S. Ladan and K.Wu have designed a self-biased, highly efficient microwave rectifier circuit which operates in the K-band frequency region. By designing a self-biased rectifier, they are reducing the power consumed by the circuit and especially for Wireless power transfer, reducing the power is one of the highest priorities. The circuitry also involves no usage of lumped elements for matching purpose before the rectification of the AC signal which also adds to low loss. Since, the operating frequency is high, lower wavelengths, the form factor of the system will be very low. We could utilize the self-biasing idea on to our WPT system at C-band frequency. This also gives us motivation to work in higher frequency bands for WPT which will reduce the form factor greatly.
