Description

technical field [0001] The present invention relates to the field of wireless energy transmission, and more specifically, relates to a microstrip rectenna based on a WIFI frequency band. Background technique [0002] Microwave Power Transmission (MPT: Microwave Power Transmission) refers to a new transmission method to achieve energy transmission in vacuum or atmosphere without any other transmission lines or waveguides. At the end of the 19th century, the American scientist Nikola Tesla first proposed the concept of MPT. In the 1960s, MPT technology was first used in high-power applications, including power generation in space, power transmission from the ground to aircraft such as satellites and aircraft, military directed energy weapons, and interstellar exploration. However, because the overall conversion efficiency of the MPT system is not high, and the high-power microwave electromagnetic field has a great impact on the ecological environment and biological safety, th...
