【摘要】 研究了采用阻抗加载技术实现天线电隐形的方法。对于两副天线共同构成的系统,可通过在非工作状态的天线端口上加载合适的阻抗,将其表面感应电流近似归零,从而实现非工作状态天线对工作状态天线的电隐形状态。此时,非工作状态天线对工作状态天线辐射方向图的影响最小化。通过一对偶极子天线和一对微带天线的仿真分析,验证了该方法的有效性。更多还原

【Abstract】 The approach to achieve the electrically invisible state of an antenna by impedance loading technique is investigated. For the system consisting of a pair of antennas,the induced surface current of the non-working antenna can approximately become zero by loading impedance at the port of antenna. Then,the electrically invisible state of the non-working antenna is obtained. By this method,the interference of non-working antenna to the radiated pattern of working antenna can be removed. Though the simulation and analysis of a pair of dipoles and a pair of microstrip antennas,the effectiveness of the method is proved.更多还原
