“…The conception of the Valentine antenna has been performed using a finite-difference time-domain (FDTD) software. The FDTD method based on a discrete form of Maxwell's equations is a suitable tool for an electromagnetic analysis of traveling wave antennas: it takes all the propagation and radiation modes into account, and leads directly to the time evolution of the radiated field [6]. The metallic elements are defined as perfect metallic plates without thickness.…”

We propose a novel ultrawideband (UWB) antenna designed specially for transient UWB radar applications. This work is a part of a new project concerning an optoelectronic UWB radar demonstrator with an array of four antennas. This project required the development of a new UWB antenna: the Valentine antenna. This antenna must be lighter and more compact in H-plane to allow the assembly of the array. This array must have a volume lower than 1 m . This antenna, which is composed of curved metallic strips, radiates ultrashort pulses in the frequency band 300 MHz -3 GHz with very low dispersion, a high gain and a low cross-polarization in the axial direction. The Valentine antenna must support 10 kV of peak voltage. This paper describes the Valentine antenna and its main radiation characteristics.
