## Abstract A novel frequencyβadjustable ultra wideband antenna with coplanar waveguideβfed is proposed and the design formula is presented. The optimized antenna presents 6.7:1 ratio bandwidth and 148% impedance bandwidth for the return loss less than β10 dB. The bandwidth can be changed through a
