II-Antenna yePeriodic yeLog(LPA) yacetywayo ngo-1957 kwaye lolunye uhlobo lwe-antenna eguquguqukayo rhoqo.
Isekelwe kule ngcamango ifanayo ilandelayo: xa i-antenna iguqulwa ngokwe-factor ethile elinganayo τ kwaye isalingana nesakhiwo sayo sokuqala, i-antenna inokusebenza okufanayo xa i-factor ingu-f kunye no-τf. Kukho iintlobo ezininzi ze-antenna ze-log periodic, phakathi kwazo i-Log Dipole Antenna (LDPA) eyacetywayo ngo-1960 ineempawu ze-bandwidth ezibanzi kakhulu kunye nesakhiwo esilula, ngoko ke isetyenziswa kakhulu kwii-shortwave, ultra-shortwave kunye nee-microwave bands.
I-antenna ye-log periodic iphinda nje ipateni yemitha kunye neempawu ze-impedance rhoqo. Nangona kunjalo, kwi-antenna enesakhiwo esinjalo, ukuba i-τ ayingaphantsi kakhulu kune-1, utshintsho lweempawu zayo ngaphakathi komjikelo omnye luncinci kakhulu, ngoko ke ngokusisiseko ayixhomekekanga kwi-frequency.
Kukho iintlobo ezininzi zee-antenna ze-log periodic, kuquka ii-antenna ze-log periodic dipole kunye nee-antenna ze-monopole, ii-antenna ze-log periodic resonant V-shaped, ii-antenna ze-log periodic spiral, njl.njl., phakathi kwazo ezona zixhaphakileyo yi-antenna ye-log periodic dipole.
Njenge-antenna ye-ultra-wideband, i-bandwidth coverage ibanzi kakhulu, ukuya kuthi ga kwi-10:1, kwaye idla ngokusetyenziselwa ukukhulisa isignali, ukusasazwa ngaphakathi kunye nokugubungela isignali ye-elevator. Ukongeza, i-antenna ye-logarithmic periodic ingasetyenziswa njengomthombo wesondlo se-antennas ze-microwave reflector. Ekubeni indawo esebenzayo ihamba kunye ne-frequency yokusebenza, ukuphambuka phakathi kwendawo esebenzayo kunye nokugxila kuyo yonke i-frequency band yokusebenza kufuneka kube ngaphakathi koluhlu lokunyamezela oluvumelekileyo ngexesha lokufakwa.
I-RF MISOImodeli ye-RM-DLPA022-7 yi-antenna ye-log ene-Polarized ene-dual-Polarized esebenza kwi-0.2 ukuya kwi-2 GHz, I-antenna inikezela7dBiinzuzo eqhelekileyo. I-antenna ye-VSWR yi 2UhloboIiports ze-antenna RF zizixhumi ze-N-Female. I-antenna ingasetyenziswa kakhulu ekufumaneni i-EMI, ukujongwa, ukuhlaziya, ukulinganiswa kwe-antenna kunye nokulinganiswa kwepateni kunye nezinye iindawo zokusetyenziswa.
