“…The fractal geometry employed was based on a Koch curve that can have infinite iterations (Figs. 3a and b) [11]; however, in this paper just one iteration was used as a tradeoff between size and gain, since the first iteration provides the largest area reduction while for each additional iteration there is a reduction of the antenna gain [12]. Furthermore, from the second iteration, the Koch fractal geometrical characteristics become more complex and difficult to implement with simple PCB manufacturing techniques.…”

This work presents the design of a rectenna topology by using a compact microstrip patch antenna based on a fractal model and with the rectifier circuit integrated into the same physical structure. This configuration presents a very reduced circuit area, which makes the proposed rectenna circuit suitable for harvesting and wireless power transfer applications where the size is critical. The proposed compact rectenna, implemented on a low‐cost FR‐4 substrate, can harvest RF power from 2.45 GHz (ISM band) with a efficiency of ∼62% when the input power harvested by the rectenna is +2 dBm. The suggested rectenna has been manufactured and experimentally characterised, showing a good agreement with the expected simulated results.
