Summary: | Efficient feeding geometries for rectenna design at 2.45 GHz are described. The proposed rectenna consists of two layers low cost FR-4 substrates in which circular polarisation and harmonic rejection properties are embedded. A voltage doubler rectifier with open stub matching network and the radial stub is designed at the bottom substrate to transform the ac signals to a dc voltage. A right triangular slot is designed in the ground plane to suppress second and third harmonics which improves the rectenna conversion efficiency to 75.043% at an input power of 20 dBm. The proposed rectenna design has the advantages of providing circular polarisation and harmonic rejection with a compact size and low cost which makes it a good candidate for microwave power transmission applications. |
