Non dispersive antenna array architectures for THz sensing systems:
Connected leaky wave slots
The frequency bandwidth is possibly the only resource widely available in the THz spectrum which is actually underused. However, theoretical and technological breakthroughs are needed in order to exploit this bandwidth for the realization of truly large imaging cameras in the THz

In this work we describe an effective strategy for the avoidance of common-mode resonances excited in a printed array of loaded dipoles with inherent filtering properties (filtenna). Previous works demonstrated that, for E-plane scanning, such resonances occur due to the unbalanc

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

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
