Modern day communication devices house multiple communication, sensing and energy harvesting modules integrated into a single device. Therefore, it has become increasingly important to realize tunable radio frequency (RF) structures (e.g. antennas and filters) to reduce overall cost and size of the device by using a single RF structure for multiple modules. However, one of the key disadvantages of traditional RF structures is that they require complex electronics to tune their RF behavior. This work presents first-of-its-kind flexible broadband tunable origami-based RF structures such as frequency selective surfaces (FSS) and antennas using additive manufacturing techniques such as inkjet-printing and 3D-printing. The RF structures are designed using basic origami structures such as Miura-Ori and can be tuned on-demand by simply changing the shape of the structure. The Miura structure also allows realization of multilayer FSS structures without use of any complex mechanical fixtures or substrate between layers thereby considerably reducing the overall size, cost and complexity of the structure. The experimental results show that the origami-based FSS can significantly increase the angle of incidence rejection and bandwidth compared to traditional FSS. Moreover, the origami-based antennas demonstrate, for the first time, the possibility of integrating multiple antennas to the same origami structure thereby giving the user the flexibility and the freedom to choose a different type of antenna for a given application. These structures showcase for the first time the true potential of origami-based RF structures and their feasibility for future applications like Internet of Things (IoT) and Smart Skins (SS).
Abdullah Nauroze received his B.Sc. (honors) in computer engineering from University of Engineering and Technology, Taxila Pakistan in 2005 and M.Sc. in electrical engineering from Royal Institute of Technology (KTH), Stockholm, Sweden in 2008. During 2008-09 he worked at Microsystems Technology Laboratory (KTH), where he conducted research on on-chip millimeter-wave antennas for automotive radar and future wireless applications. He is currently pursuing his Ph.D. in electrical and computer engineering at Georgia Institute of Technology, Atlanta, USA where he is working as a Research Assistant at ATHENA lab. Mr. Nauroze has a teaching experience of seven (7) years. His research interests include application of additive manufacturing techniques like 3D printing and ink-jet printing for flexible and origami-based RF structures. He is also a recipient of prestigious Swedish Institute scholarship in 2006 and Fulbright Scholarship in 2014 for his masters and Ph. D. degrees respectively.
