A Dual-Band and Flexible CPW-Fed Antenna for RF Energy Harvesting Applications

Résumé

This paper addresses a new design of a dual-band monopole antenna on a Polyimide flexible substrate fed by coplanar waveguide technique. The final purpose of the antenna will aim to be used with a rectifier circuit as part of a rectenna for RF energy harvesting in the ISM Band. Consequently, the layout of the rectifier was considered in the simulation step. The proposed topology of this CPW-feed dual band antenna is based on a modified monopole antenna combined with a rectangular loop ring and has dimensions of 38 mm × 30 mm × 0.125 mm. Interesting performances are achieved in terms of radiation patterns. On the first band at 2.42 GHz, the maximum antenna gain is about +2.29 dBi with a quite omnidirectional pattern but in the second band, the antenna is more directive with a higher gain +3.97 dBi at 5.84 GHz.
