摘要

我们提出了一种60 GHz LTCC孔径耦合贴片天线，该天线具有集成Sievenpiper EBG结构，用于抑制TM模式表面波。这被认为是Sievenpiper EBG结构在毫米波LTCC天线内的首次演示。这种EBG结构的优点是在宽侧指向性方面可以提高6 dB。在没有EBG结构的情况下，表面波的边缘衍射使图案退化为两个主波束。新型LTCC材料系统(杜邦9K7 GreenTape™)与用于细线和细槽定义的激光烧蚀处理相结合，使EBG结构与孔径耦合贴片天线成功集成。

60 GHz patch antenna in LTCC with an integrated EBG structure for antenna pattern improvements

We present a 60 GHz LTCC aperture-coupled patch antenna with an integrated Sievenpiper EBG structure used for suppression of TM mode surface waves. This is believed to be the first demonstration of a Sievenpiper EBG structure used inside a millimeterwave LTCC antenna. The merit of this EBG structure is to yield a predicted 6 dB improvement in broadside directivity. Without the EBG structure, edge diffraction of surface waves degrades the pattern into two main beams. The combination of a new LTCC material system (DuPont 9K7 GreenTape™) along with laser ablation processing for fine line and fine slot definition allowed the integration of a successful EBG structure with an aperture coupled patch antenna.
