三阻带特性的超宽带天线研究与设计
Design of ultra-wideband antenna with three stop-band characteristics
摘要
Abstract
For solving the problem of band overlap between the ultra-wideband (UWB) communication and existing civil communication, a new type of coplanar waveguide (CPW) fed UWB antenna with three-stop-band characteristics is proposed in this paper. The essence of the prototype of proposed UWB antenna is a dipole antenna; therefore it has good omni-directional characteristics. Three-stop-band is obtained by embedding 3-step open circuit stubs and a step Impedance resonator-defected ground structure (SIR-DGS) in the ground plane, which can be controlled independently by respectively adjusting the length of the stub and the width of the DGS. The time domain characteristics of the antenna were simulated and analyzed through full-wave time domain simulations with the electromagnetic simulation software ( CST) . The actual tests further proved that the proposed antenna has a better omni-direction-al characteristics in the ultra wide bandwidth range of 3.1 ~10.6 GHz. The test results also indicate it has better stop band characteristics in the satellite communication frequency range of WLAN, Wimax, C-band and X-band.关键词
