Abstract
An antenna includes a support and an electroconductive first antenna element, e.g., an electroconductive coating, located on the support and spaced from at least one electroconductive second antenna element. The first antenna element is connected to a ground through an electronic filter device, such as an inductor, configured to pass selected frequencies, e.g., AM frequencies, to the ground to eliminate the selected frequencies from the signal provided by the first antenna element. The first antenna element is preferably located between the second antenna element and a source of electronic noise to shield the second antenna element from at least a portion of the electronic noise. The second antenna element receives and provides at least one of the selected frequencies passed to the ground from the first antenna element.
