摘要：
In this letter, a novel printed frequency-reconfigurable microstrip square slot antenna for switchable Bluetooth, WiMAX, and WLAN applications is presented. The proposed antenna has a small size of 20 x 20 mm(2) in order to be able to cover lower frequencies; as for Bluetooth applications, miniaturization techniques such as modification of the ground plane and inserting an adjustable backplane cross-shaped sleeve have been employed. Moreover, by implementation of p-i-n diodes within the antenna structure, switchable frequency responses are achieved. The presented antenna has a small size while providing suitable switchable radiations at 2.3-2.51 GHz (BW = 8.7%) Bluetooth, 3.35-3.75 GHz (BW = 11.2%) WiMAX, and 4.95-5.53 GHz (BW = 11%) WLAN.
