中文摘要：

利用低温共烧陶瓷（LTCC）工艺制作以陶瓷作为基板的双层圆极化微带阵列天线。传统设计中,使用柔性基板制作多层寄生微带阵列天线,由于加工精度及基板之间空气层的原因,阵列天线的圆极化特性以及阻抗匹配与仿真结果相差较大。该文采用低损耗高频陶瓷材料设计了应用于X波段的16单元双层圆极化微带阵列天线。通过实际测试,16单元阵列天线具有较好的带宽和圆极化特性,从而验证了LTCC技术可以很好地应用于微带阵列天线的研制。

英文摘要：

Low temperature Co-fired ceramic （LTCC） technology is used in the fabrication of circularly polarized two-layer micro-strip array antenna taking ceramic as the substrate. In conventional design, multi-layer parasitic micro-strip array antenna is fabricated with flexible substrate material. However, due to the machining accuracy and air layer between substrates, the circular polarization characteristics and impedance match of the antenna array is greatly different from the simulation results. In this article, 16 elements two-layer micro-strip array antenna was designed with low-loss high-frequency ceramic material at X-band. In practice testing, the 16 elements array antenna had good bandwidth and circular polarization characteristics, proving that LTCC technology could be well applied to the fabrication of micro-strip antenna array.
