Orthoplanar springs are single-component compliant mechanisms that can be fabricated from sheet material and undergo deflection orthogonal to the plane of the mechanism. They are useful in applications where spatial constraints are significant. An Eu

Abstract Microwave absorbers have been used to mitigate signal interference, and to shield electromagnetic systems. Two different types of absorbers have been presented: (a) low-cost narrowband absorbers that are simple to manufacture, and (b) expens

In this paper, a novel deployable flat panel reflectarray antenna (RA) is designed on an origami folding pattern for Small Satellite applications. The RA aperture deploys into a hexagonal geometry that achieves an aperture efficiency of a least 60%,

An origami-based foldable and reconfigurable Reflectarray Antenna (RA) with multiple apertures is proposed for CubeSat applications. The proposed configuration consists of a central RA embedded in folding panels using Lamina Emergent Torsional (LET)

Deployable origami arrays have been used to increase the aperture areas of spacecraft instruments. Folds within these patterns allow the arrays to fold compactly, but can also cause un-desired folding when in the deployed state. In addition, there is

This paper presents a systematic approach for selecting an origami source pattern for deployable space array applications, followed by two case studies used to demonstrate the selection process. Applying origami principles to form engineering solutio

Origami patterns have been used in the design of deployable arrays. In engineering applications, paper creases are often replaced with surrogate folds by providing a hinge-like function to enable motion. Overconstraint observed in multivertex origami
