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 meaningf ...
