Abstract:
1. An antenna apparatus comprising: a circuit board comprising a plurality of dipole antenna elements including inductive and capacitive elements, and a quarter-wave sleeved balun and coaxial cable feed assembly connected to said circuit board, and wherein said plurality of dipole elements comprise a first section and a second section, said first section is located on the bottom side of said circuit board, and said second section is located on the top side of said circuit board and is substantially perpendicular and capacitively coupled to said first sections, and said plurality of dipole elements are laterally offset from each other to create an overlapping of the capacitively coupled elements, and wherein said inductive and capacitive elements are in series with a pair of J shaped elements, and said pair of J shaped elements are patterned onto the circuit board in a clockwise direction, wherein, a first J shaped element is starting to the left and a second J shaped element is starting to the right of said quarter-wave sleeved balun and coaxial cable feed assembly.
