发明名称 Antenna for mobile communications device
摘要 A new category of mobile communications antenna is implemented in a single layer of conducting material. Wire-slot sections, including wire-tabs defining slots in the material, partially extend around the perimeter of at least one patch-tab section of the antenna. The perimeter of the at least one patch-tab section forms one edge of each slot, and the wire-tab of a wire-slot section forms a second edge of the slot. The wire-tabs of the wire-slot sections are separated from the patch-tab section by the slots and merge into the patch-tab section at a desired point. The length of each of the wire-slot sections may vary. A portion of each of a pair of the wire-tabs of the wire-slot sections functions as an input feed. The patch-tab section may be implemented as a single tab or as a plurality of tabs separated from one another by a slot. By varying the relative geometries of the patch-tab, wire-slots and tabs of the wire-slots, the electrical properties of the antenna, including the input impedance, can be adjusted.
