I. Introduction
Recently, the electromagnetic harvesting of the spill-over losses of microwave antennas was identified as a realistic solution to power autonomous wireless sensors for health monitoring of the antenna panels of the broadcasting satellites [1]. This paper presents recent results in Ku band obtained from an innovative rectenna topology based on four printed cross dipoles antenna array and uses a low cost Schottky diode [2]. Rectenna using a cross dipole antenna was also reported in [1], [3] while a rectenna using a two cross dipoles array was reported in [4]. The rectenna topology and the design methodology are presented in Section II while Section III shows the experimental results obtained by using the manufactured rectenna.
