Use of Japanese Integrated Services Digital Broadcasting Terrestrial (ISDB-T) standard has resulted in broadcast of perpetually on, wireless digital TV signals over the air at wider bandwidths in UHF bands for smart phones & video-on-demand. This paper presents a unique energy harvesting prototype capable of scavenging wireless power from such broadcasts and well capable of powering on electronics operating at 3V from wireless TV signals for limited duty cycle at distance of 6.5km from source.
