In this paper we propose a new structure of antenna that is self-directional (without reflector) and has a low sensitivity to its surrounding. The direction of the radiation pattern can be electrically commutated on one side or on the other side of the antenna. The polarization can be chosen right or left circular. The size of the antenna can be strongly reduced. Furthermore, This antenna can be used at low frequency because high-permittivity dielectrics are not used for reducing the size.
