Penggunaan Dual-Layer Substrate untuk Meningkatkan Bandwidth Antena Mikrostrip pada Frekuensi LTE

open access: yesJurnal Nasional Teknik Elektro, 2018
Narrow bandwidth is one of the problems in a microstrip antenna. Bandwidth enhancement is proposed by applying dual-layer in the substrate. The bottom layer is made from a single-layer circular microstrip antenna design by applying the formula to get an ...

Adaptable Tile‐Based Pneumatic Origami through Structurally Coupled Localized Actuation

open access: yesAdvanced Engineering Materials, EarlyView.
This article presents tile‐based pneumatic origami structures with rigid tiles and flexible fabric creases, achieving adaptable properties including morphing shape, selective multistability, and tunable stiffness. Independently pressurized folding bladders at each crease enable structurally coupled localized actuation of origami structures.
