  • Patent number: 7990320
    Abstract: One aspect of the invention relates to an antenna for a wireless device having spring contact elements based on strips (301, 302; 403; 503, 504; 602, 603; 612, 613; 622, 623; 632; 642; 652, 653; 682; 703, 704; 753, 754; 756; 802, 803; 1412, 1413; 1422, 1423) that, before bending, are housed in at least one gap (303, 601, 681, 804, 1411, 1421) in a main body (300, 402, 502, 600, 700, 750, 800 1400) of the antenna. The invention provides for a reduced stamping area overhead while allowing the spring contacts embodied by the strips to be placed close to the perimeter of the smallest possible rectangle that can house the main body.
