本文研究了一种共面波导馈电的矩形环缝隙天线，该天线具有内置调谐和直流返回功能。所提出的配置是可扩展的亚毫米波频率。为了设计和分析所提出的天线的阻抗特性，多层矩量法（MoM）求解器已开发的混合电位积分方程（MPIE）制定的基础上。利用几何光学和表面等效原理，得到了通过透镜的相应图案。三个模型已被模拟，其中一个已经建立和测试在65 GHz。该集成天线具有调谐能力、旋转对称方向图、高方向性、良好的高斯耦合效率和合理的带宽。此外，计算结果与测量结果吻合良好，并用于表征天线的输入阻抗和方向图行为。
A coplanar waveguide (CPW)-fed rectangular-loop slot antenna with built-in tuning and DC-return capabilities on extended hemispherical lenses is examined. The proposed configuration is scalable up to the submillimeter-wave frequencies. For designing and analyzing the impedance characteristics of the proposed antenna, a multilayer method of moments (MoM) solver has been developed based on the mixed potential integral equation (MPIE) formulation. The corresponding patterns through the lens are obtained using geometrical optics and the surface equivalence principle. Three models have been simulated and one of them has been built and tested at 65 GHz. The integrated antenna exhibits tuning capability, rotationally symmetric patterns, high directivity, good Gaussian coupling efficiency, and a reasonable bandwidth. In addition, computed results agree well with measurements and are used to characterize the input impedance and pattern behavior of the antenna.
