   Sammanfattning : With the advent of the 5G technology standard for communication, it is esti-mated that around 50 billion devices around the world will be interconnectedunder this standard [1]. This has prompted the need to investigate new ma-terials, technologies and methods to conceal antennas for preserving the aes-thetic value of urban centers, and preventing these antenna systems from beingidentified or damaged.
