A novel small ultra-wideband antenna (UWB) design using an individual split-ring resonator and coupled microstrip line structure is proposed. The radiation property of the antenna is numerically simulated and experimentally measured. The absolute frequency band, where S11 is less than 10 dB, is found to be across the entire UWB spectrum from 3.6 to 14.6 GHz. The gain at every frequency for the antenna...
