Abstract: 
We present a novel broadband circularly polarized (CP) antenna with filtering effect for X- and Ku-band satellite wireless communication. The structure comprises a driven layer (also a filtering layer) and a stacked layer (also a CP layer). The bandpass filtering response consists of two radiation nulls, which is the combined effect of a substrate integrated waveguide (SIW) cavity-backed aperture and embedded driven patch. The chamfered patch is introduced as the stacked component with the ability to achieve CP and widen the operating bandwidth. A prototype with a compact layout of 0.8λ0×0.71λ0×0.16λ0 is fabricated using a multilayer printed circuit board (PCB) process for demonstration. Experimental results are in good agreement with the simulation results, and show that the measured -10-dB impedance bandwidth and 3-dB axial ratio (AR) bandwidth are 10.83% and 15.54%, respectively. In addition, a peak gain of 8.9 dBic for left-hand circular polarization (LHCP), an average in-band gainLHCP > 7 dBic, and good frequency selectivity are obtained.

摘要:文章提出一种应用于 X 频段和 Ku 频段卫星无线通信的带有滤波效应的新型宽带圆极化天线。该结构包含一个驱动层(同时也是滤波层)以及一个堆叠层(同时也是圆极化层)。带通滤波响应中的两个辐射零点,是衬底集成波导(SIW)腔体支持的开口与嵌入式驱动贴片的综合效果。引入倒角贴片作为堆叠元件,具有同时实现圆极化和拓宽工作带宽的能力。使用多层印制电路板(PCB)工艺制作了一个尺寸为 0.8λ0×0.71λ0×0.16λ0 的紧凑原型进行演示。实验结果与仿真结果吻合良好,测量的 −10-dB 阻抗带宽和 3-dB 轴比带宽分别为10.83% 和 15.54%。此外,还获得了 8.9 dBic 的左旋圆极化峰值增益,大于 7 dBic 的带内平均左旋圆极化增益,以及良好的频率选择性。
