We describe here an optimization procedure to shape the radiation pattern of planar two-dimensional (2-D) leaky-wave antennas. The structures under investigation are superstrate configurations made by partially reflecting screens (impedances sheets) over a ground plane and excited by open-ended waveguides. The antenna configuration providing...

wideband antenna array is developed for the land-mine detection in the desert with an on-board radar. The final array is very large and contains 128 Vivaldi antennas. The array is split into 16 sub-arrays of 8 elements. Each Vivaldi antenna is driven independently by electronic switches for SAR imaging purpose. In a first step, a sub-array of 8...
