Patent ID: 7522118

Claim:
A wideband -shaped monopole dipole comprising a first dipole unit, a second dipole unit, a feed device, a parallel-wire and double-leads formed between cantilevers of said first and second dipole units, said parallel-wire connecting said first dipole unit with said second dipole unit in a parallel connection, said feed device comprising a feed pad and a coaxial cable, wherein said double-leads between said cantilevers of said first and second dipole units extend to form parallel plates acting as a first balancer and a second balancer to balance impedance components of said first and second dipole units, said feed device is disposed on a center portion of the parallel-wire, the feed pad is arranged on one line of the parallel-wire, and outer and inner conductors of said coaxial cable connect with said feed pad and the other line of said parallel-wire, respectively.
