本文提出了一种双圆极化锥形波束微带天线。该天线在二阶模式激励下产生锥形辐射方向图，通过混合耦合器馈电实现双CP工作，在不同金属反射面尺寸下具有稳定的性能。测试结果与仿真结果一致，获得了良好的双CP锥形方向图，验证了所提设计的有效性。所有这些特点使得所提出的天线非常适合车载卫星通信应用。
A dual-circularly polarized (CP) microstrip antenna with conical-beam radiation is presented in this letter. The antenna is excited at the second-order mode to generate the conical radiation pattern and is fed by a hybrid coupler to obtain the dual-CP operation, which shows a stable performance with varisized metal reflectors. The measured results are consistent with the simulated ones in terms of good dual-CP conical patterns, which verified the effectiveness of the proposed design. All these features make the proposed antenna very suitable for vehicle-mounted satellite communication applications.
