Abstract— This paper displays a new compact monopole antenna of dual band for WLAN/WiMAX applications. The designed antenna has very small size of 30×20 square millimeter. U-shaped patch printed on FR-4 substrate. Adding two parasitic elements on the ground plane which give a good performance at the two operating frequencies 2.4 GHz and 3.5 GHz. The return loss is
-21.71 dB at the operating frequency 2.4 GHz with bandwidth
237 MHz (2.276-2.513 GHz) and -24.24 dB at the operating frequency 3.5 GHz with bandwidth 505 MHz (3.328-3.834 GHz)
S11≤ -10 dB for the two bandwidths. The designed antenna has a low profile, low cost and simple feeding using microstrip line feed. Keywords—dual-band; monopole antenna; WiMAX; WLAN; resonant frequency; parasitic elements.

INTRODUCTION
Recently, wireless communication systems evolved dramatically. Future developments focused on the personal wireless communication devices to provide variety services and multi for example multimedia, speech and data transmission across different places in the world [1]. WLAN and WiMAX are very important techniques in the wireless communication systems. Because of the high speed connectivity between the different types of communication devices which providing multi services using different frequencies, WiMAX network needs wide bandwidth and many operating frequencies to keep up with the demands of users in the different places around the world. To provide this wide spectrum of the services the antennas of communication devices must have
