平面印刷单极子天线频带抑制技术的应用
Applied research on band notched techniques in planar printed monopole antennas
摘要
Abstract
The Coplanar Waveguide ( CPW) fed circular monopole antenna is improved to suppress the interference among different wireless systems. An ultra wideband ( UWB) antenna with dual band notched characteristics and a tri-band antenna for WLAN/WiMAX applications are, respectively, proposed in this paper. The UWB antenna with the measured band rejection of 3. 29 - 4 GHz and 5.29-6 GHz is designed by loading two pieces of polygonal slotline at the bottom of the circular patch. Its notched frequency bands cover WLAN and WiMAX systems. In the design of the tri-band antenna, the frequency band of the antenna is controlled and notched by loading the elements of slotline, resonant stub and radial slot on the antenna. This tri-band antenna renders the measured frequency bands of 2. 25 - 2. 8 GHz, 3. 3 - 3. 8 GHz and 5. 1 ~ 5. 9 GHz, which cover the application bands of WLAN/WiMAX, and has good band rejected characteristics in the remaining frequency band. Both the proposed antennas are of adjustable frequency band, and are suitable for suppressing the interference among wireless systems in the complex circumstance.关键词
