Abstract:
An antenna system, comprising:a substrate having first and second surfaces; and a complex pattern of electrically conductive material formed on said first surface, a location on said complex pattern defining a feedline feedpoint; a patch adjacent said second surface and spaced-apart from said complex pattern; said patch being formed from electrically conductive material and floating electrically; wherein said patch contributes a capacitive loading effect to said antenna system; wherein at least one characteristic of said antenna system is varied by at least one of orientation and size of said patch relative to said complex pattern; wherein said complex pattern contributes an inductive loading effect to said antenna system, and said antenna system exhibits multiple frequency resonant bands that are alterable by varying said complex pattern; wherein said complex pattern defines at least a second order fractal and includes a portion having at least a first motif and a first replication of said first motif and a second replication of said first motif such that a point chosen on a geometric figure represented by said first motif will result in a corresponding point on said first replication and on said second replication of said first motif; wherein there exists at least one non-straight line locus connecting each said point; and wherein a replication of said first motif is a change selected from a group consisting of (a) a rotation and change of scale of said first motif, (b) a linear displacement translation and a change of scale of said first motif, and (c) a rotation and a linear displacement translation and a change of scale of said first motif.
