Wireless Power Transmission for Solar Power Satellite ( SPS ) ( Second Draft
1. Theoretical Background It is known that electromagnetic energy also associated with the propagation of the electromagnetic waves. We can use theoretically all electromagnetic waves for a wireless power transmission (WPT). The difference between the WPT and communication systems is only efficiency. The Maxwell's Equations indicate that the electromagnetic field and its power diffuse to all di...
متن کاملRectennas for microwave power transmission
Microwave power transmission (MPT) has had a long history before the more recent movement toward wireless power transmission (WPT). MPT can be applied not only to beam-type point-to-point WPT but also to an energy harvesting system fed from distributed or broadcasting radio waves. The key technology is the use of a rectenna, or rectifying antenna, to convert a microwave signal to a DC signal wi...
متن کاملA 5.8 GHz Rectenna Design for Microwave Power Transmission
In this era of the Internet of Things, we designed a rectenna working at 5.8 GHz in order to solve the finite things about battery-powered wireless sensor. First, an E-shape embedded microstrip feed antenna by HFSS software has been designed, then a technique called “offset correction” to balance the deviation between theory and simulation was proposed. It effectively spanned the gap between si...
متن کاملOptimal Array Beamforming for Microwave Power Transmission in Complex Environment
Wireless Power Transfer(WPT) is a popular research field in recent years and can be categorized into three approaches: inductive coupling, laser beaming and microwave power transmission(MPT). MPT system operates at the microwave frequency and transfer the energy over more than a few wavelengths. It has its unique advantages of supplying power to nonaccessible and mobile receivers. The overall e...
متن کاملProgress in Low-power Digital Microwave Radiometer Technologies
Three component technologies were combined into a digital correlation microwave radiometer. The radiometer comprises a dual-channel X-band superheterodyne receiver, lowpower high-speed cross-correlator (HSCC), three-level ADCs, and a correlated noise source (CNS). The HSCC dissipates 10 mW and operates at 500 MHz clock speed. The ADCs are implemented using ECL components and dissipate more powe...
