Abstract: An optically scannable code antenna is provided. Encoded matrix codes are printed with electrically conductive material on a substrate. An antenna pattern is generated on the substrate from the electrically conductive material. Enclosed information in the matrix code and accessible via the antenna pattern is provided. At least a portion of the antenna pattern is also a portion of the matrix code. Signals are transmitted and received from the antenna pattern made up of a portion of the matrix code formed on the substrate by electrically conductive materials. Authentication and security measures using the matrix code and signal from the antenna pattern are also provided.

Abstract: A self-similar multiband reconfigurable antenna includes a planar antenna structure formed on a surface of a substrate, the antenna structure including symmetrically opposed self-similar geometry antenna arms defining a self-similar or Sierpinski gasket configuration for each arm of the antenna. MEMS type switches are provided for operatively connecting adjacent antenna patches on each arm of the antenna configuration, and a voltage source is provided for selectively actuating the switches. Selective actuation of the switches enables up to four different antenna configurations each having a different resonant frequency, and wherein each resonant frequency demonstrates a similar radiation pattern.
