A novel and simple ultrawideband (UWB) printed quasi-self-complementary antenna is presented. The proposed antenna, which is fed by a microstrip line, has been demonstrated to provide an ultrawide 10-dB impedance bandwidth with satisfactory radiation properties. It also features both physically and electrically small dimensions, 16 mm times 25 mm in a physical size and 0.24lambda in an electrical...
In this paper, a miniature printed quasi-self-complementary antenna fed by a microstrip line is proposed for UWB applications. A triangular slot is embedded on the ground plane to improve the impedance matching of the antenna. It has been illustrated that the optimal design of this type of antenna can yield an ultrawide impedance bandwidth with reasonable radiation properties.
In this paper, the miniaturization of a printed circular disc monopole antenna is investigated. It is shown that by halving the original antenna and adjusting the coplanar ground plane width, an even wider impedance bandwidth at the lower end can be obtained. Furthermore, a clear physical explanation is provided to illustrate the mechanism of this type of half circular disc antenna.
