摘要: 为了降低天线对载体气动力学的破坏，提高天线在复杂电磁环境中的性能，该文设计了一款圆极化方式可重构的端射天线。该天线以基片集成波导(SIW)喇叭天线为原型，在喇叭前端加载移相器和蝶形振子，上下蝶形振子之间加载了4个MEMS开关，开关的导通与断开，可以控制电流的流动路径，从而使天线分别辐射两种圆极化波。实测结果表明，通过控制开关的通断组合，设计的天线可以在11.24～11.83 GHz频段内沿端射方向辐射左旋圆极化(LHCP)或右旋圆极化(RHCP)电磁波。测量结果和仿真结果基本吻合，验证了设计的有效性。Abstract: In order to reduce the damage to carrier aerodynamics by the antenna and improve the performance of the antenna in a complex electromagnetic environment, this paper designs a circularly polarized reconfigurable end-fire antenna. The antenna is based on the Substrate Integrated Waveguide (SIW) horn antenna. The front end of the horn is loaded with a phase shifter and butterfly dipoles, and four MEMS switches are loaded between the upper and lower butterfly dipoles. The current flow path can be controlled by the on and off of the switch, so that the antenna radiates two circularly polarized waves respectively. The measured results show that by controlling the on-off combination of the switch, the designed antenna can radiate Left-Hand Circular Polarization (LHCP) or Right-Hand Circular Polarization (RHCP) electromagnetic waves in the 11.24～11.83 GHz frequency band along the end-fire direction. The measurement results are basically consistent with the simulation results, verifying the effectiveness of the design.
