Traditionally, antennas have been thought of as solid, rigid-bodied objects. The properties of these antennas have been studied extensively. Recently, origami antennas have attracted attention due to their unique advantages. Specifically, origami antennas are reconfigurable, efficiently packable and effortlessly deployable. Moreover, such antennas can tune their performance in terms of operating resonant frequency , polarization , and radiation pattern . This work focuses on the analysis and modeling of a helical Kresling origami antenna. First, nested and inter-dependent variables and functions are developed to define the geometry of this antenna. Then, MATLAB code is developed to create the antenna model in ANSYS HFSS via visual basic scripts, so that the structure is generated efficiently by defining its fundamental parameters. In fact, our code could be customized for any 3D electromagnetic (EM) software that supports scripting interfaces. In addition, our code enables the quick generation of helical Kresling origami antennas, i.e., geometries can be created in minutes compared to manual drawing that could take days. Furthermore, each layer of these antennas is defined independently, so that each can be uniquely folded to a different degree, thereby improving their reconfigurability. Finally, our is used to analyze the performance of such antennas in terms of frequency of operation, polarization and radiation pattern. References:  X. Liu, S. Yao and S. V.
