Double L - slot microstrip patch antenna array for WiMAX and WLAN

A Coplanar Waveguide fed double L slot antenna array is proposed for multi-band operation satisfying WLAN and WiMAX. The proposed array antenna comprising two rectangular planar patch elements each embedded with two L shaped slots. For the proposed antenna, the -10 dB return loss is achieved and it reach about -35 dB which covers some of the bandwidth specification of WLAN and WiMAX standards. Due the advantages such a slow cost, small size, low weight and capability to integrate in applications such as mobile phones and laptops the microstrip antennas are used. The parametric study is performed to understand the characteristics of the proposed antenna. It shows that the features of the small antenna structure, good radiation characteristics are promising for multi input multi output operation.
