Reflection array antenna based on orthogonal direction phase independent control reflection unit

The invention belongs to the technical field of antennas, and particularly relates to a reflective array antenna based on orthogonal direction phase independent control reflection units. According to the structure, units capable of independently controlling phases in the orthogonal direction are mainly provided, reflection phases in two directions are controlled through two diodes in each unit, the phase difference of the x axis and the y axis of the unit structure is +/-90 degrees, only linear polarization feed is needed for achieving circular polarization, different structures are used, and therefore the x, y and y axes of the unit structure are different, and the phase difference between the x axis and the y axis of the unit structure is +/-90 degrees. The phase difference of the y axis has a larger degree of freedom in design. 本发明属于天线技术领域，具体的说是涉及一种基于正交方向相位独立控制反射单元的反射阵天线。本发明的结构主要提出可以在正交方向上独立控制相位的单元，每个单元中通过两个二极管分别控制两个方向的反射相位，本发明的单元结构x,y轴的相位差为±90°，实现圆极化仅需线极化的馈电，使用了相异的结构，使得x,y轴的相位差在设计上具有更大的自由度。
