We demonstrate experimentally that a block of extremely anisotropic metamaterial formed by an array of metallic wires embedded into a dielectric material is a near-field radome. The radome is intrinsically multiband and can operate, for instance, in both GSM frequency bands. The structure both hides an antenna from external mechanical and environmental influence and transmits its near-field onto an outer interface in contrast to conventional radomes that alter antenna characteristics and have to be taken into account during design process.
