提出了一种具有线性极化馈电的新型薄型宽带圆极化法布里-珀罗谐振器天线（CP-FPRA）。该天线的目标是在宽带宽中产生具有高增益水平的圆极化，同时保持薄型和简单的馈电配置。所提出的天线由一个沿 45° 线性极化排列的主辐射器、一个部分反射表面和一个充当反射接地平面的非标准人造磁导体组成。其轮廓可以减小到四分之一波长。此外，还提出并制造了一种使用 CP-FPRA 作为元件的 <inline-formula> <tex-math notation="LaTeX">$2\times 2$ </tex-math></inline-formula> 排列的阵列天线，具有紧凑的顺序旋转馈电方案，以增强增益并改善轴比（AR）带宽。该阵列经过优化，可以最大限度地减少光栅瓣并降低旁瓣电平，即使元件间距约为两个波长。观察到模拟结果和测量结果之间的合理一致性。测得 <inline-formula> <tex-math notation="LaTeX">$\vert \text{S}_{11}\vert \le -10$ </tex-math></inline-formula> dB、增益下降≤3 dB、AR ≤3 dB 的公共带宽约为 7.4%。
A novel low profile broadband circularly polarized Fabry-Perot resonator antenna (CP-FPRA) with a linearly polarized feed is proposed. The goal of this antenna is to generate circular polarization with high gain level in broad bandwidth, while maintaining low profile and simple feed configuration. The proposed antenna consists of a primary radiator aligned along 45° with linear polarization, a partially reflective surface, and a nonstandard artificial magnetic conductor acting as a reflective ground plane. Its profile can be reduced to a quarter of a wavelength. Furthermore, an array antenna of <inline-formula> <tex-math notation="LaTeX">$2\times 2$ </tex-math></inline-formula> arrangement using CP-FPRA as element with a compact sequential rotation feeding scheme is also proposed and fabricated to enhance the gain and to improve the axial ratio (AR) bandwidth. The array was optimized to minimize grating lobes and reduce the sidelobe level, even though the element spacing was about two wavelengths. Reasonable agreement between the simulated and measured results is observed. The measured common bandwidth of <inline-formula> <tex-math notation="LaTeX">$\vert \text{S}_{11}\vert \le -10$ </tex-math></inline-formula> dB, gain-drop ≤3 dB, and AR ≤3 dB is about 7.4%.
