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.
