The design of reconfigurable multiband antenna for wireless applications such as UMTS, T-DMB, LTE, WiMAX, WLAN and WiBro bands applications is presented in this paper. The antenna is made up of four radiating elements which alternately play the role of active or parasitic element. In addition, we chose a reconfigurable antenna with a narrow bandwidth, in order to be able to shift in a radio frequency spectrum also to avoid band interference. This system is qualified to control the S11 by switching the four PIN diodes state while preserving the same structure.
