The widths of dipole elements are optimized to increase the bandwidth. A study of coaxial cable position is included in order to improve the antenna behavior. The measured return loss is lower than -15 dB from 2.1 to 4.3 GHz. The measured gain varies between 6 and 7 dBi. The measurements, including input impedance, gain and radiation patterns, and simulations are in agreement. %G English %2 https://univ-rennes.hal.science/hal-01068655/document %2 https://univ-rennes.hal.science/hal-01068655/file/Low_Return_Loss_Printed_Log_Periodic_Dipole_Antenna_accepted.pdf %L hal-01068655 %U https://univ-rennes.hal.science/hal-01068655 %~ CEA %~ UNIV-NANTES %~ UNIV-RENNES1 %~ CNRS %~ INSA-RENNES %~ IETR %~ IETR_SRC %~ STATS-UR1 %~ DAM %~ UR1-HAL %~ UR1-MATH-STIC %~ UR1-UFR-ISTIC %~ IETR-CUTE %~ IETR-ADH %~ TEST-UNIV-RENNES %~ TEST-UR-CSS %~ UNIV-RENNES %~ INSA-GROUPE %~ UR1-MATH-NUM %~ IETR-STAR %~ IETR-SUMIT %~ NANTES-UNIVERSITE %~ UNIV-NANTES-AV2022
