Abstract: A dual-band differential fractal slot antenna with enhanced gain for RF energy harvesting applications has been proposed in this paper. The antenna is designed to operate in frequency bands of UMTS (2.1 GHz), and WiMAX (3.3-4.1 GHz). The reflector directs the radiation in the forward direction, which results in an improvement in the gain, impedance matching, and reflection coefficient bandwidth of the two bands. The proposed antenna is designed, fabricated, and the results of the simulation and measurement are compared. The theoretical analysis of the proposed antenna is also carried out. The maximum gain of the antenna with the reflector at 2.18 GHz and 3.72 GHz frequency is more than 6 dBi. The antenna radiation efficiency of 62% and 84% are obtained for the UMTS and the WiMAX bands of operation, respectively. © 2020 Indian Radio Science Society.
