Abstract

The paper presents a dual band U shaped slot antenna using an asymmetric coplanar waveguide feeding technique (CPW) from right side of slot. The impedance bandwidth of proposed antenna varies from (1.7 GHz - 2.8 GHz) and (3.5 GHz - 5.7 GHz), which is 49% in lower band and 48% in upper band that covers applications in WLAN (2.4 GHz, 5.15 GHz), Bluetooth (2.4 GHz), and other mobile applications. VSWR<=2 is obtained over both frequency ranges. An additional upper band is obtained using U-slot whereas only lower band (1.7 GHz - 2.6 GHz) was obtained using square slot. All the results are simulated and analyzed successfully.
