摘　　要：提出了一种结构新颖的双环天线,该天线具有结构简单、宽带、宽波束、圆极化等诸多优点,通过实验测试方法验证了设计的有效性。同时提出了通过附加反射板的方法提高了该天线的低仰角增益,并对天线的输入阻抗和圆极化轴比有一定的改善作用。Antenna with broad bandwidth , wide beam and circular polarization performance are needed in spaceborne, airborne and terrestrial application. A novel double-ring antenna is presented. The structure of this antenna is also very simple. The measurement of radiation characteristics is in good agreement with simulation results. The gain of low elevation angle can be improved by adding a metallic reflector, and the input impedance and the axis ratio can also be improved.
