hunhu hwe impedance nguva nenguva. Zvisinei, kune antena ine chimiro chakadaro, kana τ isiri pasi pe1, shanduko yehunhu hwayo mukati meimwe denderedzwa idiki kwazvo, saka hainyanyi kuenderana nefrequency.
Kune mhando dzakawanda dze log periodic antennas, dzinosanganisira log periodic dipole antennas uye monopole antennas, log periodic resonant V-shaped antennas, log periodic spiral antennas, nezvimwewo, pakati padzo inonyanya kuzivikanwa i log periodic dipole antenna.
Se antenna ine ultra-wideband, bandwidth coverage yakakura kwazvo, kusvika 10:1, uye inowanzoshandiswa pakuwedzera masignal, kugoverwa kwemukati uye kufukidza masignal eelevator. Pamusoro pezvo, logarithmic periodic antenna inogonawo kushandiswa senzvimbo yekudyisa ma antenna e microwave reflector. Sezvo nzvimbo inoshanda ichifamba nefrequency yekushanda, kutsauka pakati penzvimbo inoshanda uye chinangwa chiri muband yese yefrequency yekushanda kunofanirwa kunge kuri mukati mehuwandu hwekutsungirira hunobvumidzwa panguva yekuisa.
RF MISO's Model RM-DLPA022-7 iantenna ine polarized log periodic inoshanda kubva0.2 kusvika 2 GHz, Antena inopa7dBikuwana kwakajairika. Kanere yeVSWR ndiyo 2Rudzi. Machiteshi eRF eantenna inobatanidza N-Female. Antena iyi inogona kushandiswa zvakanyanya mukuona EMI, kurongeka, kuongorora, kuyera antenna gain uye pattern pamwe nemamwe mashandisirwo ayo.
RM-DLPA022-7
RF MISO'sMuenzanisoRM-LPA0033-6 is log nguva nenguva antenna inoshanda kubva0.03 to 3 GHz, Antena inopa 6dBi kuwana kwakajairika. Kanere yeVSWR ndiyo zvishoma pane2:1. Kan'antena yeRF madoko ariN-Mukadzichinongedzo. Antena inogona kushandiswa zvakanyanya mukuona EMI, kurongeka, kuongorora, kuyera antenna kuwana uye mapatani pamwe nemamwe minda yekushandisa.
RM-LPA0033-6
RF MISO'sMuenzanisoRM-LPA054-7 is log nguva nenguva antenna inoshanda kubva0.5 to 4 GHz, Antena inopa 7dBi kuwana kwakajairika. Kanere yeVSWR ndiyo 1.5 Rudzi. Kan'antena yeRF madoko ariN-Mukadzichinongedzo. Antena inogona kushandiswa zvakanyanya mukuona EMI, kurongeka, kuongorora, kuyera antenna kuwana uye mapatani pamwe nemamwe minda yekushandisa.

Kuti udzidze zvakawanda nezve antenna, ndapota shanyira:
