Abstract :
A novel method for beam steering with an active ultra-wideband antenna array is presented for impulse-radio ultra-wideband. The antenna array consists of four planar Vivaldi antennas in a collinear arrangement with an impulse generator circuit mounted chip-on-board on each antenna element. The beam steering is done by shifting the phase of the control signals triggering the impulse generators. In the array arrangement a measured beamwidth of 16° is achieved for an antenna spacing of 4°cm compared to 80° for a single Vivaldi antenna. Beam steering is experimentally demonstrated for a steering angle of 30°.
