Staggered pattern charge collector design and optimization

This paper outlines an innovative antenna configuration called a staggered pattern charge collector (SPCC) to increase microwave wireless energy harvested from an antenna at 5.8 GHz. The two-by-two staggered pattern charge collector (SPCC) uses a pair of two-element linear arrays to increase gain and effective aggregate “beamwidth” to capture more wireless energy than a single patch antenna. Also, a new array parameter called integrated power conversion gain (IPCG) is introduced as a metric to compare how effective antenna systems are at energy harvesting. Finally, the SPCC is optimized to maximize IPCG and the optimized, fabricated SPCC's DC voltage output data is measured.
