Abstract:
1. A broadband antenna apparatus comprising: a substrate having a conducting ground plate; a three-dimensional rectangular parallelepiped member disposed on the substrate; a radiating conductor disposed on at least three adjacent sides of the three-dimensional rectangular parallelepiped member and having a feedpoint positioned adjacent to, but electrically insulated from, the conducting ground plate, and said feedpoint configured to have electrical power transmitted thereto by a feed mechanism, the radiating conductor including a first quarter-circular pattern formed on a first side of the rectangular parallelepiped member parallel to the ground plate, a second quarter-circular pattern formed on a second side of the rectangular parallelepiped member perpendicular to the ground plate, and a third quarter-circular pattern formed on a third side of the rectangular parallelepiped member perpendicular to the ground plate; and a first resistance material extending across the second and third quarter-circular patterns.
