The notch antenna is loaded with a variablemetal/insulator/metal (MIM) capacitor and is achieved by a monolithic method. The MIM capacitance is3.7 pF, which results in a resonant frequency of 670 MHz compared to 2.25 GHz for the unloadedsimulated antenna; the resulting miniaturization rate is 70%. The characterization of the antennaprototype shows a frequency tunable rate of 14.5% under an electricfield of 375 kV/cm, with a tunabilityperformance h = 0.04. %G English %2 https://hal.science/hal-01119380/document %2 https://hal.science/hal-01119380/file/Miniaturized%20and%20reconfigurable%20notch_accepted.pdf %L hal-01119380 %U https://hal.science/hal-01119380 %~ CEA %~ UNIV-NANTES %~ UNIV-RENNES1 %~ CNRS %~ INSA-RENNES %~ IETR %~ IETR_SRC %~ IETR_MF %~ STATS-UR1 %~ CENTRALESUPELEC %~ DRT %~ UR1-HAL %~ UR1-MATH-STIC %~ UR1-UFR-ISTIC %~ IETR-CUTE %~ IETR-FUNMAT %~ IETR-ADH %~ TEST-UNIV-RENNES %~ LETI %~ TEST-UR-CSS %~ UNIV-RENNES %~ INSA-GROUPE %~ CEA-GRE %~ UR1-MATH-NUM %~ IETR-STAR %~ NANTES-UNIVERSITE %~ UNIV-NANTES-AV2022 %~ IETR-NANTES
