摘要翻译：
提出了一种新型的微波区矢量涡束发射装置的设计方案。该光束是通过将金属圆波导的单导横向电(TE)模发射到自由空间而形成的。激励是通过插入的同轴环形天线实现的。计算了模态展开系数，并确定了所产生的电场和磁场。利用传输线关系，模拟了天线在波导中的位置对其有效输入阻抗的影响，并建立了最佳匹配位置。用多级快速多极子法全波模拟验证了分析结果。

英文摘要：
  A novel design for a vectorial vortex beam launcher in the microwave regime is devised. The beam is formed by launching a single guided transverse electric (TE) mode of a metallic circular waveguide into free-space. Excitation is achieved by the mean of an inserted coaxial loop antenna. Modal expansion coefficients are computed, and the resulting electric and magnetic fields are determined. The effect of the antenna location inside the waveguide on its effective input impedance is modelled using transmission-line relations and location for optimal matching is established. The analytical results are confirmed using multi-level fast multipole method full-wave simulations.
