Abstract

We demonstrate a metasurface-based flat reflectarray antenna with the capability of beam collimation and focusing. The reflectarray is designed to operate at 12GHz with a focal distance of 50cm in a center-fed configuration. It consist of 32 metallic patch resonators of variable sizes to cover a full 2π phase range. The reflectarray exhibits a measured gain enhancement of 28dBi at the central operating frequency of 11.8GHz and focuses at 50cm with a depth of focusing of 8cm and has a 3dB directionality ±1.6°. The demonstrated reflectarrays may enable low-cost, lightweight, and high-gain deployable transceivers for small-satellite platforms.
