Abstract
This thesis describes a novel design of a reconfigurable modulated metasurface(MTS) antenna. Currently, antennas are designed and created with exact parameters to meet specific demands. In the ever-changing world of space communication or the Internet of Things, the demands can change in an instant. The proposed antenna is composed of a modulated metasurface, and a ground plane connected with two Piezoelectric actuators. The actuators provide the means for changing the distance between the metasurface and the ground plane to adjust the direction in which the antenna is radiating. A single unit cell is studied and used to configure the modulation in the metasurface. This paper also discusses the preliminary design considerations for the ability of the antenna to beam steer as well as techniques for optimization. The performance of the antenna has been verified by full-wave simulations in hopes of fabrication and testing in the future for further verification. This thesis also discusses the laws and properties that define the behavior of electromagnetic waves as well as the mediums they travel through. The history of metamaterials is covered as well as the research for metasurfaces that is currently in use. Metasurfaces offer advantages in terms of size, weight, cost, and scalability compared to traditional optical systems for the same functionality in various fields of technology
