A frequency reconfigurable U-shaped antenna for dual-band WIMAX/WLAN systems
Abstract
A novel frequency reconfigurable antenna is proposed for WiMAX and WLAN applications. It has a simple structure and compact size of 0.44λg × 0.37λg. The proposed approach is based on utilizing of a double planar U-shaped antenna. Furthermore, to achieve a reconfigurable function, a PIN diode switch is introduced across the slot between the two U-shaped patches. By controlling the PIN diode, the antenna resonates at two modes of single and dual bands (WiMAX 3.2/3.5 GHz, and WLAN 5.2/5.8 GHz). The obtained gain ranges from 2.3 to 3.9 dBi within the whole operating bands. The simple configuration and low profile nature of the proposed antenna is suitable for Wireless communication systems.
