Abstract :
This paper introduces the theory of N-by-N staggered pattern charge collectors (SPCC) and a methodology to design and optimize SPCCs for maximum energy harvesting efficiency. The SPCC uses multiple sub-arrays to form an aggregate gain pattern for harvesting RF wireless energy more efficiently than a single antenna or a collection of antennas occupying a similar footprint when the transmitter location is unknown.
