## Abstract

A dielectrically loaded printed antenna element is described. The antenna element includes at least one conductive arm supported on a substrate. The conductive arm is dielectrically loaded with at least one high dielectric material that is configured to provide spatial coverage of the conductive arm. An antenna array structure is also described that includes at least a first dielectrically loaded antenna element for transmitting and a second dielectrically loaded antenna element for receiving. The transmitting antenna element is aligned orthogonal to the receiving antenna element to further reduce interference.
