Abstract
An antenna apparatus is proposed, which can be operated outside in the vicinity around the antenna apparatus despite a shielding effect of an electrically conducting frame or electrically conducting housing. In the process, the electrically conducting frame or electrically conducting housing encloses a housing volume inside the housing, within said volume an electrically conducting connection being produced from a first to a second location of the electrically conducting frame or the electrically conducting housing. The first and the second locations are selected such that a radio resonance chamber is separated by a parallel radio resonance at a working frequency of the electronic device inside the enclosed housing volume by means of the electrically conducting connection.
