摘要
提出了一种新型缝隙透镜天线结构。采用微带贴片加载透镜天线结构,即通过双H形槽耦合馈电实现圆极化激励,并在天线正前方加载合适介质透镜的天线结构,使天线的波束得到了适当压榨,且增益得到了提高,驻波比和轴比也均得到了改善。同时,该天线结构还具有结构紧凑、馈电简单、易于制造的优点。
This paper proposes a new slot lens antenna with a microstrip patch antenna loaded lens structure, that is, the double H-shaped slot coupled feed, to achieve circular polarization excitation. An appropriate dielectric lens antenna structure is adopted in front of the antenna to properly press the antenna beam and improve the gain, VSWR, and axial ratio. The antenna has the advantages of compact structure, Simple power supply, and easy manufacturing.
