| 1. A reconfigurable antenna comprising:
a substrate;
a metallic antenna patch structure formed on a surface of said substrate, said antenna structure including symmetrically opposed
fractal geometry antenna patches defining a reconfigurable self-similar configuration;
switches operatively connecting adjacent antenna patches on each arm of the self-similar configuration;
a DC voltage source for selectively actuating said switches; and
a plurality of bias lines electrically coupled to the DC voltage source and at least one of the switches, the plurality of
bias lines comprising bias line portions which are parallel to each other and to an adjacent antenna patch edge to constructively
interfere with the antenna's radiation pattern during operation.
