Abstract :
Based on radiation principle of CPW (coplanar waveguide) antenna and series-feed theory, a novel series-feed CPW antenna of coplanar waveguide structure is presented in this paper. The bandwidth is about 260 MHz (VSWR¿2) with a range from 10.54 GHz to 10.8 GHz. The side-lobe level is less than -13 dB. The simulated and experimental results demonstrate stable radiation pattern and wide impedance width.
