Abstract:
1. An antenna comprising a lamina of conductive material, a slot loop being formed in the lamina, the antenna being operable in at least one resonant operational modes in which at least one portion of the slot loop is associated with an relatively high electromagnetic field and in which at least one other portion of the slot loop is associated with a relatively low or substantially zero electromagnetic field, wherein the lamina is folded on itself so that said at least one portion of the slot loop lies in a first plane and said at least one other portion of the slot loop lies in a second plane, the second plane being substantially parallel with the first plane, and wherein said antenna comprises a first and a second end region, and a central region located between the first and second end regions, each region comprising a respective portion of the lamina, and wherein said central region is located in said first plane and at least part of one or both of said end regions are located in said second plane, and wherein the central region includes at least two spaced apart portions of said slot loop and each end region includes a respective portion of said slot loop.
