An UWB impulse radio programmable transmitter array is presented, usable for electromagnetic beamforming. The linear antenna array may be programmed for focal beamforming using seven impulse radio transmitters. Two different spatial configurations are evaluated for use as beam scanning electronics of an electromagnetic camera. A novel high-precision, programmable delay element is explored for accurate beam control. Measured results shows that the scan line of the beamformer can be steered with sufficient resolution facilitating an electromagnetic CMOS camera.
