Abstract
An antenna () suitable for receiving circularly polarized RF signals from a satellite is integrated with a window () of a vehicle (), such as a roof window (). The antenna () includes a patch element () disposed adjacent to the window (). Radiating strips () forming at least one dipole pair are disposed below the patch element () and connectable to a transmission line. A coupling element () surrounds the radiating strips () and a dielectric layer () is sandwiched between the patch element () and the radiating strips (). A ground plane () is also disposed below the radiating strip (). A conductive casing () perpendicularly surrounds the antenna () elements while electrically connecting the ground plane () to the coupling element () such that the radiating strips () are generally disposed within a cavity ().
