Origami Antennas For Novel Reconfigurable Communication Systems, Xueli Liu
Origami Antennas For Novel Reconfigurable Communication Systems, Xueli Liu
FIU Electronic Theses and Dissertations
Antennas play a crucial role in communication systems since they are the transmitting/receiving elements that transition information from guided transmission to open-space propagation. Antennas are used in many different applications such as aerospace communications, mobile phones, TVs and radios. Since the dimensions of antennas are usually physically proportional to the wavelength at their operating frequencies, it is important to develop large antennas and arrays that can be stowed compactly and easily deployed. Also, it is important to minimize the number of antennas on a platform by developing multifunctional antennas.
The first aim of this research is to develop new deployable, …

Origami Reconfigurable Electromagnetic Systems, Shun Yao
FIU Electronic Theses and Dissertations
With the ever-increasing demand for wireless communications, there is a great need for efficient designs of electromagnetic systems. Reconfigurable electromagnetic systems are very useful because such designs can provide multi-functionality and support different services. The geometrical topology of an electromagnetic element is very important as it determines the element’s RF performance characteristics. Origami geometries have significant advantages for launch-and-carry electromagnetic devices where devices need to fold in order to miniaturize their size during launch and unfold in order to operate after the platform has reached orbit.
This dissertation demonstrates a practical process for designing reconfigurable electromagnetic devices using origami structures. …
