Abstract: A built-in antenna device for an electronic device for communication is provided. The antenna device includes a substrate, an antenna radiator, and a transmission line. The substrate includes a grounding region and a non-grounding region. The antenna radiator is disposed in the non-grounding region of the substrate and fed from a feeding portion provided to the substrate. The transmission line branches from the antenna radiator and is disposed in vicinity of the grounding region to have a predetermined length and a predetermined width. The antenna device controls reactance by coupling the transmission line with the grounding region to allow the antenna radiator to operate in at least one desired band.
