Abstract
In the disclosed wireless information consumer electronics apparatus, limitation of mounting position of antenna is small, and further limitation of place of installation of the apparatus is small. Further, when stacking up a plurality of information consumer electronics apparatuses such as set-top boxes, the limitation of communication area and shortening of communication distance are small in this apparatus. A metal casing is used as a resonance antenna. Current is supplied through mounting screws, grounding wires connected in direct current, or an excitation patch coupled electromagnetically. Diversity action in plural excitation modes is also possible. The antenna can be matched automatically by using varactor diode or ferrodielectric capacitor.
