Abstract :
We propose a novel design of a frequency reconfigurable antenna. The electrical length and return loss of the antenna are reconfigured by RF-MEMS switches. The area of the antenna element is 15 × 50 mm2. The measured total efficiency of the antenna is higher than -3 dB at almost all frequencies between 0.78 GHz and 5.85 GHz. This antenna is suitable for future mobile terminals, which include many radio systems.
