Abstract :
Artificial magnetic materials based on fractal Hilbert curves are used as a substrate to increase effective permeability, thus leading to antenna size miniaturisation. A miniaturised patch antenna with miniaturisation factor of 5.3, and impedance bandwidth of 2.11% is designed, numerically tested, fabricated, and measured.
