Abstract: A device attachable to a substrate for improving penetration of wireless communication signals is provided. The device is a bendable resin configured to enhance penetration of an incidental radio wave from a first region through the substrate to a second region by forming one or more communication signal beams in the second region. The bendable resin includes a base layer of a first material, and one or more patterned elements each formed by providing a meta-pattern of a second material on the base layer. The first and second materials are different and selected from the group consisting of a dielectric material and a metallic material. Each individual patterned element is configured to tilt the incidental radio wave to form the one or more communication signal beams, wherein each individual communication signal beam is beam-focused at a predetermined focal point or a predetermined focal area in the second region.
