Description Shape control of parabolic cylindrical antennas and corresponding effect on radiation pattern, using piezoelectric actuators, is investigated. A narrow, 350-mm-long aperture,, parabolic cylindrical antenna of Lexan(R) material is chosen for analysis. Antenna deformation is analyzed using an experimentally validated piezoelectric shell finite element. Radiation pattern is calculated using physical optics. Significant steering and shaping are obtained by deforming the antenna using centrally placed actuators. Using the strategy of making the phase variation at aperture as linear as possible and adjusting the phase difference between the two halves of the antenna to be an integral multiple of 2pi, very good quality is achieved for the steered and shaped beams.
