Abstract
In this work the concept of Artificial dielectric layers (ADL) has been utilized for the design of integrated slot antennas. ADL possess inherent property of enhancing the dielectric constant of the host dielectric materials, over extremely wide frequency ranges. They are realized by means of periodic metallic stratifications in a standard dielectric substrate. For the proof of concept, ADL have been used as an add-on component between a standard dual slot antenna and a dielectric lens. More than an octave of -10 dB impedance bandwidth has been achieved. The far-field radiation patterns are usable over approximately 60% of the impedance bandwidth.
