Light weight rectenna fed by CPW with function of harmonic suppression
A novel circularly polarized rectenna with function of harmonic suppression is designed. The rectifier is directly integrated on the ground plane of the receiving antenna. The circularly polarized rectenna has the characteristics of light weight, compact size, low profile, and is easy to be conformed with the surface of aero-crafts. The rectenna works at 5.8 GHz and is fed by Coplanar Waveguide(CPW) coupling, which results in a broad working bandwidth. A Compact CPW Resonant Cell(CCRC) is directly loaded into the feeding to suppress the high order harmonics. The designed rectifier circuit adopts voltage doubling, and uses two chip capacitors for DC filtering and has a simple structure. The proposed rectenna has a compact structure and a 0.5 mm thick profile. Furthermore, the mass of the proposed design is only6.28 g and the optimum rectification efficiency is 63.84%. The test results are in good agreement with thesimulation results, which verifies the feasibility of the design.
