A new low power and low cost technique is proposed for designing agile antennas by using a reconfigurable radial waveguide excited by a central probe and feeding multiple radiating elements. The power distribution of the radiating elements is controlled by a cylindrical Electromagnetic Band Gap structure with PIN diodes allowing azimuth beam steering and multiple-beams. The proposed technique permits any polarization and it can be used for beam steering in both azimuth and elevation by adding control circuits in the radiating elements. Numerical and experimental results are presented for validation.
