• Broadband reflectarray
• high gain antenna
• multidipole element

A broadband microstrip reflectarray with five parallel dipole elements is proposed. Based on the operating mechanisms and the reflection phase characteristics of the five-dipole elements, the elements for the broadband reflectarray are designed. The radiation patterns of the five-dipole element reflectarray with the design frequency of f(0) = GHz are measured, and 1-dB gain bandwidth of 33.52% is achieved. The measured peak gain at f(0) = 15 GHz is 31.4 dBi, which corresponds to the high aperture efficiency of 64.1%.
