摘要：

A broadband high-efficiency reflectarray antenna using single-layer dipole element loaded with T-shaped stubs is proposed. The reflectarray unit cell is composed of a dipole element with two T-shaped stubs attached to each end of the dipole. A linear phase response with a coverage about 420 degrees is obtained by the proposed element. An offset-fed reflectarray antenna comprising 441 elements is designed, fabricated, and measured. The measured gain is 25.7 dBi at the design frequency of 10 GHz, corresponding to an aperture efficiency of 66.6%. In addition, a wide 1-dB gain bandwidth of 24% is achieved.
