共面波导馈电的蝶形缝隙天线及其散射特性研究
Study on Bow-Tie Slot Antenna Fed by CPW and Its Scattering Properties
摘要
Abstract
The bow-tie slot antenna fed by coplanar (CPW) is designed.CST 2011 is used to simulate the effect of antenna parameters (such as the length and width of the bow-tie slot and the thickness of the substrate) on the antenna's performance.The optimized antenna has an impedance bandwidth of 770 MHz,gain of 1.2 dB,and good radiation pattern characteristics.Moreover,the scattering property of the proposed antenna was simulated by CST 2011.The peak RCS of 10.67 dBsm appeares at the resonant frequency 2.56 GHz.Besides,RCS of the designed antenna loaded with resistance was calculated and analyzed.The results indicate that RCS of antenna can be reduced by loading an appropriate resistor.关键词
