Spoiler antenna

A band-pass filter comprising:

• a parasitic element extending a first distance;
• and
• a first electrical conductor comprising:
• a first branch extending a second distance, the second distance at least partially overlapping and extending parallel to the parasitic element;
• and
• a second branch extending a third distance, the third distance at least partially overlapping and extending parallel to the parasitic element,
• wherein the first branch overlaps the parasitic element along a first length, the first branch and the parasitic element being electromagnetically coupled along the first length,
• wherein the second branch overlaps the parasitic element along a second length, the second branch and the parasitic element being electromagnetically coupled along the second length,
• wherein the first length corresponds to a first frequency, and
• wherein the second length corresponds to a second frequency.

A spoiler antenna assembly for an automobile, the assembly comprising:

• a spoiler mounted to the automobile, the spoiler comprising a spoiler substrate;
• and
• a spoiler antenna disposed on the spoiler substrate, the spoiler antenna comprising:
• a first electrical conductor extending a first distance;
• a second electrical conductor extending from the first electrical conductor, the second electrical conductor extending a second distance, a portion of which is parallel to the first distance;
• and
• a third electrical conductor extending a third distance parallel to and between the first electrical conductor and the second electrical conductor,
• wherein the first electrical conductor and the third electrical conductor at least partially overlap along a first length, the first electrical conductor and the third electrical conductor being electromagnetically coupled at least along the first length,
• wherein the second electrical conductor and the third electrical conductor at least partially overlap along a second length, the second electrical conductor and the third electrical conductor being electromagnetically coupled at least along the second length,
• wherein the first length corresponds to a first frequency, and
• wherein the second length corresponds to a second frequency.
