The invention discloses an electronic control beam scanning reflection array antenna and a beam scanning method thereof. The antenna is low in cost and loss and simple in structure. The antenna is characterized in that two initial feed sources are adopted in the antenna to perform irradiation excitation on a reflective array plane, and the excitation amplitude ratio of the feed source 1 to the feed source 2 is changed to change the phase value distribution of a total incident field in the array plane so that electronic control beam scanning can be achieved. The antenna is simple in structure and does not need extra biasing circuits, so that machining is convenient, and stability is high. High-gain beam scanning can be achieved just through the two initial feed sources without extra T/R modules, so that the manufacturing cost is effectively lowered. The antenna is suitable for microwave or millimeter wave or terahertz frequency bands and can be used in wireless communication and radar systems.

The present invention discloses a reflect array antenna with a controllable side-lobe level and a method for the same, and belongs to the fields of a wireless communication technology, a radar technology and an imaging technology. By introducing a structure variable capable of controlling insertion loss into a basic periodic unit of the reflect array antenna and enlarging an insertion loss amplitude variation range, a phase error of introduction is simultaneously guaranteed to be kept smaller than a fixed value in the integral variable changing range.
