介绍了一种77GHz的具有一维波束重构能力的液晶微带反射阵。独立式反射器（无馈电）的特征在于其反射相位和幅度。虽然可以将反射相位调谐近300°，但相关的反射损耗仍然相当高。然而，当施加适当的DC控制电压时，反射阵列的图案测量显示出朝向不同角度的不同光束准直。（5页）
A 77 GHz liquid crystal microstrip reflectarray with beam reconfiguration capability in one dimension is presented. The free-standing reflector (without feed) has been characterized with respect to its reflection phase and magnitude. While it is possible to tune the reflection phase through almost 300°, the associated reflection losses are still quite high. Nevertheless the pattern measurements of the reflectarray showed distinct beam collimation towards different angles when appropriate DC control voltages are applied. (5 pages)
