UWB antennas bandwidth makes them highly suitable for a number of applications. In surface penetrating radar (SPR) applications, which is the focus of our research, such a bandwidth range allows good signal penetration ability and fine space resolution for microwave imaging. In addition, it has been shown that the knowledge of the radiated...

The purpose of this letter is to model the three-dimensional radiation pattern of an ultrawideband antenna in near-field region. This compacting process can be established by combining spherical vector wave expansion and Cauchy methods. Spherical basis possesses the advantage of handling both radial and angular behavior, whereas the Cauchy...

This paper presents an application of the Matrix Pencil (MP) method to modelize UWB exponential Tapered Slot Antenna (ETSA) radiation performances. The determination of the 3D Impulse Response of Antenna (IRA) is performed starting from measured data. Using the Matrix Pencil method, we establish a compact model of the antenna. A new criterion...

This paper describes a linear combination of Spherical Vector Wave Expansion (SVWE) and Singularity expansion methods (SEM) to compress the radiation pattern of ultrawideband antennas and its application to Through-The-Wall (TTW) measurements. This process is applied and compared between simulated and experimental data in free space and in TTW...
