摘要
卫星通信(SatCom)需要一种具有双正交旋转的双波段圆极化(CP)天线。这封信提出了一种新的频率选择性反射面,可在 C 波段和 X 波段的四个离散频率上将线性极化(LP)波转换为 CP 波。在每对频率上反射信号的双 CP 旋转可用作 C 波段和 X 波段卫星通信的上行链路/下行链路。四个 LP-CP 转换频率分别为 C 波段的 6.8 和 7.44 千兆赫,X 波段的 9.92 和 11.12 千兆赫。四波段极化转换器的原型已经制作完成,测量响应与模拟结果非常吻合。
Quad-Band Linear-to-Circular Polarization Reflecting Surface With Dual Orthogonal Rotation for C/X-Band Uplink/Downlink SatCom Applications
Satellite communication (SatCom) demands a dual-band circularly polarized (CP) antenna with dual-orthogonal rotation. This letter proposes a new frequency selective reflecting surface that transforms a linearly polarized (LP) wave to a CP wave at four discrete frequencies in the C- and X-bands. The dual-CP rotation of the reflected signal at each pair of frequencies can be utilized as uplink/downlink for C- and X-bands SatCom. Four LP-to-CP conversion frequencies are 6.8 and 7.44 GHz in the C-band and 9.92 and 11.12 GHz in the X-band. A prototype of the quad-band polarization converter was fabricated, with measured responses closely matching simulated results.
