Abstract:
An antenna system comprising:a first fractal antenna including a first element having a portion that includes:at least a first motif selected from a family consisting of (i) Koch, (ii) Minkowski, (iii) Cantor, (iv) torn square, (v) Mandelbrot. (vi) Caley tree, (vii) monkey's swing, (viii) Sierpinski gasket, and (ix) Julia;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;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, and wherein said first fractal antenna is characterized in space by at least one resonant frequency and by a bandwidth; anda conductive element, spaced-apart from said first fractal antenna by a distance .DELTA. chosen to vary at least one characteristic of said antenna system, at a desired frequency c/.lambda., where c is velocity of light, selected from a group consisting of (i) said resonant frequency, and (ii) said bandwidth.
