Abstract:
A Printed Circuit Board (PCB) and an embedded antenna for a mobile communication terminal having double feed points using the same are provided. The embedded antenna includes a PCB having an emission carrier. The emission carrier includes first and second feed points connected to a feed wiring layer of the PCB, as well as an emission pattern to which the feed points are connected. The feed wiring layer supplies a current to one of the feed points, and has a connection wiring for supplying a current from the feed point to the other feed point. Through overlapping between a first resonance spot created by the first feed point, and a second resonance spot, which branches off from the first feed point and connects to the PCB, the frequency bandwidth can be expanded, which accommodates any frequency shift minimizes deterioration resulting from the influence of human bodies, and maintains stable antenna characteristics.
