ABSTRACT
A compact dual band uniplanar antenna suitable for 2.4 and 5.8 GHz (IEEE 802.11 b/g and 802.11a) WLAN application is presented. The 0.28λ0 × 0.32λ0 structure comprises of a modified slot line as the radiating element. The ground plane size of proposed antenna has negligible effect on the radiation characteristics which enables easy integration of the antenna with MMIC circuits. Design equations of the antenna are developed and validated on different substrates. The simulation and experimental results show that the proposed antenna exhibits good impedance match, moderate gain and stable radiation patterns in both the frequency bands.
