Dual Band CPW Fractal Geometry Shaped of Pentagonal Island for WLAN and WiMAX

A dual-band CPW fractal geometry shaped of a pentagonal island antenna for WiMAX and WLAN applications is presented in this paper. The work began with Antenna A as the initiator step, while Antenna B was the pentagonal island-shaped antenna with CPW. Then it goes to Antenna C with the fractal geometry shaped of a pentagonal island antenna with the CPW technique. According to the research results, Antenna C has a sensitivity of - 25.20 dB at 3.5 GHz and - 21.14 dB at 5.8 GHz, which is suitable for WiMAX and WLAN operation.
