Summary:
A compact tri-band planar monopole antenna is proposed in this paper that employs reactive loading and a defected ground plane structure. This proposed antenna operates in two modes. The first resonance exhibits a dipolar mode over the lower WiFi band of 2.40? 2.485 GHz and the upper WiFi band of 5.15 - 5.70 GHz. The second resonance has a monopolar mode over the WiMAX band at 3.30?3.70 GHz. Full-wave analysis shows that the currents of these two modes are orthogonal to each other, resulting in orthogonal radiation patterns in their far field. The defected ground, formed by appropriately cutting a spiral-shaped slot out of one of the CPW (Coplanar Waveguide) ground planes, leads to the second resonance.
