Patent ID: 7800550

Claim:
A dipole antenna array, comprising: a dielectric substrate, having a first surface and a second surface opposite to the first surface; a plurality of first electric tuning elements, mounted on the first surface and the second surface of the dielectric substrate; a plurality of resonance elements, mounted on the first surface of the dielectric substrate, each resonance element including a first resonance part, a second resonance part and a third resonance part, the second resonance part connecting the first resonance part to the third resonance part, a first slot being formed on each of opposite sides of the second resonance part, a second slot being formed between one end of the third resonance part away from the second resonance part and one end of the electric tuning element close to the third resonance part, a third slot being formed on the end of the third resonance part away from the second resonance part; a plurality of ground elements, mounted on the second surface of the dielectric substrate, each ground element including a first ground part, a second ground part and a third ground part, the second ground part connecting the first ground part to the third ground part, another first slot being formed at each of the opposite sides of the second ground part, another second slot being formed between one end of the third ground part away from the second ground part and one end of one electric tuning element close to the third ground part, a third slot further being formed on the end of the third ground part away from the second ground part; and a feed line, electrically connecting to at least one resonance element and at least ground resonance elements.
