Patent ID: 8184063

Claim:
A balanced dipole antenna, comprising: a left dipole arm having a center end, a right dipole arm having a center end, a coaxial cable having an outer conductor and a single inner conductor and a top end electrically located between the center ends of the left and right dipole arms, a left stub coupling the left dipole arm and the coaxial cable, and a right stub, symmetric to the left stub in all dimensions with respect to a longitudinal axis of the coaxial cable, coupling the right dipole arm and the coaxial cable, wherein the inner conductor of the coaxial cable is connected to one of the left and right dipole arms, and the outer conductor of the coaxial cable is connected to the other of the left and right dipole arms; and wherein the left and right stubs substantially eliminate radiative coupling between the coaxial cable and the left and right dipole arms.
