The antenna slot may be fed directly by a voltage probe or a coupled coplanar line re) at a position to excite both fundamental and higher order modes for multiband antenna applications. A portion of the 1R reflective h coating may overlay the window frame at null positions of first higher order mode to tune the slot antenna to higher frequencies. Slot --..., antenna resonant frequency may also be moved higher by separating the 1R reflective coating into two coating panel with the lower coating panel connected to electrical ground by capacitive coupling. Multiple antennas can be fed at different locations for multiband applications and diversity antenna systems. C.)
