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 design considerations relative to such antenna are presented with a focus on the trade-off between frequency bandwidth, antenna gain and the beamwidth.
