Fabrication method and apparatus for antenna structures in wireless communications devices |
摘要 |
There is disclosed a meanderline loaded antenna formed by applying a conductive ink or other conductive material to a flexible substrate. The substrate is then shaped by removing regions and folding other regions along perforated or scored lines to fit the antenna within the available space of a wireless device. In lieu of folding regions of a planar substrate to form a three-dimensional structure, the substrate can be vacuum formed over a mandrel after the antenna elements have been formed thereon. The antenna can also be formed by printing on existing enclosure surfaces of a wireless device or on the surfaces of components within the device. Thus the advantages offered by a meanderline antenna where the effective electrical length is greater than the actual physical length are achieved in conjunction with a space-saving physical structure for the antenna.
