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.
