Abstract :
In this paper, the interdigital structure is applied to the design of a miniaturized planar log-periodic antenna which is used in a TV broadcast wireless energy harvesting system. The lateral size of the printed antenna can be reduced approximately 35% while the overall performance characteristics is improved slightly. The simulated gain reaches 7.27dB at 515MHz and the measured -10-dB bandwidth is from 500MHz to 600MHz, which is sufficient for the television band in Suzhou, China. The energy harvesting system equipped with the proposed antenna is tested, and the measured output voltage is 2.2 V.
