Abstract (en)
[origin: EP0851530A2] A wireless terminal comprising a housing (102) that comprises an enclosed conductive element (200) that contains a radio has one or more openings (120) is used to provide both electromagnetic shielding and an integrated antenna. The openings (120) are excited to resonate, thereby forming a slot antenna for the radio Multiple openings can be used to provide antenna diversity. <IMAGE>
