A wireless communication device includes a main body, a cover, a base board, an elastic member, and an antenna module. The cover is attached to the main body. The base board includes a feeding point and a grounding point. The elastic member is connected to one of the feeding point and the grounding point. The antenna module includes a first antenna and a second antenna connected to the other feeding point and the grounding point of the base board. The base board, the elastic and the antenna module are mounted in the cover. The elastic member selectively causes the first antenna or the second antenna to contact to the one of the feeding points and the grounding point of the base board when in an open or closed state.

Wireless communication device

An electronic device includes a multi-layer circuit board, a main antenna, and an electronic element. The multi-layer circuit board includes an outer layer, a ground layer, and a plurality of vias defined therein electrically connected the outer layer and the ground layer. The main antenna is mounted on the outer layer and electrically connected to the ground layer by the vias. The electronic element is mounted on the outer layer, soldered on the main antenna, and electrically connected to the ground layer by the main antenna.

Electronic device having antenna

An antenna module includes an antenna, a substrate defining a plurality of notches, and a plurality of filling blocks. The antenna is attached to the substrate. The filling blocks have a permittivity higher than the substrate and are received in a portion of the notches covered by the antenna to raise the permittivity of the substrate.
