This paper addresses the design and the characterization of an innovative antenna so-called crossed dipoles array antenna which is integrated into a broadband compact rectenna operating in the K-band. A dedicated methodology design is presented in order to take into account the impact of the rectifier part of the rectenna on the antenna performances. Simulation and experimental results as well as...
An ultra-compact (2.5 cm2) rectenna design based on an innovative topology using a coplanar stripline connected to a crossed dipoles antenna array is reported here. Experimental results in the K-band show that a DC power up to 0.9 mW can be harvested on a 0.3 kΩ load by using the proposed compact rectenna for incident power density of 1413 µW/cm2. The targeted application for this rectenna is to power...
This paper addresses an ultra-compact (2.8 cm2) and wide bandwidth rectenna operating in the extended Ku-band. Experimental results demonstrate that the proposed rectenna can harvest a DC power ranging from 0.125 mW to 1.43 mW for frequencies between 14.5 GHz to 19.5 GHz and for resistive loads between 250 Ω and 4 kΩ. A maximum conversion efficiency of 55.3 % is obtained at 16.05 GHz for an incident...
