A frequency switchable monopole antenna fed by micro strip line feeding for Bluetooth, WiMAX and WLAN applications is proposed in this article.
The designed antenna dimensions are 37.0x25.5x0.8mm3. The proposed antenna comprises of 4 hemispherical rings, 1 orbicular ring, 3 rectangles and 1 arc shape ground plane.
The proposed antenna is designed and simulated by finite element method-based tool HFSS.
The proposed antenna achieves frequency reconfiguration and the antenna is made switch to various frequencies by using 3 PIN diodes.
The antenna designed covers at 3 bands centred at 2.39GHz, 3.38GHz and 5.38GHz. The proposed antenna achieves a high efficiency of 95% and impedance bandwidth of 48%. The design exhibits compact size, good performance and low profile suitable to wireless system applications.
