Abstract: The miniaturization of antipodal Vivaldi antenna (AVA) based on high dielectric constant and magnetodielectric ferrite materials is studied. The basic parameters of antipodal Vivaldi antenna based on high dielectric and magnetodielectric materials (MDM) are compared. To miniaturize antenna size by higher factor it is used MDM ferrite with εr=μr=8 paremeters. The analysis shows that MDM based Vivaldi surface minimizes 4 times as compared with air-based Vivaldi antenna. The sizes of AVA are 120×120×1 (mm).
Keywords: miniaturization, antipodal Vivaldi antenna, electrically small antenna, ultrawideband antenna, magnetodielectric material, ferrite.
