This method is based on a coaxial line method for which a calibration technique is proposed to take into account the variations of the bias system. Measured permeability spectra are used to design a tunable antenna in VHF frequency band. © 2019 IEEE. %G English %L hal-02569540 %U https://hal-univ-rennes1.archives-ouvertes.fr/hal-02569540 %~ CEA %~ UNIV-BREST %~ UNIV-NANTES %~ INSTITUT-TELECOM %~ UNIV-RENNES1 %~ CNRS %~ UNIV-UBS %~ INSA-RENNES %~ IETR %~ SUP_IETR %~ ENIB %~ LAB-STICC %~ STATS-UR1 %~ CENTRALESUPELEC %~ DSV %~ DRT %~ UR1-HAL %~ UR1-MATH-STIC %~ UR1-UFR-ISTIC %~ IETR-CUTE %~ IETR-ADH %~ CEA-DRF %~ LETI %~ TEST-UR-CSS %~ UNIV-RENNES %~ INSA-GROUPE %~ CEA-GRE %~ INSTITUTS-TELECOM %~ TEST-HALCNRS %~ UR1-MATH-NUM %~ IETR-STAR %~ NANTES-UNIVERSITE %~ UNIV-NANTES-AV2022
