ABSTRACT:
The invention combines a loop antenna and a dipole antenna in a conformal antenna on the rear window glass of an automotive vehicle above the defogging heater grid. The loop and dipole are adapted to receive Digital Audio Broadcasting (DAB) signals in both L band and Band-III frequency bands with maximum sensitivity to vertically polarized signals while requiring minimal space on the window glass. Inductive components separate portions of the antenna pattern for signals at predetermined frequencies in order to create the different effective antenna shapes at the different frequency bands.
