【 摘 要 】

This paper reports a 2.45 GHz circularly polarized rectenna whose rectifying circuit includes two Schottky diodes. The rectenna consists of a truncated square patch antenna and a rectifying circuit with stubs which can block harmonic signals up to the third order. The proposed rectenna provides a good electromagnetic energy harvesting technique and it is well suitable for wireless sensor applications because no input low pass filter and no via-hole connections are required, resulting in more simple structure. The dual-diode rectenna can provide at least twice the dc output voltage than the traditional rectenna with only a single diode, which has the same layout dimension as the single-diode rectenna.
