Abstract :
Theoretical and experimental studies of the influence of mutual arrangement of wideband tapered slot antennas (TSA) in the array are presented. Major attention is paid to reducing antenna coupling. The modeling was done using a transient solver realized in the CST Microwave Studio software. It was found that a parallel displacement of the antennas in the array when the distance between antenna planes is kept, allows to suppress unwanted lateral coupling that leads in turn to reduction of clutter. The antenna array consisting of the TSA had been fabricated and tested in a test site for the detection of low-contrasted objects like anti-personnel mine.
