TheLog Periodic Antenna(LPA) yakatsanangurwa muna 1957 uye imwe mhando yeantenna isiri-frequency-variable.
Zvinobva pane inotevera pfungwa yakafanana: kana antenna ikashandurwa zvinoenderana neimwe proportional factor τ uye ichiri yakaenzana nechimiro chayo chepakutanga, antenna ine kuita kwakafanana kana chinhu chiri f uye τf. Kune akawanda mafomu e log periodic antennas, pakati peiyo Log Dipole Antenna (LDPA) yakatsanangurwa muna 1960 ine yakanyanyisa bandwidth maitiro uye yakapusa chimiro, saka yakashandiswa zvakanyanya mumapfupi-pfupi, ekupedzisira-pfupi uye microwave mabhendi.
Iyo log periodic antenna inongodzokorora iyo radiation pateni uye impedance maitiro nguva nenguva. Nekudaro, kune antenna ine chimiro chakadaro, kana τ isiri pasi pe1, shanduko yehunhu hwayo mukati meimwe denderedzwa idiki kwazvo, saka inongozvimiririra kune frequency.
Kune akawanda marudzi e log periodic antennas, anosanganisira log periodic dipole antennas uye monopole antennas, log periodic resonant V-shaped antennas, log periodic spiral antennas, nezvimwewo, pakati peiyo inonyanya kuzivikanwa iyo log periodic dipole antenna.
Seye Ultra-wideband antenna, iyo bandwidth yekuvhara yakafara kwazvo, kusvika 10: 1, uye inowanzoshandiswa kukwidziridza chiratidzo, kugovera kwemukati uye kufukidzwa kwechiratidzo chekusimudza. Pamusoro pezvo, iyo logarithmic periodic antenna inogona zvakare kushandiswa sesosi yekudyisa yemicrowave reflector antennas. Sezvo nzvimbo inobudirira inofamba nehuwandu hwekushanda, kutsauka pakati penzvimbo inoshanda uye kutarisa mune yese yekushanda frequency band inofanira kunge iri mukati mehutano hunobvumirwa kushivirira panguva yekuisa.
