Abstract
The present invention provides an antenna miniaturized topology that is based on the implementation of a conductive loading on a quadrifilar helix antenna. This may be achieved by connecting the tip of the four helical arms to end members which may be circular planar conductors. The miniaturization of the antenna may be further enhanced by incorporating a dielectric material in the space between the four arms.
