1. A circular antenna array for vehicular direction finding applications, comprising:

  • a circular disc constructed from dielectric material, the disc having a concentric hole of a given diameter, and top and bottom sides;

    a concentric, circular ground plane formed on the bottom side of said circular disc; and

    a plurality of directional microstrip antennas radially spaced at equal angles around the hole, the plurality of antennas having elements disposed on the top and bottom sides of the disc, the plurality of antenna elements being microstrip elements of conductive material, wherein each said directional microstrip antenna comprises;

    a top leg extending radially from the concentric hole formed through the circular disc and being mounted on the top side thereof;

    a top arm extending from a distal end of the top leg;

    a bottom neck extending radially from the concentric, circular ground plane and being mounted on the bottom side of the circular disc; and

    a bottom arm extending from a distal end of the bottom neck.
