In an RF antenna having a planar radiating element disposed adjacent to a ground plane, one or more metasolenoids are disposed between the radiating element and the ground plane. As such, the magnetic flux through the metasolenoids interacts with the radiating element and the ground plane, widening the bandwidth of the antenna. Each of the metasolenoid comprises a stack of split-ring resonators co-axially aligned. The gap in each split-ring resonator is oriented differently from the gap in the adjacent split-ring resonator. The use of metasolenoids disposed between the radiating element and the ground plane does not increase the volume of the radiating element.
