A center-fed reflectarray antenna incorporating disk elements with attached phase-delay lines is proposed. Using this type of element, a single-layer reflectarray is fabricated and measured. In spite of utilizing a thin substrate, measurements show 3-dB gain bandwidth of 18%, centered at 11.7 GHz, demonstrating a wideband performance compared to the conventional designs.
