Abstract
Reconfigurable antennas are an emerging class of antennas that have a wide range of applications in the areas of wearable electronics and wireless communications. Previous research efforts have been focused on reconfiguration of antennas to enable changes in antenna electromagnetic (EM) wave properties such as radiation characteristics, resonant frequency and direction of propagation. Through reconfiguration of the antenna such as folding, or deformation, resonant frequency, gain, and direction of radiation can be fined tuned. To examine a new approach to concepts of the previous works, this research devises methods to yield reconfigurable antenna that deliver EM properties that are independent of configuration. Such as consistent resonant frequency, gain, and radiation despite folding and deformation. To study significant reconfiguration potential, this research explores the use of the miura-ori origami inspired tessellation array as basis for reconfigurable antennas. To overcome the technical challenges of reconfigurable antennas, this research implements design methods that allow for antennas to be deformed by utilizing flexible substrates and thin copper laminates. The reconfigurable antennas are assessed through a finite element modeling software and followed by experimental fabrication and testing. Tessellation based antennas allow for a large shape change resulting in the ability to analyze and understand how deformation effects the behavior of the antenna. The results of this research demonstrate that the tessellation-based patch antenna which provides folding capabilities and large deformation enables for electromagnetic wave characteristics that are independent of configuration.
