Patent ID: 7636069

Claim:
A broadband dipole antenna comprising: a dielectric substrate; a metal layer, formed on the dielectric substrate; a feed gap, which is substantially a V shape or U shape, formed on the dielectric substrate by etching the metal layer; a first radiating portion, formed from the etched metal layer and located on the dielectric substrate, the first radiating portion comprising: a first radiating part; a second radiating part connected to the first radiating part; and a third radiating part connected to the first radiating part; wherein the feed gap is surrounded by the first radiating part, the second radiating part and the third radiating part; a second radiating portion, formed from the etched metal layer and located on the dielectric substrate, forming a substantial V shape with the first radiating portion, the V shape having a flare angle between 30 and 180 degrees, the second radiating portion comprising: a fourth radiating part; and a fifth radiating part, connected to the fourth radiating part and surrounded by the feed gap; a first feed point, located at a first terminal of the second radiating part of the first radiating portion; wherein the first terminal of the second radiating part of the first radiating portion is adjacent to the feed gap; and a second feed point, located at a second terminal of the fourth radiating part of the second radiating portion; wherein the second terminal of the fourth radiating part of the second radiating portion is adjacent to the feed gap; wherein the first and the second feed points are separated by the feed gap.
