Design of compact rectifying circuit with harmonic rejection filter for RF energy harvesting at 900 MHz
A compact rectifying circuit with harmonic rejection filter is designed and fabricated on a low cost FR-4 substrate for operation in the GSM/CDMA 900 band. The dimension for the complete rectifier is 80×45×1.6 mm3, which can be considered to be quite compact at 900 MHz. The rectifying circuit consists of the matching network, a diode, and a DC pass filter for rejection of higher order harmonics. The DC pass filter is based on three fan shaped radial stubs in order to block higher order harmonics, and the overall analysis shows an improvement of 19% in efficiency as compared to the circuit without filter. The measured results show the maximum output voltage of 3.4 Volt at 3000 Ω load. The design of rectifying circuit is simple and easy which can be easily integrated for the application of microwave power transmission circuit.
