Paper Abstract

The previous experimental results showed that 230 volts of output was obtained from a 6 x 6 array at a far-field exposure (1.8 meters away) with an x-band input power of 20 watts. This result showed a feasibility of using a microwave to power feed and control smart actuators. Based on the previous research reported, we have achieved 500 V output level for practical applications. However, the rectenna has rigid structures that may give a limitation of flexibility of the smart actuators’ system. In order to apply this concept into real applications, the rectennas have to be flexible, so that it could be patched on smart actuators. In this paper, a design concept of various flexible rectennas and their performances in terms of design parameters such as geometry of rectenna will be discussed as well as integration for a system. The performance of flexible designed rectennas as a preliminary experiment will be presented in terms of the input power, output power of the rectennas, various shapes of rectennas in an array for difference applications, and their efficiencies.
