Abstract: The present disclosure relates to an intelligent wireless power transmitter. The intelligent wireless power transmitter includes an array antenna module configured to transmit microwaves, and a local controller configured to control a phase of the array antenna module so that the microwaves radiated through the array antenna module is transmitted to a target wireless power receiver.

Abstract: The described technology relates to a wireless power transmitting antenna and a wireless power transmitter having the same for wirelessly supplying power to a wireless sensor module implanted inside a human body to monitor a bio-signal, a wireless sensor node in a wireless sensor network which is difficult for a human to access, a personal handheld terminal such as a smartphone or the like, indoor and outdoor wireless lightings, etc. The wireless power transmitting antenna includes a ground layer, a dielectric layer disposed to be spaced a predetermined distance from the ground layer to form an air layer disposed therebetween, and a radiation patch portion formed on the dielectric layer and configured to radiate electromagnetic waves, and thereby loss of the electromagnetic waves is reduced by forming low permittivity and the gain of the radiation patch portion is increased without additionally configuring a separate dielectric layer.

Abstract: The present invention has been made in an effort to overcome the disadvantage that a user has to consciously adjust the positions of a wireless power transmitter and a wireless power receiver. The transmitting antenna for wireless power charging, which wirelessly transmits power to charge a device, includes a first antenna coil section for producing a magnetic field in a first direction, and a second antenna coil section for producing a magnetic field in a second direction. Accordingly, the three-dimensional transmitting antenna can minimize decreases in efficiency caused by the position and direction of the receiver and maximize reception efficiency at a particular point or within a particular range.
