Abstract
AbstractIn this letter, a compact reconfigurable multiband antenna is presented. The antenna can operate in seven different modes categorized into three types, single band, dual band and triple band. The antenna is optimized to work in any band that encompasses the three standards that are, WiFi (2.4 GHz), WiMax (3.5 GHz), and WLAN (5.2 GHz). The locations of the slots as well as the size of the antenna have been optimized in order to reduce as much as possible the total area of the final prototype. For the reconfiguration four switches are integrated on the three slots to switch from one mode of operation to another. As the first validation approach, the two states “on/off” of the switch are modeled by the presence/absence of a perfect conductor (PEC). The results of measurements and simulations are presented and compared and a good agreement is established. The proposed antenna is a good candidate for multiservice and cognitive radio applications.
