论文名称为“An S- and V-band dual-polarized antenna based on dual-degenerate-mode feeder for large frequency ratio shared-aperture wireless applications”。该文提出了一种共孔径S / V波段双极化天线，该天线包括一个2.4 GHz贴片和一个60 GHz SIW平行板正交长槽阵列，并设计了一种由圆波导和同轴腔组成的双简并模馈线，用于激励双频双极化天线。利用圆波导的两个简并主模和一个180◦五端口魔T实现V波段双极化差分馈电，采用这种差分馈电方法，v波段长缝隙阵列天线的波束方向在带内具备定向性。利用同轴腔的两个简并高阶模TE1 1,1,0.5和TE2 1,1,0.5实现s波段双极化馈电。用于两个正交极化馈电的两个SMA连接器被放置在各自的电场零点上，以增加输入端口之间的隔离。工作主要完成人张锦帆、程钰间、丁嫣然。

Abstract— An S-/V-band dual-polarized antenna is proposed for large frequency ratio shared-aperture wireless applications, which includes a 2.4 GHz patch and a structural-reused 60 GHz substrate integrated waveguide (SIW) parallel-plate orthogonal long-slot array. A dual degenerate-mode feeder including a circular waveguide and a coaxial cavity is designed to excite the developed S-/V-band shared-aperture dual-polarized antenna. Two degenerate dominant modes of the circular waveguide and a 180◦ hybrid junction with five ports are used to realize the dual-polarized differential feeding at V-band. By the use of this differential feeding method, the beam direction of the V-band long-slot array antenna is unchanged with the frequency. Two degenerate highorder modes TE1 1,1,0.5 and TE2 1,1,0.5 of the coaxial cavity are used to realize the dual-polarized feeding at S-band. Two SMA connectors for two orthogonal-polarized feeding are placed at their respective electric field minimum points to increase the isolation between input ports. Finally, the dual-band dual-polarized antenna is fabricated and measured.
