Bandwidth Enhancement of a Wide Slot UWB Antenna with a Notch Band Characteristic
A Coplanar waveguide (CPW) fed ultra-wideband (UWB) antenna with a notch band characteristic is presented for 2.4GHz and UWB applications. The proposed antenna consists of a wide slot, square ring, and a CPW fed structure. The impedance bandwidth is broadened by embedding two inverted L-shaped slots in the CPW ground and the notch band is achieved by etching a rectangle slot in the CPW ground. The notched band can be controlled by adjusting the length of the rectangle slot and the two inverted L-shaped slots. Experimental and numerical results show that the proposed antenna with compact size of 28×2lmm2,has an impedance bandwidth range from 2.38GHz to 12.0GHz for voltage standing-wave ratio (VSWR) less than 2, expect the notch band frequency 5.0GHz-6.0GHz for HIPERLAN/2, IEEE 802.11a (5.1 GHz- 5.9GHz) and C-band (4.4GHz-5GHz) for satellite and military applications.
