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 pattern having a first plurality of arcuate break lines on one side of a dividing break line and a second plurality of arcuate break lines on the other side of the dividing break line. An elongated continuous blocking area is between adjacent break lines. The arcuate break lines of a group are nested within one another with the arcuate break line having the largest radius of curvature adjacent the dividing break line. The break lines each have alternating blocking and passing areas. In another embodiment, the enhanced frequency selective surface has 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.
