Miniaturization of an UWB Dual-Polarized Antenna
Résumé
For some UWB applications (short range radars,
medical imaging), it has been shown that the use of an antenna
that supports a dual-polarization can enhance their accuracy.
However, the size of classic UWB dual-polarized antennas makes
their integration into small devices difficult. As size became
crucial, miniaturization techniques have been previously investigated
in an UWB context. In this paper, we aim to provide an
electrically-small UWB antenna with a dual-polarized radiation
pattern. A planar miniaturization technique has been investigated
on a dual-polarized sinuous antenna. A size reduction of 32%
has been achieved without compromising on either bandwidth or
radiation performances.
