我们提出了适用于 G 频段（140GHz 至 220GHz）应用的 3D 微机械高架贴片天线。该天线由共面波导（CPW）馈线、馈电柱、空气桥、支撑柱和高架贴片组成。该天线拓扑结构有效地创建了低介电基板，并且可以消除不期望的基板效应，因为天线基板本质上是介电常数可能最低的空气。这将增加辐射效率、增益和辐射带宽。测量结果显示，带宽约为7GHz，从170GHz到177GHz，宽边辐射方向图几乎恒定。此外，这项工作还展示了在 MMIC 兼容工艺中制造高性能天线设计的能力。
We have proposed 3-D micromachined elevated patch antenna for G-band (140GHz to 220GHz) applications. The antenna is consisted of coplanar waveguide (CPW) feed line, a feeding post, air-bridge, supporting posts, and elevated patch. The antenna topology effectively creates a low dielectric substrate and undesired substrate effects can be eliminated, since the antenna substrate is essentially air which the lowest possible dielectric constant. This will increase the radiation efficiency, gain, and the radiation bandwidth. The measurement result shows the bandwidth is about 7GHz, from 170GHz to 177GHz with nearly constant broadside radiation pattern. Also, this work has demonstrated the capability of fabricating a high performance antenna design in a MMICs compatible process.
