Patent ID: 8564496

Claim:
A broadband antenna comprising: a substrate having a first surface, and a second surface opposite to said first surface; a first radiator arm disposed on said first surface; a second radiator arm disposed on said first surface, and connected to one end of said first radiator arm; a first grounding section disposed on said first surface; a first connecting conductor disposed on said first surface, said first connecting conductor having one end connected to a junction of said first radiator arm and said second radiator arm, and having another end connected to said first grounding section, said first connecting conductor having a feed-in point disposed thereon, said first connecting conductor including a first connecting section, a second connecting section and a third connecting section which are connected in sequence, said first and third connecting sections extending in one direction perpendicular to another direction in which said second connecting section extends; a second grounding section disposed on said second surface; a coupling conductor disposed on said second surface, at least a portion of said coupling conductor overlapping with a projection of said first and second radiator arms onto said second surface; and a second connecting conductor disposed on said second surface, having one end connected to said second grounding section, and having another end connected to said coupling conductor, at least a portion of said second connecting conductor overlapping with a projection of said first connecting conductor onto said second surface, said second connecting conductor including a first connecting segment, a second connecting segment, a third connecting segment, a fourth connecting segment and a fifth connecting segment which are connected in sequence, said second and fourth connecting segments extending in one direction perpendicular to another direction in which said first, third and fifth connecting segments extend; and wherein said substrate further includes a conductive via formed through said first surface and said second surface for connecting said coupling conductor to said first connecting conductor, said first radiator arm, and said second radiator arm at the junction of said first radiator arm and said second radiator arm.
