Abstract
An antenna array having a central active element and a plurality of passive elements surrounding the active element is disclosed. A dielectric substrate or other slow wave structure is disposed radially outwardly from the passive elements for slowing the radio frequency waves so as to increase the antenna directivity by reducing the amount of energy radiated in the elevation direction.
