Non-dispersive, UWB Leaky lens antenna for millimeter and sub-millimeter wave frequencies

Enhanced Leaky lens antennas provide new opportunities for the development of wireless links over extremely large bandwidths without dispersions. In this contribution the potentials in this respect are presented. We provide the experimental characterization of a planarly fed ultra-wideband leaky lens antenna including a brief description of two antenna prototypes with radiating elements realized in printed circuit board technology. The impedance parameters and the radiation patterns of the antennas have been measured, showing excellent pattern quality and efficiency. The link between two antennas has then been characterized in the frequency and time domains in terms of mutual coupling impulse response, respectively.
