摘要
A novel approach is proposed to suppress the frequency-dependent beam squint of offset-fed reflectarray patterns. The design comprises two offset feeds located at opposite ends of the reflectarray, in the plane of offset, simultaneously illuminating the reflectarray. This generates a single beam that does not squint from the desired design direction at off-center frequencies. The concept is validated by comparing the full-wave simulated patterns to measured counterparts.
