A High-Power Microwave Source with High Peak-to-Average-Power Ratio Signal Output for WPT Applications

This paper proposes a high-power microwave source which is capable of outputting high peak-to-average-power ratio (PAPR) signal. The microwave source includes a dual-polarized dipole antenna array based on coherent stimulated emission for output power enhancement. Each dual-polarized antenna unit is loaded with two fast switching circuits at the two feeding ports, respectively, and biased by a DC voltage source. The dual-polarization characteristic can be realized by switching between two working modes.
