Summary:
In recent years, wireless power transfer has gained a great attention in many of wireless sensor applications [1-4]. As a key component in a wireless power transmission system, a rectenna undertakes the task to convert the received RF power into dc power which can then be consumed by other subsystem [5-9]. From the literatures [5-10], a rectenna design is a system design, which commonly includes antenna, filter, matching network, and part of rectifying circuit. For accuracy, most of the design work need system Circuit/EM Co-simulation to guarantee the required performance [3-10], and these processes lead to increase the design cycle time a lot. On the other side, compact size, low cost, and high integration have been required in modern wireless communication system. Several compact and low cost and uniplanar rectenna systems have been reported with high conversion efficiency [5, 7]. However, the operations of the reported rectennas need a tuneable reflecting plate which may disobey the tendency of easily and highly integration in modern wireless communication system. In this paper, a novel and highly integrated uniplanar rectenna system is proposed. The proposed rectenna works in the direction along the substrate, and then, no conventional reflecting plate is needed. A 2.45 GHz rectenna system is designed and measured to guarantee their microwave performances.
