Irregular Circular Fractal Slot Antenna for Dual Wideband Applications
A compact CPW-fed fractal circle monopole antenna with dual wideband is presented for simultaneously satisfying Wireless Local Area Network (WLAN) for 2.4/5.2 and 5.8GHz application. The antenna consists of irregular shape circles based on the descartes circle theorem. The simulated -10dB bandwidth for return loss is from 2.04 to 3.35GHz and 4.96 to 5.9GHz, covering all the 2.4/5.2/5.8GHz WLAN bands obtained. It is observed that the gain of proposed antenna for 2.4GHz and 5.2GHz is 3.606dBi and 5.96dBi respectively. This antenna gives stable monopole-like radiation patterns.
