An electrically conductive coating of an automotive heatable windshield has a communication window having an enhanced frequency selective surface having arranged passing areas (uncoated areas) and blocking areas (coated areas) to pass and block, respectively, predetermined wavelengths of the electromagnetic spectrum. In one nonlimiting embodiment, the frequency selective surface includes a plurality columns spaced from one another by a continuous elongated blocking area. Each of the columns includes passing areas with each of the passing areas have a perimeter with a blocking area in the perimeter spaced from the perimeter. The perimeters of the passing areas contact one another with the blocking area of adjacent passing areas spaced from one another. The elongated blocking area between the break lines and columns extend to the perimeter of the communication window. In this manner current passing through the coating, passes through the communication window to eliminate hot and cold spots around and within the perimeter of the communication window.
