1. A printed circuit board (PCB) comprising: an array of transmission lines having at least one row of multiple columns, each transmission line configured to transmit or receive electromagnetic energy; and a metal layer comprising: waveguide interface openings for surrounding each transmission line in the array of transmission lines, each waveguide interface opening being a portion of the metal layer where the metal has been removed; and multiple isolation slots configured to form a stop band for a frequency band of the electromagnetic energy, an isolation slot being disposed on each side of each column in the array of transmission lines such that an isolation slot is aligned in the at least one row on each side of each waveguide interface opening, each isolation slot being a portion of the metal layer where the metal has been removed.
