A novel switched-beam planar fractal antenna is presented to demonstrate the capability of beam steering by controlling MEMS switches on/off. Simulated and measured results show that two switchable directional patterns, covering ranges from 0° to 60° and from −60° to 0° in the y-z plane, can be obtained around 8.8 GHz and the |S 11| are lower than −10 dB.
