More specifically, we consider the challenging case of a half-wavelength dipole working in close electrical proximity to an Archimedean spiral slot antenna. We show that by covering the dipole with a suitable cloaking metasurface, it is possible to significantly reduce its blockage on the Archimedean antenna and make it work as if it were isolated. We also show that the same system can be engineered to exploit the aperture antenna as a reflector for the dipole that, thus, can operate as a standard sector antenna. This cloaking application is confirmed by realistic full-wave numerical simulations.
