An ultra-compact (2.5 cm 2) 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/cm 2. The targeted application for this rectenna is to power autonomous wireless sensors for satellite health monitoring.
