1. A window assembly comprising:
- a transparent panel; and
a conductive heater grid formed integrally with the transparent panel, the heater grid having a first group of grid lines and a second group of grid lines with opposing ends of the first group of grid lines and the second group of grid lines being connected to first and second busbars;
at least one grid line of the second group is located between adjacent grid lines of the first group; and
wherein the height of the grid lines in the second group is less than the the height of the grid lines in the first group.

Abstract
The present invention provides a window assembly having a transparent panel and a conductive heater grid formed integrally with the transparent panel. The conductive heater grid has a first group of grid lines and a second group of grid lines, with opposing ends of each group being connected to first and second busbars. Grid lines of the second group are spaced between adjacent grid lines of the first group, with the height of the grid lines themselves in the second group being less than the height of the grid lines in the first group.
