An Asymmetric coplanar waveguide (CPW) Fed Miniaturized dual polarized (linear Polarized and Circularly Polarized) monopole Antenna Implemented. The Inverted-L Strip monopole antenna and the asymmetric ground plane for WLAN/Wi MAX applications are presented. Monopole antenna mainly icludes asymmetric ground plane which are fed with Coplanar Wave inverted L-shape strip and a slit embedded on the ground plane providing an orthogonal phase difference were designed to generate CP radiation. Inverted-L shape strip resonance and matching condition are examined by high-frequency structure simulator (HFSS) and the prototype is designed and measured. The measure simulated results shows that the monopole antenna impedance band-width with at −10 dB of 92.5 %( 3.36-6.66GHz) and a 3-dB axial-ratio bandwidth of 53.9 %( 5.4 -6.39 GHz) could be completed which could absolutely cover the WLAN (5.725 GHz - 5.85 GHz) band. Meanwhile, a linear polarization is also bought which could absolutely cover the WiMAX (3.3 GHz -3.7 GHz) bands. Orthogonal phase difference and average peak gain for lower band 1.9 dB and upper band 2.48 dB have been achieved, respectively.
