Paper Abstract

Recently, it has been demonstrated that aperture antennas can have their performance improved by utilizing PVDF as a shape controlling actuator. Since PVDF is a polymer with limited control authority, these antennas can only be employed in space based applications. This study examines more robust antenna structures devised of a thick metalized substrate with surface bonded piezoceramic (PZT) actuators. In this work, PZT-actuated adaptive antennas of cylindrical- cut shape are studied. First, the PZT-actuated antenna surface is modeled based on the classical curved beam theory and Newton's method. Second the Voltage vs. Deflection relationship is experimentally verified. Third, the resulting far field radiation pattern is simulated on computer.
