This paper presents the design methodology for an antipodal Vivaldi antenna (AVA) catered to emit an impulse-like waveform. relevant for near-field imaging in impulse-radio ultra-wideband (IR-UWB) radar systems. The focus of the proposed design is to optimize the pulse response from a time-domain perspective. We have examined the radiator parameters that influence the evaluation factor. https://lecoureures.shop/product-category/course-a-pied-femme-vetements-chandail/
