ABSTRACT:
A radio antenna formed on a window pane includes parallel heating elements extending between busbars at opposite edges of the pane. Plural interconnecting elements extend across the heating elements. The length from the midpoint of a busbar to the point of connection of the interconnecting element, measured along the busbar and then along the heating element, is approximately λ/4+N(λ/2), where n is an integer greater than or equal to zero, and λ is a select wavelength from the band of signals to be received.
