Second order semi-circles are added to the dipole arms which results in lateral size reduction of 23% and 8% with respect to standard LPDA and LPDA with first order semi-circle iteration respectively. Measurement and simulation results demonstrate that the antenna has a wide range of operating frequency from 0.87 GHz to 2.55 GHz and shows better gain variation than reference LPDAs.Englishinfo:eu-repo/semantics/closedAccessLog periodic antenna, wide-band, printed antenna, size-reducedPrinted AntennaWide-bandSize-reducedLog Periodic AntennaConference Object
