Abstract

Leaky lens antennas are linearly polarized directive antennas constituted by long slots etched on a ground plane that separates a dense dielectric, shaped to form a lens, from free space. These antennas are characterized by significant directivity, very low dispersion and they are suited to be integrated with the receive modules. These properties arise from the particular leaky wave radiation mechanism that these antennas exploit. In this contribution, the ultra-wide band version of the antenna described in [4] is presented. © 2006 EuMA.
