Patent ID: 7042415

Claim:
A dual band and broadband flat dipole antenna, comprising: a first radiating body, which has at least two first frequency-radiating parts, at least two second frequency-radiating parts, and a first electrically connecting part, wherein the first frequency-radiating parts of the first radiating body and the second frequency-radiating parts of the first radiating body are extended from a side of the first electrically connecting part, and the second frequency-radiating parts of the first radiating body are disposed between the first frequency-radiating parts of the first radiating body; a second radiating body, which has at least two first frequency-radiating parts, at least two second frequency-radiating parts, and a second electrically connecting part, wherein each of the first frequency-radiating parts of the first radiating body and the second radiating body has a first length and a first width, each of the second frequency-radiating parts of the first radiating body and the second radiating body has a second length and a second width, the first frequency-radiating parts of the second radiating body and the second frequency-radiating parts of the second radiating body are extended from a side of the second electrically connecting part with a direction reversing to an extending direction of the first radiating body, and the second frequency-radiating parts of the second radiating body are disposed between the first frequency-radiating parts of the second radiating body; and a conductivity element, which has a conductivity body and a ground conductor, wherein the conductivity body and the ground conductor are electrically connected with the first electrically connecting part and the second electrically connecting part, respectively.
