Abstract :
Fractal antennas are well known for their multiband characteristics. A new approach to multi-frequency re-configurable antennas using RF-MEMS switches is presented. Fractal antenna elements can be connected together using RF-MEMS switches in order to achieve a larger number of resonances. The RF-MEMS switches permit a controlled connectivity of sections of the antenna´s conductive parts. This conductive coupling between the triangular elements of a Sierpinski structure provides clear multiple frequency operation with a single fractal antenna. The analysis and design principles are discussed and presented.
