Abstract
A directional antenna is provided having an array of directional antenna elements arranged in at least one row. The directional antenna elements are activated in accordance with a predetermined pattern. The signal amplitudes on the receiving side are time-shifted to simulate a low-frequency signal for detection of deeper-lying anti-tank mines. Each directional antenna element has a pair of flat strips which lie close to each other at the base side and which proceed in parallel before diverging to a greater width toward the aperture side.
