CPW fed Inverted U-Shape Microstrip Patch Antenna for WLAN/WiMAX Applications
A CoPlanar Waveguide (CPW) fed planar monopole antenna for WiMAX and WLAN applications is presented. The antenna, which occupies a small size, is simply composed of an inverted U-shaped radiating patch with E-shape slot. By carefully selecting the positions of this slot, reasonable bandwidth of the antenna can be obtained so that operating bands covering 2.4/5.2/5.8GHz WLAN bands and the 2.5/3.5/5.5GHz WiMAX bands. The measured results also demonstrate that the proposed antenna has appreciable bandwidth and is thus suitable to be integrated within the portable devices for WiMAX/WLAN applications.
