摘要

这封信提出了一个双频和圆极化微带天线，具有双帧贴片和插槽加载在其外侧。基于多模谐振理论，通过四臂导电电桥实现内外框架间的容量耦合，实现了CNSS在1.616 GHz和2.492 GHz的双频工作。在所提出的双框架结构的不同方向上引入微扰，以实现双手圆偏振。此外，由于负载在地平面的EBG缺陷抑制了高次谐波，使得天线的辐射效率和增益得到了提高和平衡。双帧微带天线的仿真与实测结果吻合良好，具有良好的性能。

A Dual-frame microstrip antenna with four-bridge feeding control for CNSS applications

This letter presents a dual-band and circular polarization microstrip antenna, with a dual-frame patch and slots loaded on its external sides. Based on the multimode resonant theory, a dual-band operation at 1.616 GHz and 2.492 GHz for CNSS applications is realized by the capacity coupling between the frames inside and outside through four-arm conductive bridges. The perturbation is introduced in different directions of the proposed dual-frame structure to achieve dual-hand circular polarization. In addition, the radiation efficiency and gain of the designed antenna are improved and balanced by the suppression of high-order harmonics, due to an EBG defect loaded in the ground plane. The simulation and measurement of the dual-frame microstrip antenna agree well, and the results show good performances.
