基于准共形坐标变换，给出了共形阵列天线的透镜设计。潜在地在用于二维TE偏振的宽带宽上，使用仅具有非磁性介质参数的透镜可以将物理线性阵列变换为虚拟曲线阵列，反之亦然。给出了共形导电接地板中线列阵和柱面阵之间变换的透镜设计及其预测的扫描性能。这种透镜可以设计并应用于现有的阵列天线，以实现新的扫描能力。
Based on quasi-conformal coordinate transformation, lens designs for conformal array antenna applications are presented. Potentially over a broad bandwidth for the two-dimensional TE polarization, a physically linear array can be transformed into a virtual curved array, or vice versa, using a lens having only nonmagnetic medium parameters. Lens designs for transforming between linear and cylindrical arrays in conformal conducting ground planes as well as their predicted scanning performances are shown. Such lenses can be designed and applied to existing array antennas to enable new scanning capabilities.
