Abstract
Techniques are provided for fabricating a low profile antenna that operates with increased efficiency. An antenna implementing the techniques according to an embodiment includes a first arm comprising a first spiral portion and a first rectilinear portion, and a second arm comprising a second spiral portion and a second rectilinear portion. The second spiral portion is concentric with the first spiral portion. The antenna further includes an insulator to separate the arms. The insulator and the arms are planar surfaces disposed within a rectangular region. The first rectilinear portion is adjacent to a first and second side of the perimeter of the rectangular region, and the second rectilinear portion is adjacent to a third and fourth side of the perimeter of the region. The antenna is fabricated as a printed circuit board which is mounted on the fuselage of an aircraft, which serves as a ground plane for the antenna.
