摘要

这封信描述了一种双圆极化卫星导航微带天线的结构，该天线工作在北斗系统的B2b和L波段。机组采用双馈双层叠层结构，通过高介电常数和厚介电厚度实现小型化;通过在探头周围安装一圈金属孔，从而改善了端口之间的隔离;阻抗匹配是通过在顶部贴片中加载一个c形槽来实现的。仿真结果表明，端口间的隔离度分别为${S_{21}\，<\， - 26dB}$ (1.196~1.217GHz)和${S_{21}\，<\， - 20.2dB}$ (1.611~1.627GHz);在1.207和1.62GHz时，RHCP增益为5.12 dB, LHCP增益为5.92 dB。

A Miniaturized Dual-Band Stacked Structure Antenna Design

This letter describes the construction of a dual circularly polarized satellite navigation microstrip antenna that operates in the B2b and L bands of BDS. The unit is a double-fed double-layer laminated structure, with miniaturization achieved through high dielectric constant and thick dielectric thickness; the isolation between the ports is improved by fitting a ring of metal holes surrounding the probes leading to the top patch; impedance matching is accomplished through the inclusion of a C-shaped slot loaded in the top patch. The simulation results show the isolation between the ports is ${S_{21}\,<\, - 26dB}$ (1.196~1.217GHz) and ${S_{21}\,<\, - 20.2dB}$ (1.611~1.627GHz); At 1.207 and 1.62GHz, RHCP gain of 5.12 dB and LHCP gain of 5.92 dB are also observed.
