to design an antenna which is capable of transmitting and receiving electromagnetic waves operating at 433MHz. Our aim is to maximize the gain of the antenna and achieve impedance matching between load impedance and transmission line’s impedance. Among a wide range of different antennas‚ our group decide to build up a Yagi Uda antenna to fulfill this assignment for two main reasons. Firstly‚ the gain that Yagi Uda antenna provides is very high. Hence for transmission‚ Yagi Uda antenna makes sure all

Antenna Characterization for Wireless Power-Transmission System Using Near-Field Coupling Wireless power transmission is the transmission of electrical energy from a power source to an electrical load without man-made conductors. Wireless transmission is useful in cases where interconnecting wires are inconvenient‚ hazardous‚ or impossible. So a study was made on the investigation of wireless power transmission by near-field coupling from the view
