—A compact,ultra-wideband (UWB) monopole,antenna with four-band-notched characteristics is introduced in this paper. The proposed antenna can achieve four-band rejection at 3.4, 5.7, 8 and 11 GHz with desired bandwidths only using one novel structure called nested complementary,split-ring resonator (CSRR) which is etched inside the ground plane. This method used to obtain four-band- notched characteristics is firstly proposed in this paper. The antenna has a small dimension of 35 × 27 mm,. The VSWR and radiation patterns of the fabricated antenna are presented, which prove that the designed antenna is a good candidate for various UWB applications.
