Abstract :
The beamforming action of three planar frequency-selective surfaces (FSSs) placed in front of a waveguide aperture in a ground plane is demonstrated experimentally, together with the application to printed antennas. A simple ray theory illustrates the leaky-wave action for one FSS in position and the advantages and disadvantages of this beamforming technique are noted.
