A Novel Antenna for Transient Applications in the Frequency Band 300 MHz – 3 GHz: The Valentine Antenna

Abstract: 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… Show more

“…The aim of this project, pursued by the XLIM laboratory of Limoges University, was to design and produce a multi-source pulsed UWB radar system demonstrator based on the use of optoelectronic switches to extend the limits of pulsed UWB radars in terms of range, resolution and acquisition. The antennas developed in the project are based on the Vivaldi type profile, the Valentine antenna (Diot et al, 2007) being used for the construction of the transmission array and the Libellule antenna (Delmote et al, 2004) being used for the reception of the UWB radar signals formed. These two antennas (figure 4) are made according to the same principle but their geometry is different.…”

“…Because of its high gain and its capability to radiate short pulses without dispersion in the frequency band 300 MHz-2.5 GHz, the Valentine antenna [4,5] was chosen to be the radiating element of high-power UWB sources. A mechanical matching of the antenna, using the time-domain electromagnetic software CST Microwave Studio, was done to improve its dielectric strength.…”
