Abstract
An antenna may include a volume polarization current radiator and a feed network. The volume polarization current radiator, includes a dielectric solid (such as a dielectric strip), and a plurality of closely-spaced excitation elements (), each excitation element () being configured to induce a volume polarization current distribution in the dielectric solid proximate to the excitation element when a voltage is applied to the excitation element. The feed network is coupled to the volume polarization current radiator. The feed network also includes a plurality of passive power divider elements () and a plurality of passive delay elements (d-d) coupling the first port () and the plurality of second ports (), the plurality of power divider elements () and the plurality of phase delay elements (d-d) being configured such that a radio-frequency signal that is applied to the first port () experiences a progressive change of phase as it is coupled to the plurality of second ports () so as to cause the volume polarization current distribution to propagate along the dielectric solid.
