“…It extends the system modeling proposed in the case of the single UWB antennas [19] for the UWB arrays. Indeed, it is acknowledged that for evaluating antennas with baseband pulse excitations the most general antenna descriptor is the antenna impulse response, and thus, the UWB antennas can be considered as Linear Time Invariant (LTI) systems characterized by transfer functions or associated impulse responses.…”

Abstract-This paper proposes some approaches to model Ultra Wideband (UWB) antenna arrays. Based on the array factor, often stipulated as not adapted for the description of the properties of UWB arrays in the literature, an analytical expression of the beampattern is developed. The achieved results are coherent with other formulations and empiric studies proposed in the literature. Furthermore, a time-frequency modeling of UWB antenna arrays is proposed using the concept of array factor and antenna effective length.

Abstract-A compact ultra-wideband planar monopole antenna with a notched band at WLAN frequencies is presented. The antenna is fed using a finite ground coplanar waveguide and has a structure consisting of stair-shaped radiator and ground plane. The notched band is implemented by cutting two symmetrical narrow slits from the ground plane. The antenna is fabricated on a substrate with a dielectric constant of 4.4 and has a compact size of 18 × 26 × 1.6 mm 3 . Experimental and simulation results of the fabricated antenna are found to be in good agreement. The antenna achieves an average gain of 3 dBi and efficiency of more than 80% over the operational band. Time domain analysis, which includes the group delay response and fidelity calculation, implies that minimal distortion is introduced by the proposed antenna which makes it suitable for portable pulsed UWB systems.

“…The standard reference antenna should not add significant dispersion when receiving the incident pulse and any effects are eliminated by de-embedding [19] - [21]. A bore-sight directional tapered slot antenna was selected for the nondispersive TD performance in receive mode.…”

Abstract-Miniaturized monopole and dipole antenna designs are reported with performances optimized for Ultra Wideband pulsed radio applications. The geometries are created using Bézier spline shapes, which have been refined with a genetic algorithm to simultaneously take account of both frequency-and time-domain criteria.Time-domain measurements of ultra wideband antennas with uniformly distributed energy across the full 3.1 -10.6 GHz mask are reported for the first time and validate a new approach to minimization of pulse dispersion effects in the antenna designs.Index Terms-optimization methods, ultra wideband antennas, dipole antennas, time domain measurements.
