We provide for the first time the experimental characterization of a planarly fed ultrawideband leaky lens antenna. The paper includes the description and the experimental characterization of two antenna prototypes with radiating element realized in printed circuit board technolo

Rigorous equivalent circuits representing the unit cell of
a connected array in transmission and reception are
derived in this paper. These equivalent networks are not
based on reciprocity but on Green¿s functions. Thus, all
components have well identified and physically

Most phased arrays are designed using infinite array
theory. However, when finiteness is included, edge
effects perturb their behaviour. Truncation effects can
become dominant especially in broadband arrays, which
are characterized by strong mutual coupling between
neighbouring e

To demonstrate the ultra-wide bandwidth performance while retaining manageable lens dimensions, 12 GHz has been chosen as lowest operating frequency. The planar feed has been realized in standard printed circuit board (PCB) technology. The matching layers reduce the reflection at

In this contribution we introduce the use of the UWB
leaky lens antenna as an improved photo-conducting
emitter for a THz time domain system. The UWB
antenna presents nearly constant impedance and
directive symmetric patterns over a decade of frequency
bandwidth. Currently, we ar
