Abstract
A printed circuit board having a built-in antenna may include a first unit substrate, in which a ground and a first radiator are formed; a second unit substrate, which is stacked over the first unit substrate, and in which a second radiator having a frequency band different from a frequency band of the first radiator is formed; a pair of striplines, formed in the first unit substrate and connected with the ground; a first via, which connects the first radiator with the second radiator; a pair of second vias, each of which has one end connected with the pair of strip lines respectively; and a connection pattern, which connects the other ends of the pair of second vias to each other. The printed circuit board having a built-in antenna can utilize multiple frequency bands, and can be implemented in a compact size, to be applicable in compact communication devices.
