Compact rectenna for space application [PDF]
2014 IEEE MTT-S International Microwave Symposium (IMS2014), 2014 This paper addresses an ultra-compact (2.8 cm 2 ) and wide bandwidth rectenna operating in the extended Ku-band. Experimental results demonstrate that the proposed rectenna can harvest a DC power ranging from 0.125 mW to 1.43 mW for frequencies between 14.5 GHz to 19.5 GHz and for resistive loads between 250 Ω and 4 kΩ.
