Abstract:
1. An apparatus comprising: a single antenna having a surface that radiates and receives electromagnetic waves, an entirety of an edge enclosing the surface shaped as a substantially non-periodic curve; said curve comprises a multiplicity of connected segments in which the segments are spatially arranged such that no two adjacent and connected segments form another longer straight segment; each segment is shorter than one tenth of at least one operating free-space wavelength of the single antenna; said curve is shaped so that the arrangement of the segments of the curve are not self-similar with respect to the entire curve; each pair of adjacent segments forms a bend such that said curve has a physical length larger than that of any straight line that can be fitted in the same area in which the segments of the curve are arranged, and so that the resulting antenna curve can be fitted inside the radian sphere of at least one operating frequency of the single antenna; the single antenna simultaneously receives electromagnetic waves of at least a first and a second operating wavelength, each of the first and second operating wavelengths being respectively within first and second non-overlapping frequency bands; and the first and second non-overlapping frequency bands corresponding respectively to first and second cellular telephone systems.
