Abstract
An electronic device includes a main body, a baseboard, a ground portion, and a frequency selected ground (FSG) circuit. The baseboard is received in the main body and is spaced from the main body. The baseboard and the main body together forms a gap and the baseboard includes a feed point for feeding current to the main body. The ground portion is grounded and electrically connects the main body to the baseboard. The ground portion covers a portion of the gap to form a grounding area and a non-grounding area. One end of the FSG circuit is electrically connected to the main body and another end of the FSG circuit is grounded. The FSG circuit includes a plurality of inductors and/or capacitors. The FSG circuit has different impedances in response to the electronic device working at different frequency bands.
